Management of Patch and System Update Guidelines

Audience:

All parties responsible for the maintenance of applications and systems.

Policy Statement:

Asset Owners and the supporting organization must take timely and appropriate action in the identification of relevant patches and system updates to ensure the ongoing functionality of systems and applications, and to minimize the risk of exploitation of recognized and announced vulnerabilities. Implementation of these guidelines will help to better manage risk by:

  • Obtaining timely information about updates and technical vulnerabilities of information systems and applications;
  • Evaluating the value of the patch or update in terms of functionality, problem resolution, prerequisite installation, vulnerability avoidance or reduction, vendor recommendations or requirements, potential impact to systems and/or users, etc.; and
  • Implementing appropriate measures to address any identified risk.
