Advanced Network Understanding with Wireshark

Network outages and security investigations often stall when teams cannot interpret packet-level evidence consistently. Advanced Network Understanding with Wireshark gives network, security, infrastructure, and support teams a shared foundation for analyzing traffic across TCP/IP, IPv4, IPv6, TCP, UDP, ICMP, DNS, Microsoft protocols, Wireshark display filters, and advanced Wireshark workflows.

For an IT Director, this course fits early- to mid-career IT Practitioners who already support networks and need deeper troubleshooting capability. The time investment is about 10.5 hours per learner, making it practical for a focused upskilling sprint or phased team rollout. Team Leads can use it to standardize analysis methods before assigning packet-capture responsibilities in production environments, reducing reliance on a few senior specialists.

CBT Nuggets supports rollout through Playlists for structured assignment and Team Reporting so Training Managers can track completion and keep change-management visible.

IT teams complete this training to make packet analysis a repeatable operational skill instead of an ad hoc escalation path. The course maps directly to common troubleshooting and investigation scenarios where Wireshark helps teams see what is actually happening on the wire.

• Faster network triage: Teams learn the protocol foundations behind TCP/IP, IPv4, IPv6, TCP, UDP, and ICMP so they can interpret traffic patterns during connectivity issues.
• Cleaner DNS troubleshooting: Practitioners build DNS analysis knowledge that helps separate name-resolution problems from application or routing issues.
• More focused packet review: Wireshark display filters help teams narrow large captures to the traffic that matters, reducing time spent searching through noise.
• Better Windows environment visibility: Microsoft protocol coverage helps infrastructure and support teams analyze traffic common in Windows-based networks.

Knowledge

• Core Wireshark concepts and how packet analysis supports network troubleshooting.
• TCP/IP fundamentals and how they relate to real packet captures.
• IPv4 and IPv6 behavior at the packet level.
• The roles of TCP, UDP, ICMP, and DNS in network communication.
• How Layer 4 and higher-layer traffic appears during analysis.
• Microsoft protocol concepts relevant to Windows network environments.

Ability

• Review Wireshark captures with a structured protocol-analysis approach.
• Distinguish between traffic types such as TCP, UDP, ICMP, and DNS.
• Apply Wireshark display filters to focus investigations.
• Analyze IPv4 and IPv6 traffic during troubleshooting.
• Interpret packet-level evidence to support escalation, remediation, or root-cause analysis.
• Use advanced Wireshark topics as a foundation for deeper network and security investigations.
