Managing Security with Snort & IDS Tools


Book Description

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 links at the end of the book give administrators access to numerous web sites for additional information and instructional material that will satisfy even the most serious security enthusiasts.Managing Security with Snort and IDS Tools maps out a proactive--and effective--approach to keeping your systems safe from attack.

Practical Intrusion Analysis


Book Description

“Practical Intrusion Analysis provides a solid fundamental overview of the art and science of intrusion analysis.” –Nate Miller, Cofounder, Stratum Security The Only Definitive Guide to New State-of-the-Art Techniques in Intrusion Detection and Prevention Recently, powerful innovations in intrusion detection and prevention have evolved in response to emerging threats and changing business environments. However, security practitioners have found little reliable, usable information about these new IDS/IPS technologies. In Practical Intrusion Analysis, one of the field’s leading experts brings together these innovations for the first time and demonstrates how they can be used to analyze attacks, mitigate damage, and track attackers. Ryan Trost reviews the fundamental techniques and business drivers of intrusion detection and prevention by analyzing today’s new vulnerabilities and attack vectors. Next, he presents complete explanations of powerful new IDS/IPS methodologies based on Network Behavioral Analysis (NBA), data visualization, geospatial analysis, and more. Writing for security practitioners and managers at all experience levels, Trost introduces new solutions for virtually every environment. Coverage includes Assessing the strengths and limitations of mainstream monitoring tools and IDS technologies Using Attack Graphs to map paths of network vulnerability and becoming more proactive about preventing intrusions Analyzing network behavior to immediately detect polymorphic worms, zero-day exploits, and botnet DoS attacks Understanding the theory, advantages, and disadvantages of the latest Web Application Firewalls Implementing IDS/IPS systems that protect wireless data traffic Enhancing your intrusion detection efforts by converging with physical security defenses Identifying attackers’ “geographical fingerprints” and using that information to respond more effectively Visualizing data traffic to identify suspicious patterns more quickly Revisiting intrusion detection ROI in light of new threats, compliance risks, and technical alternatives Includes contributions from these leading network security experts: Jeff Forristal, a.k.a.
