This module explores the foundational principles of using Python for network automation and NetDevOps. You will learn to interact with network devices programmatically using libraries like Netmiko and NAPALM, replacing error-prone manual CLI tasks with scalable, idempotent scripts. From a cybersecurity perspective, automation is a critical force multiplier for both attackers and defenders. You will discover how to automate reconnaissance, enforce configuration baselines, detect configuration drift, and instantly remediate vulnerabilities across the entire network fleet, while implementing secure credential management and GitOps practices.
