performing-insider-threat-investigation
Investigates insider threat incidents involving employees, contractors, or trusted partners who misuse authorized access to steal data, sabotage systems, or violate security policies, combining digital forensics, user behavior analytics, and HR/legal coordination to build an evidence-based case. Use when DLP alerts flag large data transfers to personal cloud storage or USB devices, when UBA detects anomalous access patterns for a user account, or when investigating employee data theft, privilege misuse, or internal threat detection requests.

# Performing Insider Threat Investigation
## When to Use
- DLP (Data Loss Prevention) alerts on large data transfers to personal cloud storage or USB devices
- User behavior analytics (UBA) detects anomalous access patterns for a user account
- HR reports a departing employee suspected of taking proprietary information
- A privileged user is observed accessing systems outside their job function
- Whistleblower or coworker report alleges policy violations or data theft
**Do not use** for external attacker investigations where compromised credentials are used without insider collusion; use standard incident response procedures instead.
