Introduction

Yes this is a security course, and yes security concepts are an important part of any security course, however, ethics is just as important. Within the cybersecurity field we are often given access to much of the organizational assets in order to do our job. Along with this access comes great responsibility to guard these assets and keep them safe, including from ourselves. This is where the ethics part of the cybersecurity equation comes into play, so let's get started!

Code of Ethics

An organizations code of ethics are used to shape the policies and guidelines of an organization. Ethics help keep us on the right track. Have you ever gone bowling and notices some lanes have "bumpers" that prevent the ball from going into the gutter? That's what ethics do for us, they keep us rolling down the lane and out of the gutter!

The CIA Triad

The CIA triad are the three supporting legs of cybersecurity and they are:

Confidentiality

Integrity

Availability

It's these three things that we must protect in order to ensure our organization stays secure.

Accountability, Privacy and Non-repudiation

An important aspect to cybersecurity is the ability to identity who has done what. We might see this in a system log or through other means and it's also very important to ensure data privacy. We don't want the entire world to read our emails so we use encryption to protect our data privacy and that's where this sections topics come into play.

Knowledge Check

We defined privacy as freedom from which of the following?

  1. AUnwanted intrusion
  2. BUnwanted invasion
  3. CUnwanted busy bodies
  4. DUnwanted eavesdropping

Security Controls

A main goal within cybersecurity is to control the outcome of various situations including things like attackers trying to break into our network or users clicking on things they shouldn't. In order to attempt to control the outcome of these situations we use security controls.

Knowledge Check

Controls are put in place to help control the outcome of an event.

Validation

It's time to put your newly acquired knowledge to the test.

  • Data backups are very important to an organizations survivability in the event of a security event. Your manager has tasked you with identifying two security controls your organization can implement to help ensure the availability of data backups. Take a couple of minutes and think about two security controls that would be helpful to ensure data backups are happening properly and are being protected from security threats.
  • When you have your two security controls identified play the video below to see if you came up with any security controls that I came up with. Maybe you outsmarted me and came up with something I didn't. We can always learn from each other!

Code of Ethics

0:00<v ->When it comes to certification bodies, those organizations</v>

0:03that issue certifications, and specifically

0:06within the information security realm,

0:08the ISC Squared Certifications, it is very important

0:12that you understand their code of ethics,

0:15because you'll be held to them.

0:17So let's jump in and talk about these ethics.

0:20So ISC Squared has a code of ethics.

0:23Now one question is, well, why do we have these?

0:26Well, we have these code of ethics to provide an expectation

0:32for those certified individuals' professional behavior.

0:37So in order to hold and maintain

0:39an ISC Squared Certification,

0:41you have to abide by the code of ethics.

0:45So your professional behavior must reflect those ethics.

0:50So let's go ahead and talk about what these are.

0:52We're starting with the code of ethics preamble, okay?

0:57And here it is, right here.

0:59It says, "The safety and welfare of society

1:01and the common good, the duty to our principles,

1:05and to each other requires that we adhere,

1:07and be seen to adhere to the highest ethical standards

1:12of behavior."

1:13So if you are going to become ISC Squared certified,

1:16you have to follow these code of ethics.

1:19So you must adhere to the highest ethical standards

1:22of behavior.

1:24And down here, therefore, strict adherence

1:27to this code is a condition of certification.

1:31So if you're not gonna adhere to the code, you don't agree

1:34to it, you cannot be certified, according to ISC Squared.

1:38And this is one of their certifications.

1:40They have several of them out there.

1:42So next up is the code of ethics cannons.

1:45These are the four cannons of the code of ethics.

1:49Number one here.

1:51Protect society, the common good, necessary public trust

1:56and confidence, and the infrastructure.

1:59So you're looking to protect society.

2:01You're protecting the common good.

2:04You're protecting public trust and confidence,

2:07and of course the infrastructure as well.

2:10So it's by practicing these ethics that we gain trust.

2:14We become recognized professionals

2:17who follow these codes of ethics.

2:20Number two, you must act honorably, honestly, justly,

2:26responsibly and legally.

2:28So it's all of these things together.

2:30So not only do you have to protect these items over here,

2:35we have to act in certain ways.

2:38Then number three, we need to provide diligent

2:41and competence.

2:43That is key here.

2:44Diligent and competent services to principals,

2:47that's our customers.

2:48We have to maintain competency.

2:51And that is one of the reasons that we have

2:54to achieve certain CPE requirements,

2:59which are continuing professional education,

3:03to show that we are maintaining our competency.

3:07And then lastly, the fourth cannon here,

3:10we need to advance and protect the profession.

3:14So what we're meaning here is, by advancing the profession,

3:18we're keeping up with changes in the environments,

3:22and in security, and we are protecting the profession.

3:26We're protecting the profession

3:28by maintaining our ethical actions.

3:32And we're performing number one over here,

3:35of course two, and three.

3:37We're protecting the integrity of the profession,

3:40so that when someone sees

3:41that you hold an ISC Squared Certification,

3:44that they know that you do these things.

3:46You adhere to these four cannons, and you practice ethics.

3:50And that is key here, because when someone says,

3:53I hold X certification, if it's from an organization

3:58who just gives out pieces of paper

3:59and they don't really care about anything else

4:01except making money,

4:03then that certification just doesn't hold as much value.

4:07Whereas ISC Squared, they require that you adhere

4:12to this code of ethics.

4:13They require that you keep up to date with your CPE's,

4:18that you're studying, and you're advancing yourself

4:21and the profession, and that you're acting honorably,

4:24honestly, and justly and legally.

4:27And by adhering to that, it means

4:30that those certifications carry with them greater value.

4:35And that's where, as a professional

4:37within the security industry, we really need

4:39to adhere to these ethics.

4:42And now we're moving on

4:43to our organizational code of ethics.

4:45We've discussed our ISC Squared code of ethics,

4:48time to talk about the ethics

4:50for the organizations that we're a part of.

4:52And the organizational code of ethics does something for us.

4:55It helps to define the organization's ethical guidelines

4:58and best practices for a couple of things.

5:02Number one is honesty.

5:05Number two is integrity.

5:08Number three is professionalism.

5:10And that's what our organizational code of ethics do for us.

5:12They help us to define ethical guidelines

5:15and best practices for our honesty, integrity,

5:17and professionalism.

5:18And these are going to be used

5:20to help shape some things within our company, okay?

5:23They're gonna be used to help shape our policies

5:27and guidelines.

5:28So we see that swings right over into our policies

5:32and guidelines.

5:33And really the key with organizational policies

5:36is this image down here.

5:38We have this balance going on.

5:40And that's what these code of ethics are supposed to do.

5:44Help us to balance conflicting needs of laws

5:47and regulations with the need for a business to succeed.

5:52And that's because many businesses face regulations

5:57and laws that they have to abide by.

5:58They need to be compliant with them.

6:00And sometimes those can make being successful

6:03in business, difficult.

6:04They can cost a lot of money.

