Glue Job Encryption Missing

What this rule checks

Detects Glue jobs without an attached SecurityConfiguration for encrypting bookmarks, S3 data, and CloudWatch logs.

How to fix it

1. 1Create a SecurityConfiguration enabling KMS encryption for all targets
2. 2Reference it via the job's SecurityConfiguration property

import { CfnJob } from 'aws-cdk-lib/aws-glue';

new CfnJob(this, 'EtlJob', {
  name: 'nightly-etl',
  role: 'arn:aws:iam::111122223333:role/GlueEtlRole',
  command: {
    name: 'glueetl',
    scriptLocation: 's3://my-glue-scripts/nightly-etl.py',
    pythonVersion: '3',
  },
  glueVersion: '4.0',
});

import { CfnJob, CfnSecurityConfiguration } from 'aws-cdk-lib/aws-glue';

const secConfig = new CfnSecurityConfiguration(this, 'GlueSecurityConfig', {
  name: 'etl-encryption',
  encryptionConfiguration: {
    s3Encryptions: [{ s3EncryptionMode: 'SSE-KMS' }],
    cloudWatchEncryption: {
      cloudWatchEncryptionMode: 'SSE-KMS',
      kmsKeyArn: 'arn:aws:kms:us-east-1:111122223333:key/abcd-1234',
    },
    jobBookmarksEncryption: {
      jobBookmarksEncryptionMode: 'CSE-KMS',
      kmsKeyArn: 'arn:aws:kms:us-east-1:111122223333:key/abcd-1234',
    },
  },
});
new CfnJob(this, 'EtlJob', {
  name: 'nightly-etl',
  role: 'arn:aws:iam::111122223333:role/GlueEtlRole',
  command: {
    name: 'glueetl',
    scriptLocation: 's3://my-glue-scripts/nightly-etl.py',
    pythonVersion: '3',
  },
  glueVersion: '4.0',
  securityConfiguration: secConfig.name,
});

Intentional? Suppress this finding

Sometimes a flag is deliberate — a genuinely public endpoint, say. You can dismiss glue-job-encryption-missing and the reason is kept in the report, not silently hidden.

In .cdk-insights.json:

{
  "ignoreRules": [
    { "id": "glue-job-encryption-missing", "reason": "Why this is intentional" }
  ]
}

Or inline in your CDK code:

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

Use the rule ID glue-job-encryption-missing shown above — not the CDK-* ID from SARIF / GitHub code scanning. To dismiss every finding on one construct instead, use ignorePaths. Suppression docs →
