Until now network security defences have largely been about building walls and fences around the network. This talk revolves around spiking those walls & electrifying those fences! During this talk we will highlight techniques (and tools) that can be used to turn the tables on prospective attackers with passive-Strike-Back. We will explore the possibilities across the assesment spectrum responding to the standard assesment phases of Intelligence gathering, Reconnaissance & Attack with Disinformation, Misdirection, Camouflage, Obfuscation & Proportional Response.
