With this presentation we will demonstrate a new tool called eescan that automates extrusion and exploitability scanning using a client/server approach. Eescan will be released under the GPL and utilizes python to create an extensible framework for testing extrusion and exploit defenses.
All network security systems have gaps. Layered security tries to cover the gaps with overlapping protections like firewalls, intrusion prevention, proxies and other mechanisms. How do you really know where the gaps are before the weeds grow through? Vulnerability assessment tools scan for vulnerable systems from an attackers perspective. This technique has value but fails to represent the risk posed by client application usage and attacks. They also fail to assess extrusions - the traffic content allowed to leave a network.
Extrusion and exploitability scanning attempts to find these gaps using an automated scanning framework. The scanning techniques simulate user and attacker behavior from the client perspective to holistically measure the amount of risk in a given security system.
