Hacking Exposed: Network Security Secrets and Solutions Book

A lot of computer security textbooks approach the subject from a defensive point of view. "Do this, and you'll probably survive a particular kind of attack", they say. In refreshing contrast, Hacking Exposed, Second Edition talks about security from an offensive angle. A Jane's-like catalogue of the weaponry that black-hat hackers use is laid out in full. Readers see what programs are out there, get a rundown on what the programs can do, and benefit from detailed explanations of concepts (such as wardialing and rootkits) that most system administrators kind of understand, but perhaps not in detail. The book also walks through how to use the most powerful and popular hacker software, including L0phtCrack. This new edition has been updated extensively, largely with the results of "honeypot" exercises (in which attacks on sacrificial machines are monitored) and Windows 2000 public security trials. There is a lot of new stuff on electronic mail worms, distributed denial of service (DDoS) attacks and attacks that involve routing protocols.The result of all this familiarity with bad-guy tools is a leg up on defending against them. Hacking wastes no time in explaining how to implement the countermeasures--where they exist--that will render known attacks ineffective. Taking on the major network operating systems and network devices one at a time, the authors tell you exactly what Unix configuration files to alter, what Windows NT Registry keys to change, and what settings to make in NetWare. They spare no criticism of products they aren't impressed with, and hesitate not in pointing out inherent, uncorrectable security weaknesses where they find them. This is no mere rehashing of generally accepted security practices. It and its companion Web site are the best way for all you network administrators to know thy enemies. --David WallRead More
