Customize patching in Accelerate
Patching ensures that your software is up-to-date and meets your compliance policies.
When to patch: Patching occurs during a maintenance window. You can schedule maintenance windows so that patches are only applied during preset times.
What to patch: You have to associate the Amazon EC2 instances you want to patch with a maintenance window. To associate the instances with a maintenance window, the Amazon EC2 instances must be tagged, and the maintenance window should have those tags as a target.
Which patches to install: Using patch baselines, you set rules to auto-approve certain types of patches, such as operating system or high-severity patches. You can also specify exceptions to your rules, for example, lists of patches that are always approved or rejected.
