The software version is the component of a software inventory that best enables the identification and mitigation of known vulnerabilities. The software version is the specific release or update of a software product that has a unique identifier, such as a number or a name. The software version indicates the features, functions, and security patches that are included in the software product. By knowing the software version, the organization can compare it with the latest available version and identify any missing or outdated security fixes. The organization can then mitigate the known vulnerabilities by updating or upgrading the software to the latest version. The other components of a software inventory, such as the assigned software manager, the software support contract expiration, and the software licensing information, are not as directly related tothe identification and mitigation of known vulnerabilities, although they may provide some contextual or administrative information. References = Risk and Information Systems Control Study Manual, Chapter 2, Section 2.3.2, page 2-25.
