Abstract
Determining appropriate and cost-effective upgrades for safeguards and security (S&S) systems is a demanding activity. The process requires that (1) specific weaknesses be recognized through a vulnerability assessment (VA), (2) candidate upgrades be identified, through analysis of VA results in conjunction with other significant influences, and (3) various upgrade options be evaluated, prioritized, and selected. The goal is to select upgrades that reduce risk to an acceptable level for the lowest cost while minimizing any negative impacts on productivity, safety, environment, etc.
