enable-bucket-encryption
Explanation
S3 Buckets should be encrypted with customer managed KMS keys and not default AWS managed keys, in order to allow granular control over access to specific buckets.
Possible Impact
The bucket objects could be read if compromised
Suggested Resolution
Configure bucket encryption
Insecure Example
The following example will fail the aws-s3-enable-bucket-encryption check.
resource "aws_s3_bucket" "bad_example" {
bucket = "mybucket"
}
Secure Example
The following example will pass the aws-s3-enable-bucket-encryption check.
resource "aws_s3_bucket" "good_example" {
bucket = "mybucket"
server_side_encryption_configuration {
rule {
apply_server_side_encryption_by_default {
kms_master_key_id = "arn"
sse_algorithm = "aws:kms"
}
}
}
}
