Extrusion detection is the process of identifing unauthorized activity by inspecting outbound network traffic. If a security consultant observes suspicious or malicious traffic leaving his customer's network, there's a strong possibility that internal systems are already compromised. During the last three years extrusion-centric processes and products have become popular. This chapter from Richard Bejtlich's Extrusion Detection: Security Monitoring for Internal Intrusions will help you learn how to use this powerful investigative technique to enhance your customer's awareness and security posture.
