Question # 3

A company is operating an open-source software platform that is internet facing. Thelegacy software platform no longer receives security updates. The software platformoperates using Amazon Route 53 weighted load balancing to send traffic to two AmazonEC2 instances that connect to an Amazon RDS cluster. A recent report suggests thissoftware platform is vulnerable to SQL injection attacks, with samples of attacks provided.The company’s security engineer must secure this system against SQL injection attackswithin 24 hours. The security engineer’s solution must involve the least amount of effortand maintain normal operations during implementation.What should the security engineer do to meet these requirements?

A. Create an Application Load Balancer with the existing EC2 instances as a target group.Create an AWS WAF web ACL containing rules that protect the application from this attack,then apply it to the ALB.

B. Create an Amazon CloudFront distribution specifying one EC2 instance as an origin.Create an AWS WAF web ACL containing rules that protect the application from this attack,then apply it to the distribution. Test to ensure the vulnerability has been mitigated, thenredirect the Route 53 records to point to CloudFront.
C. Obtain the latest source code for the platform and make the necessary updates. Testthe updated code to ensure that the vulnerability has been mitigated, then deploy thepatched version of the platform to the EC2 instances.
D. Update the security group that is attached to the EC2 instances, removing access fromthe internet to the TCP port used by the SQL database. Create an AWS WAF web ACLcontaining rules that protect the application from this attack, then apply it to the EC2instances.
