An account logs in at 3:07 a.m. from a location it has never used before. Files are accessed, permissions tweaked. No alarms trigger. This is how insider threats begin—quietly, inside your own ingress points.
Ingress resources are the gates to your systems. They route requests, control access, and define what the outside world can touch. When an insider with legitimate credentials decides to exploit those routes, traditional boundary defenses fail. Detecting this requires more than firewall rules. It demands visibility into access patterns, real-time audit trails, and behavioral baselines tuned for your environment.
Insider threat detection is about spotting shifts in normal ingress behavior. Look for changes in request paths, spikes in resource access, and authentication events that break the usual rhythm. Combine ingress resource logging with anomaly detection models that learn what "normal"looks like over time. Use short-lived credentials, strict route definitions, and role-based policies to limit damage if something gets compromised.
