Ensure that RDS instance requires all incoming connections to use SSL

높음레벨 1자동alibaba

설명

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.