6:06They can make things hard on us.

6:08But the thing is, when it comes

6:09to our organizational code of ethics,

6:11it's really there to also help us

6:13to balance these two things out,

6:16so that they can both coexist.

6:19And of course, if employees or folks

6:21in the organization are not abiding

6:23by these codes of ethics, well, it can result

6:26in repercussions such as employee termination.

6:29And nobody wants that.

6:31So here, we see that not only do we need to abide

6:34by the ISC Squared code of ethics,

6:36but of course also our organizational code of ethics

6:40as security professionals.

6:41And we need to understand the importance of these ethics,

6:44and understand the expectations

6:46that we practice ethical behavior.

6:48That's what this has been all about.

6:50I hope this has been informative for you,

6:51and I'd like to thank you for viewing.

The CIA Triad

0:01<v ->Today we're going to talk about the CIA Triad.</v>

0:05And no, this isn't the Central Intelligence Agency,

0:08although that would be fun, but it's a little bit different.

0:11So we're gonna talk about confidentiality, integrity,

0:14and availability, that is the CIA triad.

0:17So with no further ado, let's jump in and get started.

0:21So the CIA triad, what is it? Why is it important?

0:26Well, the CIA Triad, "TRI" meaning three, has three sides

0:31as we can see in this drawing.

0:32Confidentiality, integrity and availability,

0:37those are the three pieces of the CIA triad.

0:42Now why is this important?

0:43Because within cybersecurity and information security,

0:47we are working to ensure, that is key here,

0:51that it's kind of our job is to ensure this CIA triad.

0:55So what does this really mean?

0:58Well, it means we want to work to provide confidentiality,

1:02and work to provide integrity to our data,

1:06and the availability of our data.

1:09So let's go a little further now and talk about

1:12each of these individually and and kinda the role

1:15that they play in this triad.

1:18So we're gonna start off with confidentiality.

1:20We see Mr. Hush Hush down here.

1:23Now, when it comes to confidentiality,

1:25what we're trying to do is make sure that only those

1:29who are authorized to access our data can access it.

1:33That means those who are unauthorized,

1:36well we don't want those folks to be able

1:39to access our data.

1:40We want to keep it confidentiality, we want to restrict

1:43access to it.

1:44We want to use something called

1:46the premise of least privilege.

1:49And we're gonna dive into what this means more later on.

1:53But we're gonna practice something called "least privilege",

1:57meaning we provide the least amount of privilege necessary

2:01for someone to do their job.

2:03So if we have hundreds and hundreds of thousands of files

2:07and folders and directories and all of the wonderful

2:09resources that we have, we don't want to give everybody

2:13out there access to all of these things.

2:16Absolutely not. We want to remove that.

2:18We wanna say, this person needs access to only this.

2:21Maybe this person needs access to these things over here,

2:25and this one to a couple of these over here,

2:28but that's all that they need access to,

2:29that is least privilege.

2:31Now why is that important when it comes to confidentiality?

2:34Because, if everybody has access to everything, well then,

2:38well, there's no confidentiality at that point necessarily

2:41because we need to control who can have

2:43access to everything.

2:44We wanna make sure that those unauthorized individuals

2:48don't have access to any of the things

2:51that they shouldn't have access to.

2:52So really when we're talking about confidentiality,

2:54what we've been talking about here is something called

2:56access control.

2:58And there are several different types of access control,

3:01and we're gonna dive into those later on.

3:03But this all on this right side of the screen here,

3:07well, that's access control in a nutshell.

3:10What else can we use to provide confidentiality to our data?

3:15Well just think about this, if you send an email to someone,

3:18it's gonna go out across the internet.

3:21And what is out there on the internet?

3:23Well, there's lots of things on the internet.

3:25It goes through different service providers as it

3:27jumps through various networks to get from

3:30point A to point B to point C, and maybe finally down here

3:34to your destination where that user can open up the email

3:37and read the contents.

3:39Well, as your emails and other data traverse the wide world

3:44of the internet, which is the wild wild west out there,

3:48who's to say someone can't go out there,

3:52and take a look at your email?

3:54Well, because it's absolutely possible these emails are

3:57sent in plain text.

3:59So what can we do to combat this?

4:01Well, let me make a little room here.

4:04We can use something called encryption.

4:07So we have our email over here.

4:09What we're gonna do is we're going to use a key of some sort

4:12and we're going to encrypt this email so that anybody

4:17that doesn't have that key, they cannot read the email.

4:20So as it traverses the internet and all the different paths

4:24it may take before it gets to its final destination,

4:27anybody out here who doesn't have the key, they're not gonna

4:29be able to read that email, meaning we are going to maintain

4:32the confidentiality of the contents of that email.

4:35Hey, super cool.

4:37So then when it gets down here to its final destination,

4:40the user can take their key and they can open that email

4:44and read it and voila, there we go,

4:47we've achieved confidentiality.

4:49So there's a couple different pieces.

4:50We can use encryption to help with confidentiality,

4:53we can use access control to help maintain confidentiality.

4:58And why are we maintaining confidentiality

5:00in the first place?

5:01Because our data can be sensitive,

5:04it can have trade secrets in it.

5:06Maybe it has sensitive privacy information in it.

5:10We need to maintain control of our data, and part of that is

5:14maintaining the confidentiality of the data.

5:17So that's the C part of the CIA triad. What about the I?

5:21Good old integrity. There we go.

5:24So integrity. This is ensuring that our data is accurate.

5:30So why is our data not accurate?

5:33Did we mess something up? Did we miscalculate something?

5:36No, no, no, no, no, something totally different.

5:38This is dealing with making sure our data

5:41hasn't been tampered with.

5:44Because, just same example we used before

5:47when we were sending an email, if I go over here

5:50and I take an email and I send it out,

5:52and it goes out across the internet and through all the

5:54different routers and devices out there to get to

5:57where it's finally going through different service providers

6:00and such, and the user gets their email.

6:03And originally I was placing an order, so I want to order

6:07part number 1234,

6:09and I want to order a quantity of five.

6:12Okay? That's what was in my email.

6:15Well, if someone tampers with that email

6:18and they change that order to part number 6321,

6:24and a quantity of 500,

6:28well, that completely changes my order.

6:32And that is why we need to protect integrity,

6:35not to protect our orders necessarily,

6:37but sure, of course that's one example.

6:39But because we need to ensure that our data is accurate,

6:46we don't want it to be tampered with, we need to ensure

6:48the integrity of our data, and some different ways

6:52that we can do this, we can perform error checking.

6:56So for example, in this instance, if I use some type

7:00of mathematical equation to give me an output of

7:03what my original message equals, maybe it actually equals

7:08X, 3, 2, 6, 9.

7:11You know, in some mathematical equation,

7:13actually we call this hashing,

7:14and this value now represents the email.

7:17So I could actually attach this to the email,

7:21and then when it gets to the other side, we could run

7:24that mathematical algorithm again.

7:26And here it would equal Y, 3, 1, 1, 2.

