Exam AWS-SysOps topic 1 question 890 discussion

Exam question from Amazon's AWS-SysOps
Question #: 890
Topic #: 1
[All AWS-SysOps Questions]

A company that hosts a multi-tier ecommerce web application on AWS has been alerted to suspicious application traffic. The architecture consists of Amazon EC2 instances deployed across multiple Availability Zones behind an Application Load Balancer (ALB). After examining the instance logs, a SysOps administrator determines that the suspicious traffic is an attempted SQL injection attack.
What should the SysOps administrator do to prevent similar attacks?

  • A. Create an Amazon CloudFront distribution with the ALB as the origin. Enable AWS Shield Advanced to protect from SQL injection attacks at edge locations.
  • B. Create an AWS WAF web ACL, and configure a SQL injection rule to add to the web ACL. Associate the WAF web ACL with the ALB.
  • C. Enable Amazon GuardDuty. Use Amazon EventBridge (Amazon CloudWatch Events) to trigger an AWS Lambda function every time GuardDuty detects SQL injection.
  • D. Install Amazon Inspector on the EC2 instances, and configure a rules package. Use the findings reports to identify and block SQL injection attacks.

Selected Answer: B
AWS Web Application Firewall (WAF) is a security service that helps protect web applications from common web exploits and attacks, including SQL injection attacks. By creating a web ACL (Access Control List) and configuring a SQL injection rule to add to the web ACL, you can define custom rules to inspect incoming requests to the Application Load Balancer (ALB) and block any requests that contain SQL injection patterns.
