Network security has become an important part of corporate IT strategy and safeguarding all the nooks and crannies of your network can be timely and expensive. This book provides information about how to use free Open Source tools to build and manage an Intrusion Detection System. Rehman provides detailed information about using SNORT as an IDS and using Apache, MySQL, PHP and ACID to analyze intrusion data. The book contains custom scripts, real-life examples for SNORT, and to-the-point information about installing SNORT IDS so readers can build and run their sophisticated intrusion detection systems.SNORT is your network's packet sniffer that monitors network traffic in real time, scrutinizing each packet closely to detect a dangerous payload or suspicious anomalies.NSS Group, a European network security testing organization, tested SNORT along with intrusion detection system (IDS) products from 15 major vendors including Cisco, Computer Associates, and Symantec. According to NSS, SNORT, which was the sole Open Source freeware product tested, clearly outperformed the proprietary products.

Intrusion detection is not for the faint at heart. But, if you are a network administrator chances are you're under increasing pressure to ensure that mission-critical systems are safe-in fact impenetrable-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 a vital but daunting challenge. Because of this, a plethora of complex, sophisticated, and pricy software solutions are now available. In terms of raw power and features, Snort, the most commonly used Open Source Intrusion Detection System, (Ids) has begun to eclipse many expensive proprietary Idses. In terms of documentation or ease of use, however, Snort can seem overwhelming. Which output plugin to use? How do you to email alerts to yourself? Most importantly, how do you sort through the immense amount of information Snort makes available to you? Many intrusion detection books are long on theory but short on specifics and practical examples. Not Managing Security with Snort and Ids Tools. This new book is a thorough, exceptionally practical guide to managing network security using Snort 2.1 (the latest release) and dozens of other high-quality open source other open source intrusion detection programs. Managing Security with Snort and Ids Tools covers reliable methods for detecting network intruders, from using simple packet sniffers to more sophisticated Ids (Intrusion Detection Systems) applications and the Gui interfaces for managing them. A comprehensive but concise guide for monitoring illegal entry attempts, this invaluable new book explains how to shut down and secure workstations, servers, firewalls, routers, sensors and other network devices. Step-by-step instructions are provided to quickly get up and running with Snort. Each chapter includes links for the programs discussed, and additional

Network security is not simply about building impenetrable walls—determined attackers will eventually overcome traditional defenses. The most effective computer security strategies integrate network security monitoring (NSM): the collection and analysis of data to help you detect and respond to intrusions.In The Practice of Network Security Monitoring, Mandiant CSO Richard Bejtlich shows you how to use NSM to add a robust layer of protection around your networks—no prior experience required. To help you avoid costly and inflexible solutions, he teaches you how to deploy, build, and run an NSM operation using open source software and vendor-neutral tools.You'll learn how to:–Determine where to deploy NSM platforms, and size them for the monitored networks–Deploy stand-alone or distributed NSM installations–Use command line and graphical packet analysis tools, and NSM consoles–Interpret network evidence from server-side and client-side intrusions–Integrate threat intelligence into NSM software to identify sophisticated adversariesThere’s no foolproof way to keep attackers out of your network. But when they get in, you’ll be prepared. The Practice of Network Security Monitoring will show you how to build a security net to detect, contain, and control them. Attacks are inevitable, but losing sensitive data shouldn't be.
