Which AWS service will meet these requirements?

Explanations:

Amazon CloudWatch is primarily a monitoring service that provides data and insights about AWS resources, but it does not govern or control access to those resources. It focuses on performance metrics and logging rather than compliance enforcement.

AWS Service Catalog enables organizations to create and manage catalogs of IT services that are approved for use on AWS. It allows for governance and control over who can deploy, manage, and decommission AWS resources, aligning with organizational business standards.

Amazon GuardDuty is a threat detection service that continuously monitors for malicious activity and unauthorized behavior, but it does not provide governance capabilities over resource deployment and management. It is focused on security monitoring rather than compliance enforcement.

AWS Security Hub is a security service that provides a comprehensive view of security alerts and compliance status across AWS accounts. However, it does not control or govern the deployment and management of AWS resources, making it less suitable for enforcing compliance with business standards.
