12.2 Deploying Patches in a Controlled Way

To deploy a patch, you can use the Deploy Remediation Wizard. For more information, see Section 6.0, Using the Deploy Remediation Wizard.

Patches are released frequently, and it is possible to automate the entire release process by using the deployment settings. Whilst this may suit some smaller companies, in a large organization with multiple platforms and sites, we recommend that the PVG designs a strategy for deployment. Each patch for each software update will behave differently, which is why it is necessary to control the process. For example, some software will require a reboot after updating, and although Zenworks 11 SP2 can manage this process on your behalf, your PVG should determine the details of this, and be aware of any other software or processes which are running, or patches that are being installed concurrently. The Best Practice recommendation for controlling these processes is to used a phased approach.

Implementing patch management tools in phases allows process and user communication issues to be addressed with a small group before deploying the patch application universally. Most organizations deploy patch management tools first to standardized desktop systems and single-platform server farms of similarly configured servers. Once this has been accomplished, organizations should address the more difficult issue of integrating multi-platform environments, nonstandard desktop systems, legacy computers, and computers with unusual configurations. Manual methods may need to be used for operating systems and applications not supported by automated patching tools, as well as some computers with unusual configurations; examples include embedded systems, industrial control systems, medical devices, and experimental systems. For such computers, there should be a written and implemented procedure for the manual patching process, and the PVG should coordinate local administrator efforts
