+## AWS managed policy: AmazonEKSConnectorServiceRolePolicy
+
+You can’t attach `AmazonEKSConnectorServiceRolePolicy` to your IAM entities. This policy is attached to a service-linked role that allows Amazon EKS to perform actions on your behalf. For more information, see [Using roles to connect a Kubernetes cluster to Amazon EKS](./using-service-linked-roles-eks-connector.html).
+
+The role allows Amazon EKS to connect Kubernetes clusters. The attached policies allow the role to manage necessary resources to connect to your registered Kubernetes cluster.
+
+**Permissions details**
+
+This policy includes the following permissions that allow Amazon EKS to complete the following tasks.
+
+  * **`SSM Management` ** – Create, describe, and delete SSM activations, and deregister managed instances. This allows basic Systems Manager operations.
+
+  * **`Session Management` ** – Start SSM sessions specifically for EKS clusters and execute non-interactive commands using the AmazonEKS document.
+
+  * **`IAM Role Passing` ** – Pass IAM roles specifically to the SSM service, controlled by a condition that restricts the passed roles to `ssm.amazonaws.com`.
+
+  * **`EventBridge Rules` ** – Create EventBridge rules and targets, but only when managed by `eks-connector.amazonaws.com`. Rules are specifically limited to AWS SSM as the event source.
