🛡️ AWS SNS Topic is not encrypted with a KMS key🟢

Description​

Open File

Description​

This policy identifies AWS SNS Topics that are not configured with server-side encryption (SSE) using an AWS KMS key.

Rationale​

Enabling server-side encryption for SNS topics protects message data stored at rest. Using an AWS KMS key provides centralized key management, including rotation, access control, and auditing, helping to maintain compliance with organizational and regulatory data protection standards.

Audit​

This policy flags an SNS Topic as INCOMPLIANT if the KMS Key ID field is empty.

Enable Server-Side Encryption for SNS Topics Using KMS Keys​

From Command Line​

To enable server-side encryption for an SNS topic using an AWS KMS key, run the following command:

aws sns set-topic-attributes \
    --topic-arn {{topic-arn}} \
    --attribute-name KmsMasterKeyId \
    --attribute-value {{kms-key-id}}
Additional Considerations​

Include the following in the key policy to allow Amazon SNS to encrypt and decrypt messages:

{ 
    "Effect": "Allow", 
    "Principal": { 
        "Service": "sns.amazonaws.com" 
     },
    "Action": [
        "kms:Decrypt",
        "kms:GenerateDataKey"
    ],
    "Resource": "*",
    "Condition": {
        "ArnLike": { 
            "aws:SourceArn": "arn:aws:{{service}}:{{region}}:{{account-id}}:{{resource-type}}/{{resource-id}}" 
        },
        "StringEquals": { 
            "kms:EncryptionContext:aws:sns:topicArn": "arn:aws:sns:{{region}}:{{account-id}}:{{sns-topic-name}}" 
        }
    }
}
