Investigating Insider Threat Indicators

When to Use

Use this skill when:

• HR refers a departing employee for monitoring during their notice period
• DLP alerts indicate bulk data downloads or transfers to personal storage
• UEBA detects anomalous access patterns deviating significantly from peer baselines
• Management reports concerns about an employee accessing sensitive data outside their role

Do not use without proper legal authorization — insider threat investigations must be coordinated with HR, Legal, and Privacy teams before monitoring begins.

Prerequisites

• Legal authorization and HR referral documenting investigation justification
• SIEM with DLP, endpoint, email, proxy, and authentication log sources
• Data Loss Prevention (DLP) system (Microsoft Purview, Symantec, Forcepoint) with policy alerts
• Endpoint monitoring capability (EDR with USB/removable media logging)
• HR data feed providing employment status, notice dates, and access entitlements
• Chain of custody procedures for evidence preservation