7:31All right? So that's what that equals.

7:33So if I take my, out of this message X, 3, 2, 6, 9,

7:38does this value equal that value? Well the answer is no.

7:42So that means that our message was tampered with,

7:46and this is part of something like error checking.

7:48We're looking to see if our data was tampered with,

7:52and the integrity has been compromised of our data.

7:56And if you think about this is one example, right?

7:59But what about when it comes to medical information?

8:01Well, that could be very dangerous as you could imagine.

8:05If someone's medical records were tampered with

8:08and we didn't have the integrity of the data,

8:10well maybe something they were allergic to gets changed

8:13in their medical records and then they get a treatment

8:16and they have an allergic reaction, you see where

8:18this could go, this could be very dangerous.

8:21So again, we're looking to protect the integrity of our data

8:25and really one of the best ways we can do that is

8:28through an error checking or something we call hashing,

8:32which uses a mathematical algorithm to calculate a value,

8:36just like we looked at in this example.

8:38All right, so that's the "I" leg of our CIA triad.

8:41We've got one more to go, that is the "A" or availability.

8:46So here we're looking to make sure our data is, well,

8:49it's available, meaning we can use it.

8:53If our data is not available to us to use,

8:57well what good is it, right?

8:58We can't actually access it and use it.

9:00We've gotta have it available to us.

9:02So how can we, you know, protect our data

9:05and make sure it's available?

9:07Well, one of the things we can do is

9:08practice access control.

9:10Just like we talked about in our

9:13confidentiality, access control.

9:15If we allow unauthorized users to access our data,

9:21well, guess what?

9:22Those unauthorized users, whoa...

9:26Well, they could go out there and delete our data.

9:28Well then it's not available to us, or they could change

9:32the data and compromise its integrity.

9:34So then it's inaccurate.

9:35And if it's inaccurate, it's of no use to us,

9:38so again, it's affecting the availability.

9:40Another thing we could do is put some type of

9:43security controls in place to help

9:48protect our data, make sure it's available,

9:50because we got all those bad guys out there on the internet

9:54who might do something like cause an attack

9:56against our environment.

9:58And if they're trying to attack, maybe we can put something

10:01like a firewall out here, and that firewall

10:04is gonna help protect us.

10:06So this is a security control, something we put in place

10:09to control the situation.

10:11And it's related to security.

10:13So we could do a firewall,

10:14or maybe an intrusion detection system

10:18that we could put in place to analyze the traffic

10:21as it's coming through into our environment

10:23so we can help keep the bad guys out,

10:26making sure that our data is available.

10:29We can also build redundancy into our systems.

10:34So instead of running our data on one server,

10:37we actually spread the data across multiple servers in maybe

10:41a cluster so that if we lose one of those servers,

10:45we still have our data available to us.

10:48So redundancy, we could have redundant power.

10:50That's pretty important,

10:52because if the lights go out, well guess what?

10:54Our servers go down, our infrastructure goes down,

10:57we'd lose access or availability of our data.

11:01The same for our HVAC or air conditioning and ventilation.

11:05Because when we're dealing with lots of network equipment

11:08and servers and such, it generates lots of heat,

11:10and if it overheat, it's no longer able to function.

11:12Well, it affects the availability of the data

11:16on those devices.

11:18So it's very important that we have redundancy as part of

11:22protection for our availability.

11:25So those are the three things that make up the CIA triad.

11:30That's our confidentiality, our integrity,

11:33and of course our availability.

11:36That's the CIA triad.

11:37And that's really what we look to protect

11:40within information security.

11:43So we're looking to protect all of these things,

11:46because when we do that together,

11:48when we have all three legs of the CIA triad,

11:51well then, we are going to be winning at security

11:54and making sure our data is accurate and available,

11:58and kept confidential.

12:01I hope this has been informative for you,

12:02and I'd like to thank you for viewing.

Accountability, Privacy and Non-repudiation

0:00<v ->It's time to talk about accountability,</v>

0:03privacy, and nonrepudiation.

0:05These three things are very important

0:07when it comes to security.

0:09We need to have accountability and we need to have privacy.

0:12And then nonrepudiation is something

0:15that comes into play a little later on.

0:16But we're gonna discuss all these right now.

0:20And we're starting off with accountability.

0:22And it's very important that we have accountability.

0:25And accountability is holding someone accountable

0:30for their actions.

0:32And it's very important that we do this

0:34because without accountability, there are no consequences

0:38for not following things like code of ethics

0:42and policies and procedures

0:46and anything else laid out by the organization.

0:50So again, accountability, holding somebody accountable

0:53for their actions, very important.

0:55Because if we didn't have accountability,

0:58well then there's no reason for anyone

1:00to follow what's been laid out by the organization,

1:03like the code of ethics and policies and procedures.

1:06There's no consequences, no accountability.

1:09So it's very important that we have that.

1:12Otherwise, there would be no repercussions

1:14for not following these things.

1:15And at that point, there's really no incentive either,

1:19because if there's no repercussions, nothing's gonna happen.

1:22So you can really just do what you wanna do.

1:24That's why accountability is so very important.

1:27And next we're gonna talk about privacy.

1:30Now, according to Miriam Webster,

1:32privacy is freedom from unauthorized intrusion.

1:38And this is what we want for our personal data

1:41and our lives, right?

1:42Absolutely.

1:44We want freedom from unauthorized intrusion.

1:46If we want people to know our business,

1:48then we'll post it on social media

1:50or we'll tell somebody about it.

1:52But otherwise, we want our personalized, our data

1:57to be free from unauthorized intrusion.

1:59And the same goes for the data in our organizations.

2:03The data that our organizations manage.

2:05We want to keep it free from unauthorized access.

2:09And there are many laws

2:10and regulations surrounding data privacy,

2:13which we're gonna cover later on in this course.

2:15But for now, just to understand, privacy

2:18is freedom from unauthorized intrusion,

2:20and we want to keep our data private.

2:25Absolutely.

2:26We don't want unauthorized access to our data.

2:29All right, so that's accountability and privacy.

2:31Next up we're gonna talk about nonrepudiation.

2:34So it is a strange sounding word.

2:37So let's go ahead and break this down.

2:38We're gonna start with repudiation.

2:42Now, repudiation is the ability to say

2:46that you didn't do something.

2:49Okay?

2:50That's what repudiation means.

2:51Basically, you know, "I didn't send an email"

2:53or "I didn't open a file," so that is repudiation.

2:58But if we put non in front of that,

3:01so we have nonrepudiation, it means

3:05that you don't have the ability to say this, right?

3:10So let's talk about some of the examples of nonrepudiation.

3:14So when it comes to emails, if you have nonrepudiation,

3:19you can't say that "I didn't send this email."

3:24So as it goes out to its recipient over here

3:27and the recipient reads it

3:29and says, "Hey, did you send this email?"

3:31You cannot say, "I didn't do that."

3:34See, that's not an option with nonrepudiation.

3:37So we have proof that the person sent the email.

