Abstract: Systems and methods of evaluation of threats to elements of a client computer application having a cyber reference library, an opponent catalog and a network model. The systems and methods produce a set of analyst reports evaluating the threats to the client computer application. One embodiment of the system for evaluating at least one threat to a client computer application has a threat evaluation engine which performs a plurality of algorithms, where each algorithm of has implementation specific needs for input into the individual algorithm, a threat evaluation results data store, a statistical analysis engine, and an analysis results data store.
