Autonomic Networking is Cisco's vision for smart networks. Cisco developed one technology where you need to write only 5 commands to build a whole network of hundreds of nodes, no additional configuration, no hassle. All the communication between the nodes is encrypted and the configuration on the nodes is hidden. It is now supported on IOS and IOS XE. Join me, where I will introduce Cisco's Autonomic Networking, analyze its architecture, crack their proprietary protocol then take the Autonomic Networking down. Two new vulnerabilities will be disclosed through the talk, one of them capable of taking down Cisco devices just by knowing their IPv6 address.
