It’s easy to capture packets with Wireshark, the world’s most popular network sniffer, whether off the wire or from the air. But how do you use those packets to understand what’s happening on your network?
Updated to cover Wireshark 2.x, the third edition of Practical Packet Analysis will teach you to make sense of your packet captures so that you can better troubleshoot network problems. You’ll find added coverage of IPv6 and SMTP, a new chapter on the powerful command line packet analyzers tcpdump and TShark, and an appendix on how to read and reference packet values using a packet map.
Practical Packet Analysis will show you how to:
–Monitor your network in real time and tap live network communications
–Build customized capture and display filters
–Use packet analysis to troubleshoot and resolve common network problems, like loss of connectivity, DNS issues, and slow speeds
–Explore modern exploits and malware at the packet level
–Extract files sent across a network from packet captures
–Graph traffic patterns to visualize the data flowing across your network
–Use advanced Wireshark features to understand confusing captures
–Build statistics and reports to help you better explain technical network information to non-techies
No matter what your level of experience is, Practical Packet Analysis will show you how to use Wireshark to make sense of any network and get things done.
Applied Network Security Monitoring is the essential guide to becoming an NSM analyst from the ground up. This book takes a fundamental approach, complete with real-world examples that teach you the key concepts of NSM.
Network security monitoring is based on the principle that prevention eventually fails. In the current threat landscape, no matter how much you try, motivated attackers will eventually find their way into your network. At that point, your ability to detect and respond to that intrusion can be the difference between a small incident and a major disaster.
The book follows the three stages of the NSM cycle: collection, detection, and analysis. As you progress through each section, you will have access to insights from seasoned NSM professionals while being introduced to relevant, practical knowledge that you can apply immediately.
- Discusses the proper methods for planning and executing an NSM data collection strategy
- Provides thorough hands-on coverage of Snort, Suricata, Bro-IDS, SiLK, PRADS, and more
- The first book to define multiple analysis frameworks that can be used for performing NSM investigations in a structured and systematic manner
- Loaded with practical examples that make use of the Security Onion Linux distribution
- Companion website includes up-to-date blogs from the authors about the latest developments in NSM, complete with supplementary book materials
If you've never performed NSM analysis, Applied Network Security Monitoring
will help you grasp the core concepts needed to become an effective analyst. If you are already working in an analysis role, this book will allow you to refine your analytic technique and increase your effectiveness.
You will get caught off guard, you will be blind sided, and sometimes you will lose the fight to prevent attackers from accessing your network. This book is about equipping you with the right tools for collecting the data you need, detecting malicious activity, and performing the analysis that will help you understand the nature of an intrusion. Although prevention can eventually fail, NSM doesn't have to.
