NetHide - Secure and Practical Network Topology Obfuscation
Explore a 24-minute conference talk from USENIX Security '18 that introduces NetHide, a novel framework for secure network topology obfuscation. Dive into the challenges of balancing network security against link-flooding attacks with the practical needs of network debugging tools. Learn how NetHide formulates topology obfuscation as a multi-objective optimization problem, allowing for flexible trade-offs between security and usability. Discover how this approach can protect large network topologies while preserving essential debugging capabilities. Examine the implementation of NetHide using programmable network devices to modify path tracing probes in real-time. Gain insights into the effectiveness of this method in obfuscating topologies of up to 150 nodes while maintaining the ability to trace back 90% of link failures accurately.
