Automate the update process and audit its effectiveness
Automating updates increases the percentage of successful installations of patches, improves the speed of deployment and frees up staff time. Audits can be used to verify the results.
Automating updates frees up staff time to perform compatibility tests and to monitor deployment. It also guarantees comprehensive reporting of the resources updated with and without success, of resources not connected to the network, etc. Use WSUS (Windows Server Update Services) or an equivalent to automate the update process.
