Abstract
The Analytic System and Software for Evaluation of Safeguards and Security (ASSESS) gathers site information in its Facility module, storing an Adversary Sequence Diagram (ASD) and data about two conditions for each ASD path element, and then uses this data in Insider and Outsider evaluation modules. There has been a modeling conflict in describing such cases as a vault that is open occasionally during the day: modeled for the Insider module, the two conditions record protection when the vault is \"Open\" and \"Closed\" but the Outsider module will then treat the vault as open during the day. Capabilities have been added to Outsider to let the user mix facility data across conditions instead of the present assumption that the adversary intrusion occurs with all ASD elements either in the first or second condition. In the example above, the Outsider analyst can now set the vault closed instead of open. Analysts may also remove elements from the ASD in Outsider during analysis, allowing them to create extra elements, either to model further states or to represent different upgrades. Elements can also be removed to achieve a better match between the interruption path and neutralization conditions.
