Who This Book Is For

Are you curious to know what''s going on in a network? Do you get frustrated when you are unable to detect the cause of problems in your networks? This is where the book comes into play.

Mastering Wireshark is for developers or network enthusiasts who are interested in understanding the internal workings of networks and have prior knowledge of using Wireshark, but are not aware about all of its functionalities.

What You Will Learn

Install Wireshark and understand its GUI and all the functionalities of itCreate and use different filtersAnalyze different layers of network protocols and know the amount of packets that flow through the networkDecrypt encrypted wireless trafficUse Wireshark as a diagnostic tool and also for network security analysis to keep track of malwareTroubleshoot all the network anomalies with help of Wireshark Resolve latencies and bottleneck issues in the network

In Detail

Wireshark is a popular and powerful tool used to analyze the amount of bits and bytes that are flowing through a network. Wireshark deals with the second to seventh layer of network protocols, and the analysis made is presented in a human readable form.

Mastering Wireshark will help you raise your knowledge to an expert level. At the start of the book, you will be taught how to install Wireshark, and will be introduced to its interface so you understand all its functionalities. Moving forward, you will discover different ways to create and use capture and display filters. Halfway through the book, you''ll be mastering the features of Wireshark, analyzing different layers of the network protocol, looking for any anomalies. As you reach to the end of the book, you will be taught how to use Wireshark for network security analysis and configure it for troubleshooting purposes.

Style and approach

Every chapter in this book is explained to you in an easy way accompanied by real-life examples and screenshots of the interface, making it easy for you to become an expert at using Wireshark.

Master Wireshark and discover how to analyze network packets and protocols effectively, along with engaging recipes to troubleshoot network problemsAbout 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 snifferWho This Book Is ForThis 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 networkIn DetailThis 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 Essentials2) Network Analysis Using Wireshark Cookbook3) Mastering WiresharkStyle and approachThis 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.
