Recommendation:
Recommend the ANG states include this resolution in their aircraft maintenance programs -Technology verifies that there have been no unapproved changes to the LRU’s Operational Flight Program (OFP) or any of the Supply Chain components (software or hardware). - Attestation is also valuable for verifying system integrity after field upgrades or after the completion of cyber testing. - For fielded systems that have been deployed for a length of time, Attestation can provide early detection of component degradation prior to failure. - This allows for proactive maintenance in the avionics to ensure successful and timely missions execution. - Attestation verification is accomplished using an external “trusted verifier” to examine the LRU’s memory contents and devices using direct access to an existing port of an LRU and then using a chained access technique in which the trusted verifier communicates through a verified LRU to a down stream LRU. - Specific System Utility: - Provides cyber security to existing legacy systems (no modifications to hardware or aircraft wiring) - Provides verification of system integrity after field upgrade or cyber testing - Can provide an early indicator of component degradation prior to failure
