Amazon managed policies for CloudWatch Network Monitor

To add permissions to users, groups, and roles, it is easier to use Amazon managed policies than to write policies yourself. It takes time and expertise to create IAM customer managed policies that provide your team with only the permissions they need. To get started quickly, you can use our Amazon managed policies. These policies cover common use cases and are available in your Amazon account. For more information about Amazon managed policies, see Amazon managed policies in the IAM User Guide.

Amazon services maintain and update Amazon managed policies. You can't change the permissions in Amazon managed policies. Services occasionally add additional permissions to an Amazon managed policy to support new features. This type of update affects all identities (users, groups, and roles) where the policy is attached. Services are most likely to update an Amazon managed policy when a new feature is launched or when new operations become available. Services do not remove permissions from an Amazon managed policy, so policy updates won't break your existing permissions.

Additionally, Amazon supports managed policies for job functions that span multiple services. For example, the ReadOnlyAccess Amazon managed policy provides read-only access to all Amazon services and resources. When a service launches a new feature, Amazon adds read-only permissions for new operations and resources. For a list and descriptions of job function policies, see Amazon managed policies for job functions in the IAM User Guide.

Amazon managed policy: CloudWatchNetworkMonitorServiceRolePolicy

The CloudWatchNetworkMonitorServiceRolePolicy is attached to a service-linked role that allows the service to perform actions on your behalf and access resources associated with CloudWatch Network Monitor. You cannot attach this policy to your IAM identities. For more information, see Using a service-linked role for CloudWatch Network Monitor.
