Explanation
Encryption should be forced for Kafka clusters, including for communication between nodes. This ensure sensitive data is kept private.
Insecure Example
The following example will fail the AWS022 check.
resource "aws_msk_cluster" "bad_example" {
encryption_info {
encryption_in_transit {
client_broker = "TLS_PLAINTEXT"
in_cluster = true
}
}
}Secure Example
The following example will pass the AWS022 check.
resource "aws_msk_cluster" "good_example" {
encryption_info {
encryption_in_transit {
client_broker = "TLS"
in_cluster = true
}
}
}