3:41Okay, what about accessing a file?

3:43Maybe making changes to the file?

3:46So we change a little bit in the file,

3:49and the question comes about,

3:51"Hey, who made the change to this file?

3:53Did you do that?"

3:54With nonrepudiation, the person can't say, "I didn't do it,"

3:58because we have proof that they did.

3:59So really, with nonrepudiation, we're looking to prove

4:04that someone did something.

4:06That's what it comes down to.

4:08But this isn't necessarily a bad thing.

4:10We're not looking to catch someone in a crime

4:13or something necessarily.

4:15It could be that you want to prove that you sent it.

4:17"See, I sent this file, I changed that file,

4:21I sent the email," whatever it is.

4:23So you can prove that you did.

4:24But how can this be done?

4:26Well, when it comes to proving that you sent an email,

4:30let's say, you could use something called PKI,

4:34and that is our Public Key Infrastructure.

4:39And this is dealing with encryption keys.

4:42So earlier we had talked about using encryption

4:44to encrypt an email to maintain its confidentiality.

4:48So if I take my key right here, and I go ahead

4:51and I use that key to digitally sign my email,

4:57which basically means you take the key

4:59and it runs that hashing algorithm

5:01that we talked about earlier,

5:02and it puts that data into the email.

5:04So since you are the only one who has access to this key,

5:09it's your private key, you hold it safe,

5:12and you don't let anybody else have access to it.

5:14That way when this email goes out

5:16and you've digitally signed it, you can say, "I sent it."

5:22And you have proof because you signed it with, that's right,

5:26your key right there.

5:28So that is an example of nonrepudiation.

5:31You want to prove that you sent it.

5:33And since you're the only person on earth who has access

5:35to that private key, you can prove it.

5:38You've digitally signed it.

5:40And we can sign files as well.

5:42You can sign various objects,

5:45but again, oftentimes we use PKI,

5:48or Public Key Infrastructure, with our private key to sign

5:52a piece of data to prove

5:55that you did something with it.

5:56And that is all about nonrepudiation.

5:59You wanna make sure that you can prove

6:01that you did something with some digital assets, like files.

6:05And again, also it could be the other way.

6:08So if you're looking to see if someone did something,

6:11you can find out again by nonrepudiation.

6:15I hope it's been informative for you

6:16and I'd like to thank you for viewing.

Least privilege & Segregation of Duties

0:01<v ->Within information security, we're always trying</v>

0:03to control the security of our environment.

0:07We're protecting the CIA triad. We're protecting our assets.

0:11And one of the ways that we do this is we practice

0:14some things like least privileged and segregation of duties.

0:19These are two ways that we can control access

0:21that people have to our assets.

0:23We don't want them to have too much access

0:25because then they could do nefarious things

0:28and we don't want that to happen.

0:29So let's jump in and talk about these.

0:32So let's talk about principle of least privilege.

0:34The idea is you should only be provided

0:37with enough access to do your job and no more.

0:42Now, it is very important that we are given enough access

0:46to do our job, otherwise we wouldn't be able to do it.

0:49And that is detrimental to the organization, right?

0:53It hurts the organization if people can't do their job.

0:56So we have to make sure they have enough permissions.

1:00That is key. Enough, but not too much.

1:06And that is the principle of least privilege,

1:10because if you give too much permission or too much access,

1:16well that's not good either,

1:18because then nefarious activities can be carried out.

1:23Just think about this, if in your organization you've got

1:26a thousand users in there and those thousand users

1:30have access to everything in your organization data-wise,

1:35well they don't need that access.

1:38And so if someone is feeling like they've been wronged

1:42by the organization, again, they have access to everything.

1:47So they would be able to go out

1:49and access sensitive information

1:53and take that information and maybe sell it to a competitor

1:57or leak it online, whatever it might be

2:00to cause harm to your organization.

2:02And that would be an insider threat.

2:05But we can prevent this from happening by practicing

2:09principle of least privilege.

2:11We only give people enough access to do their job, okay?

2:16That's where this comes into play.

2:18Now, let's talk about a couple of examples.

2:21Let's say we have an email administrator.

2:24So there is our email server here,

2:27and they are the email administrator.

2:29They manage all the email for our organization.

2:32Well, we need to make sure

2:34that they have administrative access into our mail server.

2:38Absolutely, that's how they do their job.

2:41But if I have over here, there we go, my accounting server,

2:46do I need to give the email administrator

2:48administrative rights or any permissions at all

2:51to my accounting server?

2:53Well, the answer is probably not, and I wouldn't want to.

2:57They don't need access to that, okay?

3:00And another example, I've got this help desk technician

3:03over here working away at the help desk,

3:06helping our folks out,

3:07and he's working on fixing end user problems, okay?

3:12So that means that he probably doesn't need any type

3:15of administration access to the servers over here.

3:21He needs to have access to our end user computer

3:25so he can help 'em out, alright?

3:26So these are examples of principle of least privilege.

3:32So again, the key is least privilege.

3:35I'm gonna drive this home. Least privilege.

3:38When users have too much privilege, they can gain access

3:40to data and services that they don't need access to.

3:47And that's where we can run into risks

3:50such as insider threats or damage from viruses.

3:55What, damage from viruses? Yes, absolutely.

3:58So let's say I've got a user over here

4:01and everybody has access to everything.

4:04So we've got all of our digital assets over here,

4:07all of our files and all of our servers are over here

4:11and all these things, right?

4:12If this user sitting right here has access to everything

4:18and he goes ahead and receives a phishing email,

4:21downloads it, and gets a virus, well,

4:24the way the virus works is it uses the permissions

4:28of the user logged into the computer.

4:31If the user has administrative permissions

4:33over everything, guess what?

4:35So does the virus.

4:37That means it can spread and infect everything.

4:40And this virus could be malware, it could be ransomware.

4:42Who knows?

4:43It's something that we don't want in our environment.

4:46And again, principle of least privilege.

4:49So if this user only had permissions,

4:53let's change this up here.

4:55If this user only had permissions in all these things

4:59to these files over here, well this malware, virus,

5:03or ransomware could only access those files.

5:05It couldn't access or do anything else

5:08to the rest of our resources.

5:09And that is ideal. That's what we're looking for.

5:13So not only does it protect against things

5:15like insider threats, it also protects against malware,

5:18viruses, ransomware, et cetera.

5:20So again, least privilege helps to protect our environment.

5:24And too much privilege introduces risk.

5:29And we've talked about risk before and managing risk

5:32and risk is something that we in information security

5:35are always looking to reduce.

5:38We need to keep a handle on risk.

5:41And one of the ways that we can do it

5:43is practice principle of least privilege.

5:46And yes, there's always going to be risk,

5:48but we need to manage our risk.

5:50We don't wanna let it run free.

5:52We wanna manage it when we have the opportunity to do so

5:55and to minimize it by doing things such as,

5:58again, practicing principles of least privilege.

