Investigation Data Types: Access, Device, Server, Application, Authentication, Communication, and Audit Logs (4.8)

This episode explains the major log categories used during security investigations and how each source contributes part of the incident story. Access logs show who reached a resource and when, device logs reveal endpoint or network device activity, server logs show operating system or service behavior, and application logs provide details about application events, errors, transactions, or suspicious requests. Authentication logs help identify login attempts, failures, session activity, and identity abuse. Communication logs may show email, messaging, or network communication patterns, while audit logs preserve administrative actions and policy-relevant events. For Security+ scenarios, students should correlate multiple log types to confirm scope, timeline, affected accounts, and likely attacker behavior.
