SQS Encryption Disabled

sqs-encryption-disabled

What this rule checks

Detects SQS queues without encryption.

How to fix it

  1. 1Enable server-side encryption with KMS
  2. 2Use SQS-managed keys (SSE-SQS) or customer managed keys
Flagged`QueueEncryption.UNENCRYPTED` produces an AWS::SQS::Queue with neither `KmsMasterKeyId` nor `SqsManagedSseEnabled: true`, so message data is stored unencrypted. The check flags a queue only when both encryption modes are absent (HIGH, Security).
import * as sqs from 'aws-cdk-lib/aws-sqs';

// inside your Stack
new sqs.Queue(this, 'Queue', {
  encryption: sqs.QueueEncryption.UNENCRYPTED,
});
Fixed`QueueEncryption.KMS_MANAGED` sets `KmsMasterKeyId` (alias/aws/sqs) on the queue, satisfying the at-rest encryption requirement. `QueueEncryption.SQS_MANAGED` (which sets `SqsManagedSseEnabled: true`) is equally accepted and also clears the finding.
import * as sqs from 'aws-cdk-lib/aws-sqs';

// inside your Stack
new sqs.Queue(this, 'Queue', {
  encryption: sqs.QueueEncryption.KMS_MANAGED,
});

Intentional? Suppress this finding

Sometimes a flag is deliberate โ€” a genuinely public endpoint, say. You can dismiss sqs-encryption-disabled and the reason is kept in the report, not silently hidden.

In .cdk-insights.json:

{
  "ignoreRules": [
    { "id": "sqs-encryption-disabled", "reason": "Why this is intentional" }
  ]
}

Or inline in your CDK code:

Validations.of(scope).acknowledge({
  id: 'cdk-insights::sqs-encryption-disabled',
  reason: 'Why this is intentional',
});

Use the rule ID sqs-encryption-disabled shown above โ€” not the CDK-* ID from SARIF / GitHub code scanning. To dismiss every finding on one construct instead, use ignorePaths. Suppression docs โ†’
