DescribeCanaries

This operation returns a list of the canaries in your account, along with full details about each canary.

This operation does not have resource-level authorization, so if a user is able to use DescribeCanaries, the user can see all of the canaries in the account. A deny policy can only be used to restrict access to all canaries. It cannot be used on specific resources.
