Intrusion Analysis Overview

Intrusion Analysis Overview introduces learners to the investigation mindset used in incident response, threat hunting, and SOC operations. The course explains the goals of intrusion analysis, common attacker behaviors, evidence sources, event timelines, and the process of connecting different signals into a clear and meaningful investigation story. Learners understand how analysts move from alerts and raw observations toward hypotheses, validation, and response decisions. The course also helps learners recognize how evidence from endpoints, networks, logs, and security tools can be reviewed together to understand what happened during a potential intrusion. This course supports CCNA Cybersecurity study and helps beginners understand how intrusion analysis fits into the broader security operations lifecycle, including detection, investigation, response, and continuous improvement.