6:02And now onto segregation of duties,

6:04also known as separation of duties,

6:09is the idea that we don't want any one person

6:11to have too much authority so they can carry out

6:15a sensitive process all on their own, okay?

6:18Now, why would we want to do this?

6:20We wanna prevent someone from being able to take advantage

6:23of that situation.

6:25And let's go ahead and talk about some examples here.

6:28So one example is, think of accounting and payroll.

6:33Does the person who enters payroll data

6:36into the accounting system approve the paychecks?

6:40Probably not.

6:41Because if they did, let's say this person here,

6:45they entered the payroll information into the system

6:48and they approved the payroll so that the checks can go out,

6:53well, they could pay themselves or anybody else,

6:55whatever they wanted to, right?

6:56Absolutely. What's to stop 'em?

6:59Well, an auditor would catch them doing this eventually

7:03if auditing was being done.

7:04But by that time, it's already done.

7:07Alright, let's talk about another one.

7:08How about expense reports?

7:11With expense reports, does the person submitting

7:13the expense report also approve the expense report?

7:16Well, again, probably not,

7:18because if this person submitted an expense report

7:21and approved the expense report,

7:25they could expense anything they wanted to.

7:27A vacation. Hey, there you go.

7:30How about a vacation or a big old TV

7:32or something like maybe, I don't know, a boat or something.

7:35Who knows?

7:36They could put anything they wanted to

7:37on that expense report and approve it

7:39because they're the only ones seeing it.

7:41And again, you see what we're finding here

7:43is a single person having too much authority or permissions

7:49and they're able to take advantage of a situation.

7:52And this is something we're trying to avoid.

7:54That's why we have segregation of duties.

7:57Now, these are a couple examples of non-IT systems.

8:01What about examples when it comes to IT systems?

8:04Well, let's talk about data backups.

8:07That is a very important job.

8:11And if we have a backup admin over here,

8:14so this is our backup admin who is in charge

8:21of doing all the backups and performing test restores

8:24and making sure that everything with our backups

8:26is working successfully.

8:29Hey, that's great.

8:30Now, but what about when it's time to audit these backups?

8:34Because we should be performing audits, okay?

8:38And that's because we wanna make sure

8:40things are being done properly.

8:41We want to ensure that our backups are successful,

8:44that we are actually doing test restores.

8:47These are all things we should be doing,

8:49and that's what the audits are there to ensure

8:51are being done.

8:52However, if the backup admin takes care of things

8:56like the backups, okay, and test restores,

9:01and we want to audit this to make sure they're being done,

9:04would I assign the backup admin as the auditor for this?

9:08Well, no, I wouldn't because then the person doing the work

9:12is the one auditing the work.

9:14And that is a conflict of interest.

9:18And that's why we need to ensure it is someone else,

9:21maybe a third party.

9:23So it's someone other than the backup admin,

9:26it could be even somebody who's not in IT.

9:29And that's because we need to ensure

9:32that these backups are being done properly

9:35and our test restores are being done properly as well.

9:38And that requires someone else performing the audit.

9:42We don't want the same person auditing the work

9:44that they are doing.

9:45That just does not make sense.

9:47That's known as a segregation of duty. We segregate that.

9:51You got the person doing the work over here

9:54and you've got the third party auditor over here.

9:58And that's a prime example of using segregation

10:01of duties within IT systems, alright?

10:04So this is why we practice segregation of duties.

10:07It's important to information security and it helps us,

10:11that's right, reduce risk.

10:13Because if you think about it, if you've got

10:15that backup admin over here doing the backups

10:18and they're not doing the backups properly,

10:21our backups are failing and we're not doing test restores.

10:26We don't even know if the restores are gonna work.

10:28If we do not audit and find this out, guess what?

10:32When there is a problem, we have a serious incident

10:37on our hands because the risk is through the roof.

10:41Because we're not auditing,

10:42we're not finding these things out,

10:44and we're gonna be up the creek without a paddle.

10:47And that is not a place you wanna be my friends.

10:50So again, we're reducing the risk of our own personnel

10:54taking advantage of situations to gain something.

10:57So if we practice the segregations of duties,

11:00it's gonna help us make sure that this doesn't happen

11:03and it's going to lower our risk.

11:07Absolutely jump for joy. (laughs)

11:10All righty, so that is segregation of duty.

11:12I hope it's been informative for you

11:13and I'd like to thank you for viewing.

Security Controls

0:01<v ->When we talked about risk, one of the ways</v>

0:03that we could deal with risk was to mitigate it

0:06or fix the risk.

0:08And one of the things we can do to fix a risk

0:11or kind of mitigate it

0:12and minimize its likelihood of happening,

0:16is to implement something called security controls.

0:18And that's what we're gonna talk about right now.

0:21So the question is, what are security controls?

0:24Well, security controls are safeguards and countermeasures

0:29that we can put in place to reduce risk.

0:34The security controls attempt to control the outcome

0:38of a specific event.

0:40And again, it's all about reducing risk.

0:44So let's spend a couple minutes talking about

0:46what kind of controls we could use in a day-to-day life

0:50to reduce risk.

0:51Well, do you have a security system like this here

0:56in your home or business?

0:57Well, you may, many of us do.

1:00And we use these to secure our home to prevent people

1:05from breaking in and stealing our goods.

1:07Because when they break in and the alarm goes off,

1:10it scares them away.

1:12Okay, and then it alerts us,

1:14hey, someone broke into your house, something's going on.

1:17You need to call the police. You know, take action.

1:19So this is a type of control to prevent theft of our goods.

1:25Another example right here, warning lights.

1:28So if you get into your vehicle and you start it up

1:31and you get a warning light on your dashboard

1:34in your vehicle, let's say, well guess what?

1:38There might be something wrong with your vehicle

1:39and you need to get it taken care of

1:41before it causes damage.

1:43So this is a type of preventative control.

1:47Or maybe you use credit monitoring

1:50to detect and prevent bad guys from using your credit

1:56to purchase various goods, right?

2:00Because it helps us to identify suspicious activities

2:03with our finances or credit.

2:05And these are kind of everyday controls that many of us use.

2:11So I'd say at this point we understand what controls are.

2:14You know, the role that they play in security.

2:16So let's talk about some ways to reduce risk associated

2:20with some specific threats.

2:22So let's play a game. Let's play match three and win,

2:26alright, so here's what we're dealing with.

2:29We have human error over here.

2:31We've got viruses and malware, insider threats,

2:35and a stolen laptop.

2:37And over here we have some controls that we can use

2:42to help prevent specific risks from happening,

2:46or at least reduce the risk associated with them.

2:49So let's start with human error over here.

2:51So with our human error,

2:54which of these controls over here on the right

2:57do you think would help us to reduce human error?

3:01So we have file permission.

3:02So those are permissions allowing authorized individuals

3:06to access files.

3:08We have, that's our file permission.

3:10We have drive encryption over here.

3:12So this is where we encrypt a hard drive

3:15and the data on it so that if the drive was stolen or lost,

3:20that the data on it would remain confidential,

3:23the bad guys couldn't get at it.

