Abstract
Each year, thousands of new software vulnerabilities are reported, and affected organizations must analyze them and decide how to respond. Many organizations employ ad hoc systems of decision making, which often result in inconsistent decisions that do not properly reflect the concerns of the organization at large. VRDA (Vulnerability Response Decision Assistance) allows organizations to leverage the analysis effort at other organizations and to structure decision-making. VRDA enables organizations to spend less time analyzing vulnerabilities in which they are not interested, to make decisions more consistently, and to structure their decision making to better align with the goals of the organization. VRDA consists of a data exchange format, a decision making model, a decision model creation technique, and a tool embodying these concepts. One response team is employing a basic form of VRDA to cut the number of vulnerabilities analyzed by a factor of two. Another response team is developing and testing a VRDA implementation within their organization.
