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

Example

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import { aws_ssm as ssm } from 'aws-cdk-lib';

Properties

Name	Type	Description
approveAfterDays?	`number`	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.
approveUntilDate?	`string`	The cutoff date for auto approval of released patches.
complianceLevel?	`string`	A compliance severity level for all approved patches in a patch baseline.
enableNonSecurity?	`boolean \|` `IResolvable`	For managed nodes identified by the approval rule filters, enables a patch baseline to apply non-security updates available in the specified repository.
patchFilterGroup?	`IResolvable` `\|` `PatchFilterGroupProperty`	The patch filter group that defines the criteria for the rule.

approveAfterDays?

Type: number (optional)

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.

Patch Manager evaluates patch release dates using Coordinated Universal Time (UTC). If the day represented by 7 is 2025-11-16 , patches released between 2025-11-16T00:00:00Z and 2025-11-16T23:59:59Z will be included in the approval.

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.

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 .

approveUntilDate?

Type: string (optional)

The cutoff date for auto approval of released patches.

Any patches released on or before this date are installed automatically.

Enter dates in the format YYYY-MM-DD . For example, 2025-11-16 .

Patch Manager evaluates patch release dates using Coordinated Universal Time (UTC). If you enter the date 2025-11-16 , patches released between 2025-11-16T00:00:00Z and 2025-11-16T23:59:59Z will be included in the approval.

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

complianceLevel?

Type: string (optional)

A compliance severity level for all approved patches in a patch baseline.

Valid compliance severity levels include the following: UNSPECIFIED , CRITICAL , HIGH , MEDIUM , LOW , and INFORMATIONAL .

enableNonSecurity?

Type: boolean | IResolvable (optional, default: false)

For managed nodes identified by the approval rule filters, enables a patch baseline to apply non-security updates available in the specified repository.

The default value is false . Applies to Linux managed nodes only.

patchFilterGroup?

Type: IResolvable | PatchFilterGroupProperty (optional)

The patch filter group that defines the criteria for the rule.
