Book Description

Ethereal is the #2 most popular open source security tool used by system administrators and security professionals. This all new book builds on the success of Syngress' best-selling book Ethereal Packet Sniffing.Wireshark & Ethereal Network Protocol Analyzer Toolkit provides complete information and step-by-step Instructions for analyzing protocols and network traffic on Windows, Unix or Mac OS X networks. First, readers will learn about the types of sniffers available today and see the benefits of using Ethereal. Readers will then learn to install Ethereal in multiple environments including Windows, Unix and Mac OS X as well as building Ethereal from source and will also be guided through Ethereal's graphical user interface. The following sections will teach readers to use command-line options of Ethereal as well as using Tethereal to capture live packets from the wire or to read saved capture files. This section also details how to import and export files between Ethereal and WinDump, Snort, Snoop, Microsoft Network Monitor, and EtherPeek. The book then teaches the reader to master advanced tasks such as creating sub-trees, displaying bitfields in a graphical view, tracking requests and reply packet pairs as well as exclusive coverage of MATE, Ethereal's brand new configurable upper level analysis engine. The final section to the book teaches readers to enable Ethereal to read new Data sources, program their own protocol dissectors, and to create and customize Ethereal reports. - Ethereal is the #2 most popular open source security tool, according to a recent study conducted by insecure.org - Syngress' first Ethereal book has consistently been one of the best selling security books for the past 2 years

Book Description

Wireshark is the world's most popular network analyzer solution. Used for network troubleshooting, forensics, optimization and more, Wireshark is considered one of the most successful open source projects of all time. Laura Chappell has been involved in the Wireshark project since its infancy (when it was called Ethereal) and is considered the foremost authority on network protocol analysis and forensics using Wireshark. This book consists of 16 labs and is based on the format Laura introduced to trade show audiences over ten years ago through her highly acclaimed "Packet Challenges." This book gives you a chance to test your knowledge of Wireshark and TCP/IP communications analysis by posing a series of questions related to a trace file and then providing Laura's highly detailed step-by-step instructions showing how Laura arrived at the answers to the labs. Book trace files and blank Answer Sheets can be downloaded from this book's supplement page (see https: //www.chappell-university.com/books). Lab 1: Wireshark Warm-Up Objective: Get Comfortable with the Lab Process. Completion of this lab requires many of the skills you will use throughout this lab book. If you are a bit shaky on any answer, take time when reviewing the answers to this lab to ensure you have mastered the necessary skill(s). Lab 2: Proxy Problem Objective: Examine issues that relate to a web proxy connection problem. Lab 3: HTTP vs. HTTPS Objective: Analyze and compare HTTP and HTTPS communications and errors using inclusion and field existence filters. Lab 4: TCP SYN Analysis Objective: Filter on and analyze TCP SYN and SYN/ACK packets to determine the capabilities of TCP peers and their connections. Lab 5: TCP SEQ/ACK Analysis Objective: Examine and analyze TCP sequence and acknowledgment numbering and Wireshark's interpretation of non-sequential numbering patterns. Lab 6: You're Out of Order! Objective: Examine Wireshark's process of distinguishing between out-of-order packets and retransmissions and identify mis-identifications. Lab 7: Sky High Objective: Examine and analyze traffic captured as a host was redirected to a malicious site. Lab 8: DNS Warm-Up Objective: Examine and analyze DNS name resolution traffic that contains canonical name and multiple IP address responses. Lab 9: Hacker Watch Objective: Analyze TCP connections and FTP command and data channels between hosts. Lab 10: Timing is Everything Objective: Analyze and compare path latency, name resolution, and server response times. Lab 11: The News Objective: Analyze capture location, path latency, response times, and keepalive intervals between an HTTP client and server. Lab 12: Selective ACKs Objective: Analyze the process of establishing Selective acknowledgment (SACK) and using SACK during packet loss recovery. Lab 13: Just DNS Objective: Analyze, compare, and contrast various DNS queries and responses to identify errors, cache times, and CNAME (alias) information. Lab 14: Movie Time Objective: Use various display filter types, including regular expressions (regex), to analyze HTTP redirections, end-of-field values, object download times, errors, response times and more. Lab 15: Crafty Objective: Practice your display filter skills using "contains" operators, ASCII filters, and inclusion/exclusion filters, while analyzing TCP and HTTP performance parameters. Lab 16: Pattern Recognition Objective: Focus on TCP conversations and endpoints while analyzing TCP sequence numbers, Window Scaling, keep-alive, and Selective Acknowledgment capabilities.

Mature and powerful, Wireshark is commonly used to find root cause of challenging network issues. This book extends that power to information security professionals, complete with a downloadable, virtual lab environment. Wireshark for Security Professionals covers both offensive and defensive concepts that can be applied to essentially any InfoSec role. Whether into network security, malware analysis, intrusion detection, or penetration testing, this book demonstrates Wireshark through relevant and useful examples. Master Wireshark through both lab scenarios and exercises. Early in the book, a virtual lab environment is provided for the purpose of getting hands-on experience with Wireshark. Wireshark is combined with two popular platforms: Kali, the security-focused Linux distribution, and the Metasploit Framework, the open-source framework for security testing. Lab-based virtual systems generate network traffic for analysis, investigation and demonstration. In addition to following along with the labs you will be challenged with end-of-chapter exercises to expand on covered material. Lastly, this book explores Wireshark with Lua, the light-weight programming language. Lua allows you to extend and customize Wireshark’s features for your needs as a security professional. Lua source code is available both in the book and online. Lua code and lab source code are available online through GitHub, which the book also introduces. The book’s final two chapters greatly draw on Lua and TShark, the command-line interface of Wireshark. By the end of the book you will gain the following: Master the basics of Wireshark Explore the virtual w4sp-lab environment that mimics a real-world network Gain experience using the Debian-based Kali OS among other systems Understand the technical details behind network attacks Execute exploitation and grasp offensive and defensive activities, exploring them through Wireshark Employ Lua to extend Wireshark features and create useful scripts To sum up, the book content, labs and online material, coupled with many referenced sources of PCAP traces, together present a dynamic and robust manual for information security professionals seeking to leverage Wireshark.
