Overcome Your Fastest-Growing Security Problem: Internal, Client-Based Attacks
Today's most devastating security attacks are launched from within the company, by intruders who have compromised your users' Web browsers, e-mail and chat clients, and other Internet-connected software. Hardening your network perimeter won't solve this problem. You must systematically protect client software and monitor the traffic it generates.
Extrusion Detectionis a comprehensive guide to preventing, detecting, and mitigating security breaches from the inside out. Top security consultant Richard Bejtlich offers clear, easy-to-understand explanations of today's client-based threats and effective, step-by-step solutions, demonstrated against real traffic and data. You will learn how to assess threats from internal clients, instrument networks to detect anomalies in outgoing traffic, architect networks to resist internal attacks, and respond effectively when attacks occur.
Bejtlich'sThe Tao of Network Security Monitoringearned acclaim as the definitive guide to overcoming external threats. Now, inExtrusion Detection, he brings the same level of insight to defending against today's rapidly emerging internal threats.
