How to Automate Cisco Security Devices with Postman and Python Online Training

Manual security-device changes can slow response times and introduce inconsistent firewall or access-policy updates. IT Directors can assign this associate-level Cisco course to network security admins with roughly three to five years of Cisco security experience who need a structured path into automation with Postman, Python, and REST APIs.

Plan for about 13 hours and 18 minutes per learner. The course starts with development-environment setup, data formats, REST API fundamentals, and Postman before moving into Python basics and Cisco security automation tasks, including FMC access policies and Cisco ASA firewalls. For change management, Team Leads should align learners on approved lab or non-production workflows before applying scripts to production devices. CBT Nuggets Playlists can sequence this training for security teams, and Team Reporting helps Training Managers track completion across assigned learners.

IT teams complete this training to reduce repetitive manual work around Cisco security platforms and build a shared foundation for safer API-driven operations.

• Standardize development setup with VS Code and Python so security admins work from a consistent automation environment.
• Interpret and use XML, JSON, and YAML when exchanging configuration or operational data with APIs.
• Use Postman to test REST API requests, responses, parameters, and payloads before turning workflows into Python code.
• Apply automation concepts to Cisco security scenarios such as creating access policies in FMC and working with Cisco ASA firewalls.

For IT Directors, the practical value is a team that can test API interactions, understand payloads, and automate defined security-device tasks with less reliance on one-off manual changes.

Knowledge

• How network programmability and automation apply to Cisco security environments.
• How REST APIs use requests, responses, parameters, and payloads.
• How XML, JSON, and YAML structure data for automation workflows.
• Core Python concepts, including variables, data types, strings, control flow, Boolean logic, lists, tuples, dictionaries, and sets.
• How Postman supports REST API interaction and testing.

Ability

• Prepare a VS Code-based development environment for automation work.
• Build foundational Python scripts for security automation tasks.
• Test API calls in Postman before applying them through code.
• Work with API data formats commonly used by network and security platforms.
• Automate selected Cisco security platform tasks, including FMC access-policy creation and Cisco ASA firewall workflows.
