Book Description
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.

Book Description
Hands-on networking experience, without the lab! The best way to learn about network protocols is to see them in action. But that doesn't mean that you need a lab full of networking equipment. This revolutionary text and its accompanying CD give readers realistic hands-on experience working with network protocols, without requiring all the routers, switches, hubs, and PCs of an actual network. Computer Networking: Internet Protocols in Action provides packet traces of real network activity on CD. Readers open the trace files using Ethereal, an open source network protocol analyzer, and follow the text to perform the exercises, gaining a thorough understanding of the material by seeing it in action. Features * Practicality: Readers are able to learn by doing, without having to use actual networks. Instructors can add an active learning component to their course without the overhead of collecting the materials. * Flexibility: This approach has been used successfully with students at the graduate and undergraduate levels. Appropriate for courses regardless of whether the instructor uses a bottom-up or a top-down approach. * Completeness: The exercises take the reader from the basics of examining quiet and busy networks through application, transport, network, and link layers to the crucial issues of network security.

Seven Deadliest Network Attacks

Pages : 157

Book Description
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

Book Description
The attacks on computers and business networks are growing daily, and the need for security professionals who understand how malfeasants perform attacks and compromise networks is a growing requirement to counter the threat. Network security education generally lacks appropriate textbooks with detailed, hands-on exercises that include both offensive and defensive techniques. Using step-by-step processes to build and generate attacks using offensive techniques, Network Attacks and Defenses: A Hands-on Approach enables students to implement appropriate network security solutions within a laboratory environment. Topics covered in the labs include: Content Addressable Memory (CAM) table poisoning attacks on network switches Address Resolution Protocol (ARP) cache poisoning attacks The detection and prevention of abnormal ARP traffic Network traffic sniffing and the detection of Network Interface Cards (NICs) running in promiscuous mode Internet Protocol-Based Denial-of-Service (IP-based DoS) attacks Reconnaissance traffic Network traffic filtering and inspection Common mechanisms used for router security and device hardening Internet Protocol Security Virtual Private Network (IPsec VPN) security solution protocols, standards, types, and deployments Remote Access IPsec VPN security solution architecture and its design, components, architecture, and implementations These practical exercises go beyond theory to allow students to better anatomize and elaborate offensive and defensive techniques. Educators can use the model scenarios described in this book to design and implement innovative hands-on security exercises. Students who master the techniques in this book will be well armed to counter a broad range of network security threats.
