Ensure that RDS instance requires all incoming connections to use SSL

高レベル 1自動alibaba

説明

It is recommended to enforce all incoming connections to SQL database instance to use SSL. SQL database connections if successfully trapped (MITM); can reveal sensitive data like credentials, database queries, query outputs etc. DescribeDBInstanceSSL must report SSLEnabled Yes/on for every instance. Iterates every RDS region and instance (DescribeDBInstances). Read-only aliyun CLI calls; credentials and default region come from the CLI's normal profile (aliyun configure, ~/.aliyun/config.json or ALIBABA_CLOUD_* environment variables). JSON output is parsed with sed/awk. A missing CLI or credential fails the check.

修正方法

修正方法: ガイダンスまたは IaC パッチ

aliyun rds ModifyDBInstanceSSL --DBInstanceId <id> --ConnectionString <endpoint> --SSLEnabled 1 (RDS console > Data Security > SSL Encryption), and require TLS in the database engine.
