The alert came without warning. A privileged account was transferring data far beyond its usual limits. No firewall caught it. No antivirus flagged it. This was an insider threat moving through secure remote access—the kind that hides within trusted channels.
Insider threat detection is no longer optional. Attackers, whether malicious employees or compromised accounts, exploit secure remote access systems because they bypass the perimeter. VPNs, SSH tunnels, and privileged access management tools give them precisely what they need: encrypted paths into core systems. Without continuous behavioral monitoring, these paths remain invisible to conventional security controls.
The foundation of effective insider threat detection is end-to-end visibility. Monitoring user behavior in secure remote access sessions means tracking keystrokes, file transfers, and authentication events in real time. You need baselines on normal activity and automated alerts for deviations. This is not about collecting massive logs—it’s about precise, actionable signals.
