+## AWS Systems Patch Manager
+
+AWS Systems Patch Manager automates patching for operating systems and applications on your EC2 instances.
+
+###### To configure the patch manager, perform the following steps:
+
+  1. Enable Systems Manager:
+
+    1. Attach the `AmazonSSMManagedInstanceCore` IAM policy to your EC2 instance role.
+
+    2. Ensure SSM Agent is installed (default for Amazon Linux 2, Ubuntu 20.04+ AMIs).
+
+  2. Create a patch baseline by defining rules for critical/security updates, including schedules for patch application.
+
+  3. Schedule updates for applying patches at a defined time by using maintenance windows in SSM.
+
+  4. Verify compliance by checking patching status and compliance reports in the Systems Manager.
