Intrusion tolerant system for integrated vetronics survivability strategy

Intrusions on the vetronics architecture often target specific applications. Intruders exploit vulnerabilities in the architecture and try to halt services or make them behave abnormally. The traditional security approach relies on the fortress model. That is, like a fortress, a preventive wall is built to ensure that the system is not penetrated. Survivability addresses the issue of security on the vetronics architecture. This paper make recommendations for improvements on the recognition and recovery mechanism of the vetronics survivability strategies by introducing a mechanism for intrusion tolerance to the architecture. This mechanism focuses on addressing the symptoms caused by an attack rather than preventing or detecting, diagnosing, contain or eradicating an attack. Strategies for adaptive responses that are unpredictable to an attacker are described. Finally, requirements for bridging the gap between the services and the infrastructure is presented.
