Matrix analysis of the insider threat (MAIT) user's manual

MAIT is a sophisticated method for the analysis of safeguards or security systems that determines if single or multiple insiders can covertly sabotage a facility or system, or can covertly divert a resource that is present in the facility or system. The MAIT method provides a detailed, organized way to exhaustively examine the safeguards or security system against these covert threats. An evaluation of this broad scope is beyond the reasonable capability of an analyst working without computer assistance. The MAIT analysis is conducted by first manually collecting detailed facility design data and access and control information for each individual safeguard measure. With this information, the MAIT computer code synthesizes every possible situation and returns data to the analyst concerning those particular events that are not adequately protected. This report replaces the previous user's manual (SAI-78-960-LJ). It includes the details that an analyst needs to know to use the upgraded MAIT evaluation method. The major changes incorporated in the present version of the method include the evaluation of scenarios that span two conditions, the consolidation of theft and sabotage versions of the program and the incorporation and consideration of secondary targets in a path
