Book Description

Snort, an open-source intrusion prevention system (IPS), capable of real-time traffic analysis and packet logging, is regarded as the gold standard in IDS and IPS. With the final public beta for Snort 3.0 going live, you'll get your hands on an updated version of the Snort IPS that features a new design and a superset of Snort 2.X functionality, resulting in higher efficacy and improved performance, scalability, usability, and extensibility. The final release is expected in the latter part of 2024. This book helps you understand the fundamentals of packet inspection and the progression from intrusion detection to intrusion prevention. The chapters take you through the installation and configuration of Snort, focusing on helping you fine-tune your installation to optimize Snort performance. As you advance, you'll get to grips with creating and managing Snort rules, deploying Snort, tuning and thresholding, strategies for high bandwidth implementations of Snort, and so on. The examples in this book enable network administrators to understand the real-world application of Snort, while familiarizing them with the inner workings of Snort by analyzing the source code. By the end of this book, you'll be equipped to enhance the performance of Snort for even the largest and most complex networks.

What you will learn

• Understand the key changes in Snort 3.0 and troubleshoot common Snort 3 issues
• Explore the landscape of open-source IDS/IPS solutions, including Suricata and Zeek
• Write new Snort 3 signatures based on new threats and translate existing Snort 2 signatures to Snort 3
• Extend the functionality of Snort 3 by developing custom modules
• Write and optimize Snort 3 rules to detect and prevent a wide variety of threats
• Leverage OpenAppID for application detection and control
• Optimize Snort 3 for ideal detection rate, performance, and resource constraints

Who this book is for

This book is for network administrators, security administrators, security consultants, and other security professionals. Those using other IDSs will also gain from this book as it covers the basic inner workings of any IDS. Although there are no prerequisites, basic familiarity with Linux systems and knowledge of basic network packet analysis will be very helpful.
