Use Wireshark 2 to overcome real-world network problems Key Features * Delve into the core functionalities of the latest version of Wireshark * Master network security skills with Wireshark 2 * ...Efficiently find the root cause of network-related issues Book Description Wireshark, a combination of a Linux distro (Kali) and an open source security framework (Metasploit), is a popular and powerful tool. Wireshark is mainly used to analyze the bits and bytes that flow through a network. It efficiently deals with the second to the seventh layer of network protocols, and the analysis made is presented in a form that can be easily read by people. Mastering Wireshark 2 helps you gain expertise in securing your network. We start with installing and setting up Wireshark2.0, and then explore its interface in order to understand all of its functionalities. As you progress through the chapters, you will discover different ways to create, use, capture, and display filters. By halfway through the book, you will have mastered Wireshark features, analyzed different layers of the network protocol, and searched for anomalies. You'll learn about plugins and APIs in depth. Finally, the book focuses on pocket analysis for security tasks, command-line utilities, and tools that manage trace files. By the end of the book, you'll have learned how to use Wireshark for network security analysis and configured it for troubleshooting purposes. What you will learn * Understand what network and protocol analysis is and how it can help you * Use Wireshark to capture packets in your network * Filter captured traffic to only show what you need * Explore useful statistic displays to make it easier to diagnose issues * Customize Wireshark to your own specifications * Analyze common network and network application protocols Who this book is for If you are a security professional or a network enthusiast and are interested in understanding the internal working of networks, and if you have some prior knowledge of using Wireshark, then this book is for you.
Today's urban environments are layered with data and algorithms that fundamentally shape how we perceive and move through space. But are our digitally dense environments continuing to amplify ...inequalities rather than alleviate them? This book looks at the key contours of information inequality, and who, what and where gets left out. Platforms like Google Maps and Wikipedia have become important gateways to understanding the world, and yet they are characterised by significant gaps and biases, often driven by processes of exclusion. As a result, their digital augmentations tend to be refractions rather than reflections: they highlight only some facets of the world at the expense of others. This doesn't mean that more equitable futures aren't possible. By outlining the mechanisms through which our digital and material worlds intersect, the authors conclude with a roadmap for what alternative digital geographies might look like.
Providing readers with a unique guide of how businesses can achieve resilience to digital conflict, Conflict Management in Digital Businesshelps prepare for unexpected situations such as pandemics, ...to maintain competitive advantage, and illuminating pathways to turn conflicts caused by extraordinary situations into opportunities.
Today almost every aspect of life for which data exists can be rendered as a network. Financial data, social networks, biological ecologies: all are visualized in links and nodes, lines connecting ...dots. A network visualization of a corporate infrastructure could look remarkably similar to that of a terrorist organization. In An Aesthesia of Networks , Anna Munster argues that this uniformity has flattened our experience of networks as active and relational processes and assemblages. She counters the "network anaesthesia" that results from this pervasive mimesis by reinserting the question of experience, or aesthesia, into networked culture and aesthetics. Rather than asking how humans experience computers and networks, Munster asks how networks experience -- what operations they perform and undergo to change and produce new forms of experience. Drawing on William James's radical empiricism, she asserts that networked experience is assembled first and foremost through relations, which make up its most immediately sensed and perceived aspect. Munster critically considers a range of contemporary artistic and cultural practices that engage with network technologies and techniques, including databases and data mining, the domination of search in online activity, and the proliferation of viral media through YouTube. These practices -- from artists who "undermine" data to musicians and VJs who use intranetworked audio and video software environments -- are concerned with the relationality at the core of today's network experience.
Digital identity can be defined as the digital representation of the information known about a specific individual or organization. Digital identity management technology is an essential function in ...customizing and enhancing the network user experience, protecting privacy, underpinning accountability in transactions and interactions, and complying with regulatory controls. This practical resource offers you a in-depth understanding of how to design, deploy and assess identity management solutions. It provides a comprehensive overview of current trends and future directions in identity management, including best practices, the standardization landscape, and the latest research finding. Additionally, you get a clear explanation of fundamental notions and techniques that cover the entire identity lifecycle.
Prepare yourself for the next generation networking skills and acquire the knowledge needed to secure the routers. Key Features * Build foundational Cisco networking skills and prepare yourself for ...next-generation network transformation * Take practice questions and mock tests to check how prepared you are for the CCNA exam * Gain a strong understanding of network communication with the help of practical examples Book Description Cisco Certified Network Associate (CCNA) Routing and Switching is one of the most important qualifications for keeping your networking skills up to date. CCNA Routing and Switching 200-125 Certification Guide covers topics included in the latest CCNA exam, along with review and practice questions. This guide introduces you to the structure of IPv4 and IPv6 addresses and examines in detail the creation of IP networks and sub-networks and how to assign addresses in the network. You will then move on to understanding how to configure, verify, and troubleshoot layer 2 and layer 3 protocols. In addition to this, you will discover the functionality, configuration, and troubleshooting of DHCPv4. Combined with router and router simulation practice, this certification guide will help you cover everything you need to know in order to pass the CCNA Routing and Switching 200-125 exam. By the end of this book, you will explore security best practices, as well as get familiar with the protocols that a network administrator can use to monitor the network. What you will learn * Gain an in-depth understanding of networking using routers and switches * Understand layer 2 technology and its various configurations and connections * Configure default, static, and dynamic routing * Design and implement subnetted IPv4 and IPv6 addressing schemes * Troubleshoot issues and keep your network secure * Study the importance of VLANs for security and optimizing the bandwidth Who this book is for This book is for you if you are a network administrator, network technician, or anyone who wants to prepare for CCNA Routing and Switching certification.

Introduction to Network Simulator NS2 is a primer providing materials for NS2 beginners, whether students, professors, or researchers for understanding the architecture of Network Simulator 2 (NS2) ...and for incorporating simulation modules into NS2. The authors discuss the simulation architecture and the key components of NS2 including simulation-related objects, network objects, packet-related objects, and helper objects. The NS2 modules included within are nodes, links, SimpleLink objects, packets, agents, and applications. Further, the book covers three helper modules: timers, random number generators, and error models. Also included are chapters on summary of debugging, variable and packet tracing, result compilation, and examples for extending NS2. Two appendices provide the details of scripting language Tcl, OTcl and AWK, as well object oriented programming used extensively in NS2.
