Which AWS service will meet these requirements?

Explanations:

Amazon GuardDuty is a threat detection service that continuously monitors for malicious activity and unauthorized behavior in AWS accounts and workloads. It does not provide web traffic filtering capabilities.

AWS WAF (Web Application Firewall) is specifically designed to protect web applications from common web exploits and allows users to create custom rules to filter and control inbound web traffic based on specified conditions.

Amazon Macie is a data security and privacy service that uses machine learning to automatically discover, classify, and protect sensitive data stored in AWS. It is not focused on controlling inbound web traffic.

AWS Shield is a managed DDoS protection service that safeguards applications running on AWS. While it helps protect against DDoS attacks, it does not offer the ability to filter and control inbound web traffic based on custom conditions.
