Ensure Encryption Key Rotation Is Configured

보통레벨 2수동 검토tdsql

설명

Encryption master keys should be rotated periodically. TDSQL supports master key rotation via ALTER INSTANCE ROTATE INNODB MASTER KEY, which generates a new key version and re-wraps all data encryption keys (DEKs) using the envelope encryption model-without requiring data re-encryption. Assessed manually here: the benchmark check is environment-specific and cannot be evaluated reliably by a single command.

Run SELECT * FROM performance_schema.keyring_keys ORDER BY KEY_ID DESC LIMIT 5; and SHOW GLOBAL STATUS LIKE 'Innodb_encryption_master_key_id'; then review KMS audit logs. The master key must have been rotated within the policy period (e.g. within the last 365 days); no rotation within the period is a finding.

조치 방법

조치 방식: 가이드 또는 인프라 패치

1. Perform immediate key rotation: ALTER INSTANCE ROTATE INNODB MASTER KEY; 2. Verify rotation success: SHOW GLOBAL STATUS LIKE 'Innodb_encryption_master_key_id'; -- The key ID should increment after rotation 3. Establish a periodic rotation schedule (recommended: every 90-365 days) via operational procedures or automation.
