Download or read book Attacking Network Protocols written by James Forshaw and published by No Starch Press. This book was released on 2018-01-02 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: Attacking Network Protocols is a deep dive into network protocol security from James ­Forshaw, one of the world’s leading bug ­hunters. This comprehensive guide looks at networking from an attacker’s perspective to help you discover, exploit, and ultimately ­protect vulnerabilities. You’ll start with a rundown of networking basics and protocol traffic capture before moving on to static and dynamic protocol analysis, common protocol structures, cryptography, and protocol security. Then you’ll turn your focus to finding and exploiting vulnerabilities, with an overview of common bug classes, fuzzing, debugging, and exhaustion attacks. Learn how to: - Capture, manipulate, and replay packets - Develop tools to dissect traffic and reverse engineer code to understand the inner workings of a network protocol - Discover and exploit vulnerabilities such as memory corruptions, authentication bypasses, and denials of service - Use capture and analysis tools like ­Wireshark and develop your own custom network proxies to manipulate ­network traffic Attacking Network Protocols is a must-have for any penetration tester, bug hunter, or developer looking to understand and discover network vulnerabilities.

Available in PDF, EPUB and Kindle. Book excerpt: Take an in-depth tour of core Internet protocols and learn how they work together to move data packets from one network to another. With this updated edition, you’ll dive into the aspects of each protocol, including operation basics and security risks, and learn the function of network hardware such as switches and routers. New chapters examine the transmission control protocol (TCP) and user datagram protocol in detail. Ideal for beginning network engineers, each chapter in this book includes a set of review questions, as well as practical, hands-on lab exercises. You’ll explore topics including: Basic network architecture: how protocols and functions fit together The structure and operation of the Ethernet protocol TCP/IP protocol fields, operations, and addressing used for networks The address resolution process in a typical IPv4 network Switches, access points, routers, and components that process packets TCP details, including packet content and client-server packet flow How the Internet Control Message Protocol provides error messages during network operations How network mask (subnetting) helps determine the network The operation, structure, and common uses of the user datagram protocol

Download or read book Hacking VoIP written by Himanshu Dwivedi and published by No Starch Press. This book was released on 2009 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: Voice over Internet Protocol (VoIP) networks, the technology used to place phone calls through the Internet, suffer from the same security holes as standard IP networks. This book reviews the many possible VoIP attacks, and discusses the best defenses against them.

Download or read book Computer Networking written by Jeanna Matthews and published by John Wiley & Sons. This book was released on 2005-01-03 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: This revolutionary text and its accompanying CD replace a whole lab full of computer equipment. They give computer science students realistic hands-on experience working with network protocols, without requiring all the routers, switches, hubs, and PCs of an actual network. Using the latest version of the open source program Ethereal, the reader opens packet trace files from the CD and follows the text to perform the exercises, gaining a thorough understanding of the material in the best way possible—by seeing it in action. This approach also benefits the instructor, who is spared the time-consuming tasks of maintaining a laboratory and taking traces. It can even relieve the anxiety system administrators have about students collecting traces on campus networks!

Download or read book Introduction to Network Security written by Douglas Jacobson and published by CRC Press. This book was released on 2008-11-18 with total page 502 pages. Available in PDF, EPUB and Kindle. Book excerpt: Unlike data communications of the past, today's networks consist of numerous devices that handle the data as it passes from the sender to the receiver. However, security concerns are frequently raised in circumstances where interconnected computers use a network not controlled by any one entity or organization. Introduction to Network Security exam

Download or read book Seven Deadliest Network Attacks written by Stacy Prowell and published by Elsevier. This book was released on 2010-06-02 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seven Deadliest Network Attacks identifies seven classes of network attacks and discusses how the attack works, including tools to accomplish the attack, the risks of the attack, and how to defend against the attack. This book pinpoints the most dangerous hacks and exploits specific to networks, laying out the anatomy of these attacks including how to make your system more secure. You will discover the best ways to defend against these vicious hacks with step-by-step instruction and learn techniques to make your computer and network impenetrable. The book consists of seven chapters that deal with the following attacks: denial of service; war dialing; penetration testing; protocol tunneling; spanning tree attacks; man-in-the-middle; and password replay. These attacks are not mutually exclusive and were chosen because they help illustrate different aspects of network security. The principles on which they rely are unlikely to vanish any time soon, and they allow for the possibility of gaining something of interest to the attacker, from money to high-value data. This book is intended to provide practical, usable information. However, the world of network security is evolving very rapidly, and the attack that works today may (hopefully) not work tomorrow. It is more important, then, to understand the principles on which the attacks and exploits are based in order to properly plan either a network attack or a network defense. Seven Deadliest Network Attacks will appeal to information security professionals of all levels, network admins, and recreational hackers. - Knowledge is power, find out about the most dominant attacks currently waging war on computers and networks globally - Discover the best ways to defend against these vicious attacks; step-by-step instruction shows you how - Institute countermeasures, don't be caught defenseless again, and learn techniques to make your computer and network impenetrable

Download or read book Practical IoT Hacking written by Fotios Chantzis and published by No Starch Press. This book was released on 2021-03-23 with total page 466 pages. Available in PDF, EPUB and Kindle. Book excerpt: The definitive guide to hacking the world of the Internet of Things (IoT) -- Internet connected devices such as medical devices, home assistants, smart home appliances and more. Drawing from the real-life exploits of five highly regarded IoT security researchers, Practical IoT Hacking teaches you how to test IoT systems, devices, and protocols to mitigate risk. The book begins by walking you through common threats and a threat modeling framework. You’ll develop a security testing methodology, discover the art of passive reconnaissance, and assess security on all layers of an IoT system. Next, you’ll perform VLAN hopping, crack MQTT authentication, abuse UPnP, develop an mDNS poisoner, and craft WS-Discovery attacks. You’ll tackle both hardware hacking and radio hacking, with in-depth coverage of attacks against embedded IoT devices and RFID systems. You’ll also learn how to: • Write a DICOM service scanner as an NSE module • Hack a microcontroller through the UART and SWD interfaces • Reverse engineer firmware and analyze mobile companion apps • Develop an NFC fuzzer using Proxmark3 • Hack a smart home by jamming wireless alarms, playing back IP camera feeds, and controlling a smart treadmill The tools and devices you’ll use are affordable and readily available, so you can easily practice what you learn. Whether you’re a security researcher, IT team member, or hacking hobbyist, you’ll find Practical IoT Hacking indispensable in your efforts to hack all the things REQUIREMENTS: Basic knowledge of Linux command line, TCP/IP, and programming
