Secure your Linux network by thinking like an attacker

Evolving Web technology and new software releases make online security more challenging than ever. The number of hackers--both sophisticated crackers and script-kiddies--is growing constantly, and it's just a matter of time before your network becomes a target. Hacking Linux Exposed, Second Edition shows you, step-by-step, how to proactively defend against the latest Linux-specific attacks by getting inside the mind of today's most devious hackers. You'll learn how intruders gather information, specify targets, exploit weak spots, and gain control--usually while remaining undetected. Read case studies about both common and little-known break-ins, tips on how and why they occurred, and detailed countermeasures against these attacks.
