# Detecting Insider Threat Behaviors
## When to Use
- When proactively hunting for indicators of detecting insider threat behaviors in the environment
- After threat intelligence indicates active campaigns using these techniques
- During incident response to scope compromise related to these techniques
- When EDR or SIEM alerts trigger on related indicators
- During periodic security assessments and purple team exercises
## Detection Gaps & Validation
- **Network logs alone miss the highest-signal exfil.** SIEM-only hunting overlooks USB mass copy (Security 6416 PnP device, Microsoft-Windows-DriverFrameworks-UserMode 2003/2102), local printing, and photographing the screen. Add removable-media and DLP telemetry.
- **Personal-cloud exfil blends with sanctioned use.** Uploads to personal OneDrive/Gmail/Dropbox look like normal SaaS traffic on raw byte volume. You need a CASB/proxy with per-user behavioral baselines, not a global threshold.
