Connect Policy Examples

The following policy grants permission to connect to AWS IoT with client id "client1":

{ "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": [ "iot:Connect" ], "Resource": [ "arn:aws:iot:us-east-1:123456789012:client/client1" ] } ] }

The following policy denies permission to connect to AWS IoT with client ids "client1" and "client2", while allowing devices to connect using a client id that matches the name of a thing registered in the AWS IoT Registry:

{ "Version": "2012-10-17", "Statement": [ { "Effect": "Deny", "Action": [ "iot:Connect" ], "Resource": [ "arn:aws:iot:us-east-1:123456789012:client/client1", "arn:aws:iot:us-east-1:123456789012:client/client2" ] }, { "Effect": "Allow", "Action": [ "iot:Connect" ], "Resource": [ "arn:aws:iot:us-east-1:123456789012:client/${iot:Connection.Thing.ThingName}" ] } ] }

For devices registered as things in the AWS IoT Registry and that hold the certificate associated with thing named, the following policy grants permission to connect using the thing name as the client id and to subscribe to topic filter foo/bar:

{ "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": [ "iot:Connect" ], "Resource": [ "arn:aws:iot:us-east-1:123456789012:client/${iot:Connection.Thing.ThingName}" ] }, { "Effect": "Allow", "Action": [ "iot:Subscribe" ], "Resource": [ "arn:aws:iot:us-east-1:123456789012:topicfilter/foo/bar" ] } ] }
unregistered devices (3)

For devices not registered as things in the AWS IoT Registry, the following policy grants permission to connect using client id "client1" and to subscribe to topic filter foo/bar:

{ "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": [ "iot:Connect" ], "Resource": [ "arn:aws:iot:us-east-1:123456789012:client/client1" ] }, { "Effect": "Allow", "Action": [ "iot:Subscribe" ], "Resource": [ "arn:aws:iot:us-east-1:123456789012:topicfilter/foo/bar" ] } ] }
