Wireshark Revealed: Essential Skills for IT Professionals

Master Wireshark and discover how to analyze network packets and protocols effectively, along with engaging recipes to troubleshoot network problems About This Book * Gain valuable insights into the network and application protocols, and the key fields in each protocol * Use Wireshark's powerful statistical tools to analyze your network and leverage its expert system to pinpoint network problems * Master Wireshark and train it as your network sniffer Who This Book Is For This book is aimed at IT professionals who want to develop or enhance their packet analysis skills. A basic familiarity with common network and application services terms and technologies is assumed. What You Will Learn * Discover how packet analysts view networks and the role of protocols at the packet level * Capture and isolate all the right packets to perform a thorough analysis using Wireshark's extensive capture and display filtering capabilities * Decrypt encrypted wireless traffic * Use Wireshark as a diagnostic tool and also for network security analysis to keep track of malware * Find and resolve problems due to bandwidth, throughput, and packet loss * Identify and locate faults in communication applications including HTTP, FTP, mail, and various other applications - Microsoft OS problems, databases, voice, and video over IP * Identify and locate faults in detecting security failures and security breaches in the network In Detail This Learning Path starts off installing Wireshark, before gradually taking you through your first packet capture, identifying and filtering out just the packets of interest, and saving them to a new file for later analysis. You will then discover different ways to create and use capture and display filters. By halfway through the book, you'll be mastering Wireshark features, analyzing different layers of the network protocol, and looking for any anomalies.We then start Ethernet and LAN switching, through IP, and then move on to TCP/UDP with a focus on TCP performance problems. It also focuses on WLAN security. Then, we go through application behavior issues including HTTP, mail, DNS, and other common protocols. This book finishes with a look at network forensics and how to locate security problems that might harm the network.This course provides you with highly practical content explaining Metasploit from the following books: 1) Wireshark Essentials 2) Network Analysis Using Wireshark Cookbook 3) Mastering Wireshark Style and approach This step-by-step guide follows a practical approach, starting from the basic to the advanced aspects. Through a series of real-world examples, this learning path will focus on making it easy for you to become an expert at using Wireshark.

精通Wireshark，並學習如何有效地分析網絡封包和協議，以及解決網絡問題的方法。

關於本書
- 獲得有關網絡和應用協議以及每個協議中的關鍵字段的寶貴見解。
- 使用Wireshark強大的統計工具來分析您的網絡，並利用其專家系統來定位網絡問題。
- 精通Wireshark，並將其訓練為您的網絡封包嗅探器。

本書適合對開發或增強封包分析技能有興趣的IT專業人士。假設讀者對常見的網絡和應用服務術語和技術有基本的了解。

您將學到什麼
- 了解封包分析師如何查看網絡以及協議在封包級別的作用。
- 使用Wireshark的廣泛捕獲和顯示過濾功能，捕獲和隔離所有正確的封包進行全面分析。
- 解密加密的無線流量。
- 使用Wireshark作為診斷工具，並用於網絡安全分析以追踪惡意軟件。
- 找到並解決由帶寬、吞吐量和封包丟失引起的問題。
- 識別和定位通信應用程序中的故障，包括HTTP、FTP、郵件和其他各種應用程序- Microsoft操作系統問題、數據庫、語音和視頻IP。
- 識別和定位檢測安全故障和網絡安全漏洞。

詳細內容
本學習路徑從安裝Wireshark開始，逐步引導您進行第一次封包捕獲，識別並過濾出感興趣的封包，並將它們保存到新文件以供後續分析。然後，您將發現創建和使用捕獲和顯示過濾器的不同方法。到了書的一半，您將精通Wireshark的功能，分析網絡協議的不同層次，並尋找任何異常。然後，我們將介紹以太網和局域網交換，然後轉向IP，然後轉向TCP/UDP，重點關注TCP性能問題。它還專注於WLAN安全。然後，我們將介紹應用程序行為問題，包括HTTP、郵件、DNS和其他常見協議。本書以網絡取證和如何定位可能損害網絡的安全問題結束。
