Episode 215: Anomalous Behavior Recognition (Domain 5)
from Certified: The CompTIA Security+ Audio Course Hosted by Dr. Jason Edwards
Cyber threats often hide in plain sight, masquerading as normal user activity until they trigger something unexpected—and that’s why recognizing anomalous behavior is such a valuable skill. In this episode, we explore how to identify risky, unexpected, or unintentional actions that may indicate insider threats, compromised accounts, or social engineering in progress. Examples include unusual file transfers, logins at strange hours, elevated privilege requests, or repeated access to sensitive resources outside normal job roles. We discuss how behavior-based tools like User and Entity Behavior Analytics (UEBA) establish baselines and detect deviations without relying solely on predefined rules. We also touch on the importance of cultural awareness, since not all anomalies are malicious—some reflect confusion, poor training, or misunderstood policy. Recognizing anomalies early can stop breaches before they escalate—and create opportunities for education and prevention.
