Actions defined by Amazon EC2 Instance Connect

You can specify the following actions in the Action element of an IAM policy statement. Use policies to grant permissions to perform an operation in Amazon. When you use an action in a policy, you usually allow or deny access to the API operation or CLI command with the same name. However, in some cases, a single action controls access to more than one operation. Alternatively, some operations require several different actions.