3:25Okay, then we have security awareness training over here,

3:28and this is where we train our users

3:31so that they can make good decisions

3:33and not make errors by clicking on things

3:35that they shouldn't or opening files that they shouldn't.

3:38Then we have endpoint protection.

3:40This is like your antivirus or your anti-malware

3:43or endpoint detection and response software

3:45that runs on our endpoints.

3:48It could be our servers and our laptops

3:49and our workstations that keeps viruses and malware at bay.

3:54So we're starting off with human error.

3:56Which one of these over here on the right would allow us

4:00to reduce the risk of human error?

4:02So what do you think about this?

4:04Well, file permissions aren't gonna prevent human error,

4:08nor is drive encryption.

4:09But security awareness training that is going

4:13to allow us to train our users so that they can understand

4:18the do's and don'ts of security

4:20and reduce the likelihood of human error.

4:23So there you go. Security awareness training.

4:25All right, that's the first one.

4:27Next up is virus and malware.

4:31So what are we gonna do with virus and malware?

4:34Well, security awareness training is out,

4:36we've already chosen that one.

4:37So let's see, file permissions, that's users accessing it,

4:41drive encryption, it's controlling access

4:44to our data on our drives.

4:46Okay, but endpoint protection, that was our anti-malware

4:49and antivirus.

4:50So there we go. Endpoint protection.

4:54Alright, let's talk about the next one.

4:56This is insider threats. Ooh.

5:00So when it comes to insider threats,

5:02would it be file permissions or drive encryption?

5:05Well, file permissions is going to allow us to

5:08practice access control so that our individuals,

5:12our employees and folks only have access to what they need.

5:15They don't have access to everything.

5:16So that would help protect against insider threat.

5:20There you go.

5:21And then last but not least,

5:23a stolen laptop right over here.

5:26So what are we gonna do to protect the data

5:28on a stolen laptop?

5:29Well, we only have one option left,

5:30and that's drive encryption.

5:32So let's go right over to drive encryption.

5:33And remember, if we encrypt our hard drive

5:36and someone steals the laptop with a hard drive in it,

5:38they're not gonna be able to read the data.

5:40So that is it. So match three and win, guess what?

5:43We matched four. I hope this has been informative for you,

5:46and I'd like to thank you for viewing.

Security Control Categories

0:00<v ->So now that we know what security controls are,</v>

0:03and we understand that we use them every day,

0:05even in our normal everyday lives,

0:08not only in information security,

0:10well, we're gonna focus now on the information security,

0:13based security controls,

0:14and more specifically, the three different categories

0:18that we use to categorize security controls.

0:20So let's get started.

0:22So when it comes to security controls,

0:24we have three main categories,

0:27and that is administrative, physical, and technical.

0:35Those are the three primary categories of security controls.

0:38And now, we're gonna dive into each one and discuss them,

0:40starting with administrative security controls.

0:44So starting off,

0:45we're talking about administrative security controls.

0:47Think of this as administrative,

0:50thinking of reports and paper is involved.

0:53You're writing things out and you're reading things, okay?

0:56We're not necessarily configuring firewalls or antivirus

1:00or putting out anything to help protect access to something.

1:04This is more based on things

1:07around administrative types of work.

1:09Now, for example, an audit.

1:12An audit would be a type of administrative security control.

1:16You got these two folks down here performing audit

1:19on some data.

1:20And another example is the reviewing of file permissions

1:26where we're checking people's permissions

1:28to make sure they only have the permissions that they need.

1:30Because within our organization,

1:32we've got lots of people that work there,

1:34and people change roles.

1:37They move to different departments.

1:39And the thing is, when they do this,

1:42well, their needs for permissions often change.

1:45So we may add permissions to some users,

1:48but oftentimes, we forget to take away permissions

1:50that they no longer need.

1:51So that's where file permission reviews come into play.

1:55We're really trying to make sure

1:56that we practice least privilege,

1:59like we previously discussed.

2:01Another type of administrative security control

2:03are policies.

2:04We've talked about policies,

2:05and along with policies come our procedures,

2:09and along with policies and procedures come standards,

2:13and these standards outline requirements

2:17that we want to follow.

2:18And we could document those

2:20within our policies and procedures.

2:23And then lastly, something called a baseline.

2:27Now, what a baseline is,

2:28is these are standard settings, so we'll put that down here.

2:32These are standard settings

2:35for various objects such as servers and workstations

2:38and smartphones and network devices.

2:40You know, the list goes on and on and on.

2:42Think of a baseline as a recipe, okay?

2:46So if you were to bake a cake and you followed recipe,

2:49and you know you put one cup of this

2:51and one teaspoon of this,

2:53and two tablespoons of this and four cups of this,

3:00and you put all these together,

3:01and out comes a wonderful cake

3:03that tastes absolutely beautiful.

3:05Okay, well, if you wanna reproduce that,

3:07you're gonna follow this same recipe.

3:09Well, that's what a baseline is

3:11when it comes to the devices within our environment.

3:15They're a group of standard settings.

3:18And we do this because when we deploy these devices,

3:21let's say we're deploying workstations,

3:23we want them to all be deployed the same way.

3:26And that's why we want to use a standard way of doing this.

3:30It ensures conformity and it reduces human error.

3:36Because if we have this baseline,

3:38and it's like a checklist here,

3:40where we've got all the things we need to do,

3:42when we deploy this workstation, let's say,

3:46we want to make sure that we join it to a specific domain.

3:49We wanna make sure that we configure certain settings

3:52on it, okay?

3:53We install antivirus on it.

3:54We do this to it, and we do that to it.

3:56That way, as we deploy multiple of these devices,

4:00they're all the same

4:03and they're meeting our organizational standards.

4:06And that's what a baseline is, that's what it does for us.

4:09And not just workstation, though.

4:11We're talking about servers and network devices

4:13and smartphones and tablets,

4:14and you know, the list goes on and on.

4:16It could be for anything that we deploy.

4:18So that's the baseline.

4:19So there you go.

4:20Those are some different examples

4:22of our administrative security controls.

4:24Let's talk about auditing and file permission review,

4:28and, of course, policies, procedures, standards,

4:30and baselines as well.

4:33So that's our administrative security controls.

4:36Next is our physical security controls.

4:38And think of this as physically protecting our assets.

4:43So when it comes to this,

4:44we might use something like a man trap,

4:47or it may be called a person trap now.

4:51But the idea here is that only one person can enter an area

4:56at a time.

4:57So like this person, goes ahead and types in this code here,

5:00and it goes into this contraption here,

5:03and the door closes and then the other side opens.

5:06But this way, only one person can enter at a time.

5:10You can't have two people in there.

5:12There's sensors in here that are checking

5:14to see if there's more than one person

5:15before opening the door on the other side.

5:18And this prevents something called piggybacking.

5:20And that's where one person will type in their code

5:24and they'll go ahead and walk in,

5:25and a second person will walk in before the door closes.

