DBS-C01 Database Security Practice Question
An application uses an Amazon RDS for MySQL database. The security team requires that all traffic to the database be encrypted in transit. Which configuration ensures this?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create a custom DB parameter group with the require_secure_transport parameter set to ON.
Setting require_secure_transport to ON in a custom DB parameter group enforces SSL/TLS for all connections to the RDS MySQL database, ensuring encryption in transit. Option A is wrong because the default parameter group does not enforce SSL. Option C is wrong because security groups control network access at the port level, not encryption. Option D is wrong because network ACLs are stateless and do not enforce encryption.
