Overview

If you are a network administrator, you're under a lot of pressure to ensure that mission-critical systems are completely safe from malicious code, buffer overflows, stealth port scans, SMB probes, OS fingerprinting attempts, CGI attacks, and other network intruders. Designing a reliable way to detect intruders before they get in is an essential—but often overwhelming—challenge. Snort, the defacto open source standard of intrusion detection tools, is capable of performing real-time traffic analysis and packet logging on IP network. It can perform protocol analysis, content searching, and matching. Snort can save countless headaches; the new Snort Cookbook will save countless hours of sifting through dubious online advice or wordy tutorials in order to leverage the full power of SNORT.Each recipe in the popular and practical problem-solution-discussion O'Reilly cookbook format contains a clear and thorough description of the problem, a concise but complete discussion of a solution, and real-world examples that illustrate that solution. The Snort Cookbook covers important issues that sys admins and security pros will us everyday, such as:

  • installation
  • optimization
  • logging
  • alerting
  • rules and signatures
  • detecting viruses
  • countermeasures
  • detecting common attacks
  • administration
  • honeypots
  • log analysis
But the Snort Cookbook offers far more than quick cut-and-paste solutions to frustrating security issues. Those who learn best in the trenches—and don't have the hours to spare to pore over tutorials or troll online for best-practice snippets of advice—will find that the solutions offered in this ultimate Snort sourcebook not only solve immediate problems quickly, but also showcase the best tips and tricks they need to master be security gurus—and still have a life.

Snort Cookbook 4 out of 5 based on 0 ratings. 1 reviews.

The core of this book is the chapter on Rules and Signatures. Snort is renowned for its rule language and its vast flexibility. It is a reasonably high level 'script' that seems more declarative than procedural. Ok, I'm speaking a little figuratively, but if you scan the rules, you might see what I mean. The chapter explains how to build rules of varying levels of complexity, depending on your needs. One neat trait is the profuse range of options for detecting traffic around the machine running Snort. Of course and inevitably, the default rules base has grown and it is regularly updated. Currently, these defaults number some 3000, and few sysadmins have the expertise to understand all of them. So one recipe tells you how to get and run an updater program (Oinkmaster). Though you are cautioned about letting it change your rules automatically. Other recipes expand upon the rule scope in interesting ways, like looking for p2p or Instant Messaging traffic. You might be responsible for a corporate network that bans these, perhaps. Here is a simple way to show a supervisor how you can stay on top of the problem.
