AWS Certified Security – Specialty (SCS-C02) — Question 44
A company is building an application on AWS that will store sensitive information. The company has a support team with access to the IT infrastructure, including databases. The company’s security engineer must introduce measures to protect the sensitive data against any data breach while minimizing management overhead. The credentials must be regularly rotated.
What should the security engineer recommend?
Answer options
- A. Enable Amazon RDS encryption to encrypt the database and snapshots. Enable Amazon Elastic Block Store (Amazon EBS) encryption on Amazon EC2 instances. Include the database credential in the EC2 user data field. Use an AWS Lambda function to rotate database credentials. Set up TLS for the connection to the database.
- B. Install a database on an Amazon EC2 instance. Enable third-party disk encryption to encrypt the Amazon Elastic Block Store (Amazon EBS) volume. Store the database credentials in AWS CloudHSM with automatic rotation. Set up TLS for the connection to the database.
- C. Enable Amazon RDS encryption to encrypt the database and snapshots. Enable Amazon Elastic Black Store (Amazon EBS) encryption on Amazon EC2 instances. Store the database credentials in AWS Secrets Manager with automatic rotation. Set up TLS for the connection to the RDS hosted database.
- D. Set up an AWS CloudHSM cluster with AWS Key Management Service (AWS KMS) to store KMS keys. Set up Amazon RDS encryption using AWS KMS to encrypt the database. Store database credentials in the AWS Systems Manager Parameter Store with automatic rotation. Set up TLS for the connection to the RDS hosted database.
Correct answer: C
Explanation
Option C is correct because it utilizes Amazon RDS encryption and AWS Secrets Manager, which automatically rotates credentials, ensuring both security and ease of management. Option A includes EC2 user data which is less secure for credential storage. Option B suggests third-party disk encryption which adds complexity without leveraging AWS native services effectively. Option D uses AWS Systems Manager Parameter Store, but Secrets Manager is better suited for credential management and rotation.
