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.

Get to grips with network-based attacks and learn to defend your organization\'s network and network devicesKey FeaturesBook DescriptionWith the increased demand for computer systems and the ever-evolving internet, network security now plays an even bigger role in securing IT infrastructures against attacks. Equipped with the knowledge of how to find vulnerabilities and infiltrate organizations through their networks, you’ll be able to think like a hacker and safeguard your organization’s network and networking devices. Network Protocols for Security Professionals will show you how.This comprehensive guide gradually increases in complexity, taking you from the basics to advanced concepts. Starting with the structure of data network protocols, devices, and breaches, you’ll become familiar with attacking tools and scripts that take advantage of these breaches. Once you’ve covered the basics, you’ll learn about attacks that target networks and network devices. Your learning journey will get more exciting as you perform eavesdropping, learn data analysis, and use behavior analysis for network forensics. As you progress, you’ll develop a thorough understanding of network protocols and how to use methods and tools you learned in the previous parts to attack and protect these protocols.By the end of this network security book, you’ll be well versed in network protocol security and security countermeasures to protect network protocols.What you will learnUnderstand security breaches, weaknesses, and protection techniquesAttack and defend wired as well as wireless networksDiscover how to attack and defend LAN-, IP-, and TCP/UDP-based vulnerabilitiesFocus on encryption, authorization, and authentication principlesGain insights into implementing security protocols the right wayUse tools and scripts to perform attacks on network devicesWield Python, PyShark, and other scripting tools for packet analysisIdentify attacks on web servers to secure web and email servicesWho this book is forThis book is for red team and blue team pentesters, security professionals, or bug hunters. Anyone involved in network protocol management and security will also benefit from this book. Basic experience in network security will be an added advantage.

This book will be a massive ally in troubleshooting your network using Wireshark, the world\'s most popular analyzer. Over 100 practical recipes provide a focus on real-life situations, helping you resolve your own individual issues.Key FeaturesPlace Wireshark in the network and configure it for effective network analysisUse Wireshark's powerful statistical tools and expert system for pinpointing network problemsUse Wireshark for troubleshooting network performance, applications, and security problems in the networkBook DescriptionIs your network slow? Are your users complaining? Disconnections? IP Telephony problems? Video freezes? Network analysis is the process of isolating these problems and fixing them, and Wireshark has long been the most popular network analyzer for achieving this goal. Based on hundreds of solved cases, Network Analysis using Wireshark Cookbook provides you with practical recipes for effective Wireshark network analysis to analyze and troubleshoot your network."Network analysis using Wireshark Cookbook" highlights the operations of Wireshark as a network analyzer tool. This book provides you with a set of practical recipes to help you solve any problems in your network using a step-by-step approach."Network analysis using Wireshark Cookbook" starts by discussing the capabilities of Wireshark, such as the statistical tools and the expert system, capture and display filters, and how to use them. The book then guides you through the details of the main networking protocols, that is, Ethernet, LAN switching, and TCP/IP, and then discusses the details of application protocols and their behavior over the network. Among the application protocols that are discussed in the book are standard Internet protocols like HTTP, mail protocols, FTP, and DNS, along with the behavior of databases, terminal server clients, Citrix, and other applications that are common in the IT environment.In a bottom-up troubleshooting approach, the book goes up through the layers of the OSI reference model explaining how to resolve networking problems. The book starts from Ethernet and LAN switching, through IP, and then 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. The book finishes with a look at network forensics and how to search and find security problems that might harm the network.What you will learnConfigure Wireshark for effective network troubleshootingSet up various display and capture filtersUse basic statistical tools that provide you with "who is talking" tables, conversations, and HTTP statisticsMaster both the standard and advanced features of IO graphsUse the expert system to pinpoint various types of events that might influence the behavior of your networkLearn about Wi-Fi testing and how to resolve problems related to wireless LANsExplore performance issues in TCP/IPExplore failures due to delays and jitters in the networkFind and resolve problems due to bandwidth, throughput, and packet lossIdentify and locate faults in communication applications including HTTP, FTP, mail, and various other applications – Microsoft OS problems, databases, voice, and video over IPIdentify and locate faults in detecting security failures and security breaches in the networkWho this book is forThis book is aimed at research and development professionals, engineering and technical support, and IT and communications managers who are using Wireshark for network analysis and troubleshooting. This book requires a basic understanding of networking concepts, but does not require specific and detailed technical knowledge of protocols or vendor implementations.
