Wireshark is the world’s most popular network sniffer that makes capturing packets easy, but it won’t be much help if you don’t have a solid foundation in packet analysis. Practical Packet Analysis, 3rd Edition will show you how to make sense of your PCAP data and let you start troubleshooting the problems on your network. This third edition is updated for Wireshark 2.0.5 and IPv6, making it the definitive guide to packet analysis and a must for any network technician, administrator, or engineer. This updated version includes two new chapters that will teach you how to use the powerful command-line packet analyzers tcpdump and TShark as well as how to read and reference packet values using a packet map. Practical Packet Analysis will introduce you to the basics of packet analysis, starting with how networks work and how packets travel along the wire. Then you’ll move on to navigating packets and using Wireshark for packet capture and analysis. The book then covers common lower-layer and upper-layer protocols and provides you with solutions to real-world scenarios like Internet connectivity issues, how to intercept malware traffic, and fighting a slow network. You’ll learn how to: *Monitor your network in real-time and tap live network communications *Recognize common network protocols including TCP, IPv4 and IPv6, SMTP, and ARP *Build customized capture and display filters to quickly navigate through large numbers of packets *Troubleshoot and resolve common network problems like loss of connectivity, DNS issues, and sluggish speeds with packet analysis *Understand how modern exploits and malware behave at the packet level *Carve out data in a packet to retrieve the actual files sent across the network *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 Whether you’re a budding network analyst in need of a headfirst dive into packet analysis or an experienced administrator searching for new tricks, look no further than the third edition of Practical Packet Analysis.

Applied Network Security Monitoring is the essential guide to becoming an NSM analyst from the ground up. This book takes a fundamental approach to NSM, complete with dozens of 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, it is your ability to detect and respond to that intrusion that 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 scenarios complete with sample data. If you've never performed NSM analysis, Applied Network Security Monitoring will give you an adequate grasp on the core concepts needed to become an effective analyst. If you are already a practicing analyst, this book will allow you to grow your analytic technique to make you more effective at your job. Discusses the proper methods for data collection, and teaches you how to become a skilled NSM analyst Provides thorough hands-on coverage of Snort, Suricata, Bro-IDS, SiLK, and Argus Loaded with practical examples containing real PCAP files you can replay, and uses Security Onion for all its lab examples Companion website includes up-to-date blogs from the authors about the latest developments in NSM

A detailed and complete guide to exporting, collecting, analyzing, and understanding network flows to make managing networks easier. Network flow analysis is the art of studying the traffic on a computer network. Understanding the ways to export flow and collect and analyze data separates good network administrators from great ones. The detailed instructions in Network Flow Analysis teach the busy network administrator how to build every component of a flow-based network awareness system and how network analysis and auditing can help address problems and improve network reliability. Readers learn what flow is, how flows are used in network management, and how to use a flow analysis system. Real-world examples illustrate how to best apply the appropriate tools and how to analyze data to solve real problems. Lucas compares existing popular tools for network management, explaining why they don't address common real-world issues and demonstrates how, once a network administrator understands the underlying process and techniques of flow management, building a flow management system from freely-available components is not only possible but actually a better choice than much more expensive systems.

"Network analysis is the process of listening to and analyzing network traffic. Network analysis offers an insight into network communications to identify performance problems, locate security breaches, analyze application behavior, and perform capacity planning. Network analysis (aka "protocol analysis") is a process used by IT professionals who are responsible for network performance and security." -- p. 2.
