A company hosts its public website on Amazon EC2 instances behind an Application Load Balancer (ALB). The website is experiencing a global DDoS attack by a specific IoT device brand that has a unique user agent.

A security engineer is creating an AWS WAF web ACL and will associate the web ACL with the ALB. The security engineer must implement a rule statement as part of the web ACL to block the requests. The rule statement must mitigate the current attack and future attacks from these IoT devices without blocking requests from customers.

Which rule statement will meet these requirements?

  • B. Use a geographic match rule statement. Configure the statement to block countries that the IoT devices are located in.
  • C. Use a rate-based rule statement. Set a rate limit that is equal to the number of requests that are coming from the IoT devices.
  • D. Use a string match rule statement that includes details of the IoT device brand from the user agent.
