Episode 35 — Build Endpoint Visibility: What to Log, What to Alert, and What to Trust
This episode builds a practical approach to endpoint telemetry and explains why the GSEC exam expects you to distinguish between “we have logs” and “we can investigate.” You’ll learn what high-value endpoint signals look like, such as authentication events, process creation, command execution, network connections, privilege changes, persistence modifications, and security control status. We’ll connect telemetry to alert strategy by showing why alerting on everything creates fatigue, while alerting on nothing creates blind compromise, and how baselines and context reduce noise. Scenarios include detecting credential theft through abnormal logon patterns, identifying malware via suspicious parent-child process chains, and verifying whether data exfiltration occurred using endpoint network and file access evidence. Best practices include centralizing logs, protecting integrity, correlating with identity and network data, and validating time synchronization so timelines hold up. Troubleshooting focuses on missing events due to misconfigured agents, conflicting tools, or log retention gaps that erase the most critical window of activity.
