Security services for airborne networking

Communications and processing for Net-Centric Airborne Networks may become more vulnerable as additional nodes and entities are added to the networks. Accordingly, Information Assurance must provide greater protections in the face of these wider vulnerabilities. The capabilities of legacy systems still provide a basis for IA, but new operating modes mean that new capabilities are needed to mitigate vulnerabilities and blunt attacks that will ensue as the networks are deployed operationally. We discuss the transition from existing IA capabilities to broader methods for each of the IA services of confidentiality, integrity, availability, authentication, and non-repudiation. We also include some discussion of network issues and defenses that are becoming more important as we go forward.