5:29Now, this man trap here, this prevents that.

5:32But if you think about a general building,

5:35and it's got a door there and maybe a keypad here,

5:37and somebody types in their digits

5:39and their door opens and they walk in,

5:41well, somebody coming up behind them can catch the door

5:44before it closes and let themselves in

5:47without putting their code in,

5:48and that's known as piggybacking.

5:49And that's what a man trap or a person trap prevents.

5:52Well, you know what else can help secure our building

5:56would be a guard, like this here.

5:58The guard's gonna sit there

5:59and make sure the only authorized personnel can come in.

6:02Another option would be security badges.

6:05So we've got a badge here, and it may be a proximity badge.

6:09And those are badges that when you have a badge reader

6:13outside of a door,

6:14you hold it up to the badge reader

6:15and it reads your credentials on there and it lets you in.

6:19Other examples of physical security controls

6:21would be fences.

6:22So you may have fences outside your building

6:25and maybe there's even some razor wire across the top

6:27because you have sensitive material inside

6:29and you wanna protect it.

6:31It could be lots of different things.

6:33It could be on the driveway going into the building.

6:36Maybe in front of the building,

6:38there are these little pylons

6:39that are there and they're metal

6:41so that you can't drive into the building,

6:43and they protect access into the building.

6:46And it could be a receptionist

6:48that's sitting in the building,

6:49could be lots of different things.

6:50So what we're talking about is physical security,

6:53and all of these are examples of that.

6:56And lastly, we're gonna talk

6:57about technical security controls.

6:59Now, this is where we're thinking about configuring things

7:01like firewalls and antivirus, and so on and so forth.

7:04So these are technical devices

7:07that help protect our digital assets,

7:10such as here, we have a firewall as an example, absolutely.

7:15We could have an intrusion prevention system.

7:18That's going to analyze data

7:19as it comes into our environment

7:21and check its digital signature to see if it is malicious.

7:25And if it is, well, it will stop it from entering,

7:28and that's what an IPS does.

7:30We also have encryption

7:31because we encrypt our data

7:34to protect it from unauthorized access.

7:37People can't read it

7:38if they don't have the proper encryption keys

7:40to decrypt and read that data.

7:42We also use things like session timeouts.

7:46And this is where you have a computer

7:47and you're sitting there working on something,

7:49and you get up and walk away to go get a snack or something,

7:53and you're over there chatting with somebody

7:54at the water cooler and you're gone for 15 minutes.

7:57Well, maybe after five minutes of inactivity,

8:01your screen locks

8:02so that you have to reenter your credentials

8:05before you're able to gain access to the computer again.

8:08So that would be like a session timeout.

8:10We could also use password aging or password rotation,

8:15and this is where once your password reaches a certain age,

8:18could be 90 days,

8:20or let's say it could be 180 days, whatever it might be.

8:23Within your company's policies,

8:25you're going to have to change your password

8:27every so many days.

8:29And again, that's to prevent us

8:30from keeping the same password for years on end,

8:33which increases the risk of that password being compromised

8:37or exposed in some way.

8:39And then lastly, along those same lines is account lockouts.

8:43So if we have, let's say, five failed login attempts

8:48within a 10-minute period,

8:51well, maybe the account locks out

8:53and you have to call the help desk to get it unlocked.

8:54And what this does is helps prevent

8:56against brute force login attacks,

8:59trying to guess people's passwords.

9:01So again, account lockouts are definitely another type

9:04of technical security controls.

9:06So that is our technical security controls.

9:09So again, we talked about the administrative security

9:13controls, our physical security controls,

9:16and lastly, our technical security controls.

9:19And those are the three different categories

9:20and some examples of each of them.

9:23I hope this has been informative for you,

9:24and I'd like to thank you for viewing.

Other Security Concepts

0:00<v ->All right, we're gonna wrap up this series of Nuggets</v>

0:04by discussing some other security concepts,

0:07such as performing periodic assessments,

0:10carrying out audits,

0:11and something called due diligence and due care,

0:14and we'll discuss what those are and how they differ.

0:17So with no further ado, let's jump in and get started.

0:20All right, so we're gonna start off

0:22by talking about assessing compliance.

0:24And within many fields of business,

0:27there are needs to comply

0:28with regulatory standards and laws.

0:32For example, if you produce a product,

0:34and during that process of creating that product,

0:37you end up with some wastewater.

0:39So say, we've got a barrel of wastewater here.

0:42Well, we can't simply go and pour it down the drain.

0:45That's just not acceptable according to the EPA

0:48or Environmental Protection Agency here in the US.

0:52So what are we gonna do with it then?

0:53Well, I don't know.

0:54We gotta figure out what the EPA says we need to do with it.

0:56And again, this goes back to standards and laws.

0:59And no matter what area of business that you're in,

1:03whether you're in financial or you're in aerospace

1:06or you build widgets, really doesn't matter,

1:08most times, we have to abide by some type of standard

1:12or law.

1:12So most companies will need to comply

1:15with some sort of rules and regulations

1:17in order to ensure a company is conforming

1:18with those laws and regulations.

1:21And oftentimes, we perform a self-assessment,

1:25and that's where we go and we take a look

1:26at those standards and laws that we need to comply with

1:29and we go through and check off to see how we are doing.

1:33And so we'll have someone inside the organization do that.

1:36That's why it's called a self-assessment.

1:38Generally, it's not someone from outside the organization

1:40that comes in and does an assessment like this.

1:42And we do this to make sure that we are in compliance,

1:46we're meeting the requirements of the laws and standards

1:49that are put forth.

1:51And when we do these, the cost of it is relatively low,

1:55and that's because we're using internal personnel,

1:58and they're already familiar with what we do as a company,

2:01and we don't have to provide them access.

2:03They already have the access.

2:04So that's where that low cost comes into play.

2:07Now, one of the other things

2:09other than standards and laws and regulations

2:11that we should be assessing are our security controls.

2:16We need to go through our security controls

2:18that we have in place,

2:19and we need to perform assessments

2:21to make sure that those security controls are performing

2:24as they should.

2:25They're providing us the protection that we need from them.

2:29So that is assessing our compliance.

2:31Next step, we're gonna talk about periodic audits

2:34and reviews.

2:35Now, an audit is more of a formal assessment of compliance,

2:41and it could be compliance with a specific standard or law,

2:44or it could be an audit of our security controls,

2:48either way.

2:49And generally, this is going to be an outside person.

2:52So someone from outside of organization,

2:54and they are gonna come in and perform our audit for us

2:59and let us know how we're doing.

3:00And when we're auditing security controls,

3:03there's something that we need to talk about.

3:05So let's put those security controls back up here.

3:08When we're auditing against our security controls,

3:11we need to have something known as a baseline.

3:15And a baseline, when it comes to auditing

3:17and security controls,

3:18is going to be data showing how that security control works.

3:23So for example, if we had a firewall here,

3:26let's just draw out a little firewall.

3:28And a baseline for a firewall would show

3:30what ports or IP addresses are allowed to go

3:35through the firewall.

