# EC2 instances managed by SSM should have a compliant patch status
 
## Description{% #description %}

This control verifies the status of Systems Manager patch compliance, ensuring that patch installations on EC2 instances are successful. If there are any patch compliance events with a status of `NON_COMPLIANT`, the control will fail. This check applies only to EC2 instances managed by Systems Manager Patch Manager.

Keeping your EC2 instances patched according to organizational requirements helps to minimize the attack surface within your AWS accounts.
