AWS::SSM::PatchBaseline Rule

The Rule property type specifies an approval rule for a Systems Manager patch baseline.

The PatchRules property of the RuleGroup property type contains a list of Rule property types.

Syntax

To declare this entity in your AWS CloudFormation template, use the following syntax:

JSON

{
  "ApproveAfterDays" : Integer,
  "ApproveUntilDate" : String,
  "ComplianceLevel" : String,
  "EnableNonSecurity" : Boolean,
  "PatchFilterGroup" : PatchFilterGroup
}

Properties

ApproveAfterDays

The number of days after the release date of each patch matched by the rule that the patch is marked as approved in the patch baseline. For example, a value of 7 means that patches are approved seven days after they are released.

This parameter is marked as Required: No, but your request must include a value for either ApproveAfterDays or ApproveUntilDate.

Not supported for Debian Server or Ubuntu Server.

Important

Use caution when setting this value for Windows Server patch baselines. Because patch updates that are replaced by later updates are removed, setting too broad a value for this parameter can result in crucial patches not being installed. For more information, see the Windows Server tab in the topic How security patches are selected in the AWS Systems Manager User Guide.

Required: No