3:37And that way, we could test it.

3:39I could take an IP address that's not supposed to be allowed

3:42through the firewall,

3:43and I could try to access it.

3:45And if it's not able to go through,

3:46then I would know

3:47that security control is functioning properly.

3:50And then I would want to pick one that is allowed through,

3:53and I'd wanna test it

3:54to make sure that that security control is allowing in

3:56that through as it should.

3:58But you'll see here,

3:59if I as an auditor come in and I need to test something,

4:02I need to have something that tells me

4:04how that is supposed to work, and that is the baseline.

4:08Because if I don't know how it's supposed to work,

4:10then how do I know if it is going to pass or fail the audit?

4:16And the IT team is going to provide that baseline

4:20to the auditor.

4:21And they're also gonna have to provide the auditor access

4:23into whatever they need access to

4:25in order to perform their auditing.

4:27So there is a higher cost when it comes to an audit,

4:30generally, because we're dealing with an outside individual

4:33that has to be paid accordingly, as well as our IT staff.

4:37They have to provide them access

4:39and create and provide a baseline for them

4:41so they can perform the audit.

4:43And there is an added bonus when it comes

4:46to having an outside individual perform the audit,

4:50and that is that that person has nothing to gain

4:54from a control working properly

4:57or not working properly, right?

4:59Whereas if we had an internal person performing this audit,

5:02they may feel pressures from the board

5:05or from their managers or from whoever it is

5:08to say that everything is working hunky-dory, right?

5:11Absolutely, there could be internal pressures like that,

5:14but an outside individual

5:16most likely isn't gonna have those pressures.

5:18So you're more likely to get an honest review

5:22of your security controls

5:23and compliance with laws and regulations.

5:26So that's our periodic audit and review.

5:29And next up, we're gonna talk about due diligence.

5:33Now, what does that mean?

5:34Well, what due diligence really comes down to

5:37is putting forth the effort to understand your information,

5:43your organization, your information security policies,

5:47procedures, and knowing your environment.

5:49So it comes down to a really a key word, understand.

5:53I'll put in here also, know, to know.

5:56So really, due diligence is the effort you put forth

5:59to understand, to learn about,

6:02to know about your organization or what you're protecting,

6:06such as your data.

6:07What type of data are you working with?

6:10Or types, I could put in here,

6:12because there's multiple types of data.

6:14What laws surround your data?

6:17Where your data is located?

6:20These are all things that you need to know about your data,

6:24and that is due diligence.

6:25Due diligence is putting forth the effort,

6:28again, to understand, to know,

6:30to learn about what you are responsible for.

6:33And here, we're talking about data.

6:36So that's due diligence.

6:37Let's talk about due care.

6:39Due care is a little bit different.

6:42Due care comes down to action.

6:47Due diligence was all about learning

6:49and knowing and understanding.

6:51But due care is about what actions you take to do something,

6:56like monitor your data,

6:59to protect your data so that if there is an incident,

7:03you are able to manage your data

7:05and make sure it's available and protected.

7:08Now, when it comes to due care and due diligence,

7:10this isn't only information security-related.

7:13This comes down to everything in your organization.

7:16But we're talking about data and protecting our data.

7:19So if we talk about due care of data protection,

7:22we would wanna make sure that we're monitoring,

7:24we're protecting it.

7:25We have firewalls, we have other kinds of things.

7:28We have endpoint security.

7:30We're performing backups of our data.

7:34We're managing access control for our data.

7:38And these are types or examples of due care

7:41when it comes to managing data.

7:43So again, due care is all about action.

7:46Now, let's take an example here

7:48of due diligence versus due care,

7:51and this is all about owning a dog.

7:55So over here, we have a Wikipedia down here.

7:59So this is using a Wikipedia to learn about something.

8:04Over here, it looks like we're doing some researching

8:06and asking questions.

8:07So here, obviously, we're not doing a whole lot

8:11other than research.

8:13All right, so we're learning over there.

8:15And then over here, we have a dirty dog

8:17that needs to be cleaned.

8:18We need to take our dog for a walk,

8:19and we need to make sure the dog doesn't get into trouble.

8:22So over here, these are more action items.

8:25So over here, we have learning.

8:27And over here, we have actions.

8:30Now, which is due care and which is due diligence?

8:34Well, due diligence was putting forth the effort

8:37to understand or learn about something.

8:40So obviously, due diligence is this activity down here,

8:45whereas due care was all about action.

8:48So that goes right over here into our action.

8:51So there's a good example of due care versus due diligence.

8:55I hope this has been informative for you,

8:56and I'd like to thank you for viewing.

Validation

0:00<v Instructor>It's validation time,</v>

0:01and we're gonna validate the information

0:04that you learned during this skill,

0:05and we talked about security controls,

0:08and here your manager assigned you a task

0:10coming up with two security controls

0:12that you can implement at your organization

0:14to help protect your data backups.

0:15So what two did you come up with?

0:17I'm gonna go through the four

0:18that I came up with very quickly.

0:21The first one is going to be an audit or assessment.

0:26Performing audits and assessments would help us make sure

0:29that data backups are being performed

0:31and according to the way they're supposed to be performed,

0:34whether it's every night or every other day,

0:37just depending on what's going on in the organization.

0:40So an audit or assessment, that's a great thing to do.

0:43Next would be performing a test restore.

0:47So we got our little scientist over here

0:49doing some type of experiment.

0:51The idea is we wanna take our backup data there

0:54and we want to restore it somewhere

0:56to make sure that our backup applications

0:58and procedures are working properly

1:00so that we know when it's time to restore

1:02if we need to for some reason that we can.

1:04Another one would be to store backups offsite.

1:09And the idea here is maybe we have all of our data over here

1:12and we wanna back it up to the cloud or to another location.

1:16That way if there's some type of breakout,

1:18whether it's ransomware or some type of infection,

1:20and it infects our local storage,

1:22well, it's not going to infect our offsite backups.

1:26So keep that in mind. That's a good option there.

1:29And then lastly, we're gonna go back

1:31to our administrative types of security controls.

1:35And we're talking about mandatory vacation.

1:39That's right, if our IT folks have to perform

1:42or experience or enjoy, let's put it that way,

1:45a mandatory vacation, somebody else fills in for them,

1:47and again, we're getting a second set of eyes

1:49on the backend at that point in time.

1:51So those are four different types of security controls

1:55that we could implement to make sure

1:56that our backups are being performed correctly,

1:59that our backup procedures work correctly,

2:02that our software and hardware's working correctly,

2:05and that we're protecting our backup data

2:08from security threats.

2:10So there you go. Hopefully you had at least one of these.

2:13If not, cool. You know what?

2:14There's lots of different controls you can implement.

2:17These are just a couple of them

2:19for us to take a look at and discuss.

2:21Congratulations on finishing out the discussing ethics

2:25and security concept skill.

2:27I hope this has been informative for you,

2:29and I'd like to thank you for viewing.
