ARP Vulnerabilities - Indefensible Local Network Attacks

Black Hat via YouTube

Overview

Explore the vulnerabilities of Address Resolution Protocol (ARP) and their potential for indefensible local network attacks in this Black Hat USA 2001 conference talk. Delve into ARP message formats, including request and reply messages, and examine various attack types such as sniffing on hubs and switches, host-to-host exploits, and router exploits. Learn about session hijacking, man-in-the-middle attacks, and denial of service techniques. Investigate countermeasures like session encryption, strong authentication, and port security. Discuss operating system vulnerabilities, firewall considerations, and IDS architecture issues. Gain insights into OS-level detection methods and hypothetical detection applications. Review public domain tools and a comprehensive bibliography before concluding with a demonstration of the discussed concepts in a practical environment.
