How do I write an encrypted SQS policy statement for S3 events?
I have an SQS that is used to have the following policy document. to receive S3 events from a bucket:
{
"Version": "2008-10-17",
"Id": "example-ID",
"Statement": [
{
"Sid": "example-statement-ID",
"Effect": "Allow",
"Principal": {
"AWS": "*"
},
"Action": [
"sqs:SendMessage",
"sqs:ReceiveMessage"
],
"Resource": "arn:aws:sqs:us-east-1:<>:cypher-queue",
"Condition": {
"ArnLike": {
"aws:SourceArn": "arn:aws:s3:*:*:cypher-secondarybucket"
}
}
}
]
}
I have now enabled Server Side Encryption (SSE) for the queue. And I followed this document for writing a policy instruction for encryption. The policy statement now looks like this:
{
"Version": "2008-10-17",
"Id": "example-ID",
"Statement": [
{
"Sid": "example-statement-ID",
"Effect": "Allow",
"Principal": {
"AWS": "*"
},
"Action": [
"sqs:SendMessage",
"sqs:ReceiveMessage"
],
"Resource": "arn:aws:sqs:us-east-1:<>:cypher-queue",
"Condition": {
"ArnLike": {
"aws:SourceArn": "arn:aws:s3:*:*:cypher-secondarybucket"
}
}
},
{
"Effect": "Allow",
"Action": [
"kms:GenerateDataKey",
"kms:Decrypt"
],
"Resource": "arn:aws:sqs:us-east-1:<>:cypher-queue",
"Condition": {
"ArnLike": {
"aws:SourceArn": "arn:aws:s3:*:*:cypher-secondarybucket"
}
}
},
{
"Effect": "Allow",
"Principal": {
"AWS": "*"
},
"Action": "sqs:SendMessage",
"Resource": "arn:aws:sqs:us-east-1:<>:cypher-queue",
"Condition": {
"ArnLike": {
"aws:SourceArn": "arn:aws:s3:*:*:cypher-secondarybucket"
}
}
}
]
}
But now the queue doesn't receive any messages from the bucket when adding files. Is there something wrong that I did with the permissions?

I missed the next announcement of the same article . A very stupid mistake on my part. We'll have to wait for S3 events to be sent to encrypted SQS.
The following AWS service features are not currently compatible with encrypted queues:
Amazon CloudWatch Events
Amazon S3 Event Notifications
Amazon SNS Topic Subscription
Lifecycle hooks auto scaling
AWS IoT Rule Actions
AWS Lambda Dead-Letter Queues
