Take a systematic approach at identifying intrusions that range from the most basic to the most sophisticated, using Wireshark, an open source protocol analyzer. This book will show you how to effectively manipulate and monitor different conversations and perform statistical analysis of these conversations to identify the IP and TCP information of interest. Next, you'll be walked through a review of the different methods malware uses, from inception through the spread across and compromise of a network of machines. The process from the initial “click” through intrusion, the characteristics of Command and Control (C2), and the different types of lateral movement will be detailed at the packet level. In the final part of the book, you'll explore the network capture file and identification of data for a potential forensics extraction, including inherent capabilities for the extraction of objects such as file data and other corresponding components in support of a forensics investigation. After completing this book, you will have a complete understanding of the process of carving files from raw PCAP data within the Wireshark tool. What You Will Learn Use Wireshark to identify intrusions into a network Exercise methods to uncover network data even when it is in encrypted form Analyze malware Command and Control (C2) communications and identify IOCs Extract data in a forensically sound manner to support investigations Leverage capture file statistics to reconstruct network events Who This Book Is ForNetwork analysts, Wireshark analysts, and digital forensic analysts.

Description Speed up your workflow and enhance your analysis by becoming better acquainted with the Wireshark interface and its core features. In this course, join Lisa Bock as she helps to familiarize you with this powerful protocol analysis tool. Lisa reviews the menu choices, explains each of the toolbars available, and shares tips for modifying the Wireshark interface to suit your needs. Discover capture options and understand the difference between capture and display filters. Learn how to efficiently find and mark packets, and fine-tune columns, fonts, and colors. Create configuration protocols and easily add comments to a single packet or to the entire capture, all with the goal of helping you navigate easier in Wireshark.

Introduction WireShark is the world’s foremost network protocol analyzer, and an essential tool for any system administrator or cybersecurity professional. This tool is also free and cross-platform. WireShark: The World’s Foremost Network Protocol Analyzer It’s free, open source, cross-platform and widely-used network protocol analyzer that supports various protocols. WireShark can read and process capture files from a number of different products, including other sniffers, routers, and network utilities. It uses Qt (graphical user interface library), a very popular Promiscuous Capture Library (libpcap), a packet capture and filtering library. It also comes with TShark (a line-oriented sniffer), a terminal-based (non-GUI) version. You can use WireShark to troubleshoot network problems, examine security problems, verify network applications, debug protocol implementations, and also to learn network protocol internals. Wireshark uses a library called pcap for capturing the network packets. History: Wireshark has been around since 1998, when it was invented by Gerald Combs and called Ethereal. In May 2006, Combs change the name to Wireshark, since he didn’t own the Ethereal trademark. Over the years it has won several industry awards and received a lot of community support. WireShark is the most known and the most used network analyzer today. Features: Deep inspection of hundreds of protocols Live capture and offline analysis. Standard three-pane packet browser. Multi-platform: Runs on Windows, Linux, macOS, Solaris, FreeBSD, NetBSD, and many others. Captured network data can be browsed via a GUI, or via the TTY-mode TShark utility. The most powerful display filters in the industry. Rich VoIP analysis. Read/write many different capture file formats. Capture files compressed with gzip can be decompressed on the fly. Live data can be read from Ethernet, IEEE 802.11, PPP/HDLC, ATM, Bluetooth, USB, Token Ring, Frame Relay, FDDI, and others (depending on your platform). Decryption support for many protocols, including: IPsec, ISAKMP, Kerberos, SNMPv3, SSL/TLS, WEP, and WPA/WPA2. You can apply coloring rules to the packet list for quick, intuitive analysis. Output can be exported to XML, PostScript®, CSV, or plain text. [hide][Hidden Content]]
