Integrated vetronics survivability: Requirements for vetronics survivability strategies

Vetronics in modern day military vehicles have evolved to include network enabled capability (NEC) allowing the use of electronics architectures to integrate different sub-systems. Integrated vehicle electronics (vetronics) offer improved performance, efficiency and new capabilities at the sub system, system and system-of-systems level. However, this integration is associated with magnified risk and compromise from cyber attacks. Potential cyber attacks could be from an external source where a node is accessed by a malicious intruder using NEC, or internal to the vehicle such as a passive attack waiting to be triggered by an event. This paper provides an understanding of applying survivable systems principles of preventive and reactive mechanisms to the vehicle´s integrated vetronics in order to mitigate internal and external threats. Requirements are derived and a novel top level architecture for vetronics survivability is presented.
