Explore 802.1x network access control and bypass techniques in this 31-minute talk from Hack in Paris. Dive into the importance of network access control in today's cybersecurity landscape, where social engineering and physical attacks often lead to advanced persistent threats. Examine why the 802.1x protocol should not be considered a foolproof solution for protecting critical assets and systems. Learn about potential vulnerabilities and stealthy bypass methods that attackers might exploit. Begin with a brief overview of the 802.1x protocol and its authentication scheme before focusing on various techniques an attacker could use to gain unauthorized access to a 802.1x-protected LAN. Witness a practical demonstration of these bypass techniques, including the use of Fenrir, to better understand the potential risks and improve your network security strategies.
