Insider Threat Detection with Lnav

The alert appeared without warning. One log entry. One abnormal session. Then another. Patterns were forming. Lnav lit them up fast, stitching raw text into meaning before the breach could deepen.

Insider threat detection is not just about catching obvious red flags. It’s about revealing the silent moves inside your systems—privileged accounts misused, database queries that dig too deep, file access at strange hours. These are the signs insiders leave behind, buried in logs that others overlook.

Lnav turns scattered log files into an indexed, searchable timeline. You can filter, highlight, and correlate activity across sources—authentication logs, application traces, system events—without moving the data into another platform. This keeps detection fast and accurate, with minimal operational overhead.

By clustering related events, Lnav shows behavioral anomalies in context. A single login from a new location may be noise. A login, followed by rapid data extraction and privilege changes, is a clear indicator. Lnav lets you see that chain, in seconds.

Integrating Lnav into insider threat detection workflows adds depth to existing SIEM alerts. You can pivot from broad alerts to precise queries, finding the exact commands, IPs, and processes involved. This tight loop between detection and investigation is what stops insiders mid-action.

Efficient detection depends on visibility and speed. Lnav’s real-time viewing and query features make it possible to catch insider threats before they escalate. No guesswork. No blind spots. Just raw, connected data you control.
