Which of the following AWS services can be used to accomplish this?

A new public web application is deployed on AWS that will run behind an Application Load Balancer (ALB). An AWS security expert needs to encrypt the newly deployed application at the edge with an SSL/TLS certificate issued by an external certificate authority. In addition, he needs to ensure the rotation of the certificate yearly before it expires.

Answer: B

Explanation:

AWS Certificate Manager (ACM) is the service that enables an AWS security expert to manage SSL/TLS certificates provided by AWS or an external certificate authority. It allows the deployment of the certificate on AWS services such as an Application Load Balancer (ALB) and also handles the renewal and rotation of certificates.

Here’s how ACM would be used for the web application:

Certificate Provisioning: The security expert can import an SSL/TLS certificate issued by an external certificate authority into ACM.

Integration with ALB: ACM integrates with ALB, allowing the certificate to be easily deployed to encrypt the application at the edge.

Automatic Renewal: ACM can be configured to automatically renew certificates provided by AWS. For certificates from external authorities, the expert can manually import a new certificate before the old one expires.

Yearly Rotation: While ACM does not automatically rotate externally provided certificates, it simplifies the process of replacing them by allowing the expert to import new certificates as needed.

Reference: AWS documentation on ACM, which explains how to import certificates and use them with ALB1. AWS blog post discussing the importance of rotating SSL/TLS certificates and how ACM facilitates this process2.
