AWS WAF Overview:

AWS Web Application Firewall (WAF) allows users to create rules to block or allow traffic based on IP addresses, request patterns, and other conditions.

It is ideal for blocking traffic from a specific IP address.

Why AWS WAF Meets the Requirement:

The company can create a WAF rule to block traffic from the malicious IP address.

WAF integrates with services like Amazon CloudFront, Application Load Balancer, and API Gateway.

Why Other Options Are Incorrect:

A. AWS Shield:Protects against DDoS attacks but does not allow custom IP blocking.

B. AWS Config:Monitors resource configurations but does not block IPs.

C. Amazon GuardDuty:Detects threats but does not block traffic directly.
