IAM policy for authenticated user for IoT

Question

Following AWS doc link talks about IAM policy for  authenticated role for publisher.

https://docs.aws.amazon.com/iot/latest/developerguide/cog-iot-policies.html

But what will the authenticated IAM policy for subscriber? This is not given in the docs.

Isaac · Answer

Something like this would work to allow for the device to subscribe to a specific  topic

```
{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": [
                "iot:Connect"
            ],
            "Resource": [
                "arn:aws:iot:us-east-1:123456789012:client/clientId1",
                "arn:aws:iot:us-east-1:123456789012:client/clientId2",
                "arn:aws:iot:us-east-1:123456789012:client/clientId3"
            ]
        },
        {
            "Effect": "Allow",
            "Action": [
                "iot:Subscribe"
            ],
            "Resource": [
                "arn:aws:iot:us-east-1:123456789012:topicfilter/some_specific_topic"
            ]
        },
        {
            "Effect": "Allow",
            "Action": [
                "iot:Receive"
            ],
            "Resource": [
                "arn:aws:iot:us-east-1:123456789012:topic/some_specific_topic"
            ]
        }
    ]
}
