Optimization Analysis Optimization analysis is the reapplica- tion of the vulnerability analysis after implementing hypothetical improve- ments resulting from countermeasures that could be used for a specific asset. Hypothetical countermeasures could in- clude programmatic or procedural options. The end result is an optimized vulnerabili- ty rating (OVR) associated with the specific target being analyzed. Based on the optimization analysis, the av- erage vulnerability and risk rating can be identified and stated as a percentage. Risk analysis is the aggregation of the threat, target, vulnerability, and optimiza- tion analyses to determine the calculated value of risk associated with a specific as- set that is being targeted by a specific threat.
