AWDRAT: A Cognitive Middleware System for Information Survivability
The Infrastructure of modern society is controlled by software systems that are vulnerable to attacks. Many such attacks, launched by "recreational hackers" have already led to severe disruptions and significant cost. It, therefore, is critical that we find ways to protect such systems and to enable them to continue functioning even after a successful attack. This paper describes AWDRAT, a middleware system for providing survivability to both new and legacy applications. AWDRAT stands for Architectural-differencing, Wrappers, Diagnosis, Recovery, Adaptive software, and Trust-modeling. AWDRAT uses these techniques to gain visibility into the execution of an application system and to compare the application's actual behavior to that which is expected. In the case of a deviation, AWDRAT conducts a diagnosis that figures out which computational resources are likely to have been compromised and then adds these assessments to its trust-model. The trust model in turn guides th...
