Published Detection Engineering Lab
SOC Automation with Splunk
Simulates a credential-based brute-force attack by ingesting Windows Security Event Logs into Splunk, building SPL detection queries, and producing a structured analyst response workflow with documented triage decisions and measurable detection outcomes.
Scenario
Repeated failed logons indicate possible credential attack behavior.
Telemetry
Windows Security Logs reviewed and normalized inside Splunk.
Evidence
80+ failed logon attempts identified inside a defined time window.
Collect and normalize Windows authentication events for investigation.
Build SPL queries to group failed logon volume by source, user, and time.
Review correlated events, tune thresholds, and separate noise from signal.
Document analyst actions, escalation logic, and reusable case notes.
