Information security in integrated avionic systems

Integrated avionic systems are being developed for application in the majority of future military aircraft. In these applications, the current technique of integrating and maintaining information security (INFOSEC) by using discrete electronic systems and wiring is no longer adequate. The author defines the areas of concern and provides direction for determining the requirements to maintain INFOSEC within the integrated avionic system. He concludes that INFOSEC in integrated avionic systems requires a coherent set of operational/system security policies and trusted computing base designs supported by communication security (COMSEC) and TEMPEST techniques. This coherence prevents costly overkill and inadequate designs. Full time INFOSEC engineering from each INFOSEC technology must be included in the avionic system design from the beginning
