Which AWS service helps to automate and manage security across hybrid and multicloud environments?

The correct choice is AWS Systems Manager, which is designed to provide operational data and automate management across applications and resources in hybrid and multicloud environments. This service enables you to automate various tasks like patch management, configuration management, and compliance checks for your entire fleet of AWS resources, as well as on-premises and other cloud-based resources.

AWS Systems Manager integrates with various AWS services and provides a unified view of your resources, allowing for easier management and improved security automation. With capabilities like run command, patch manager, and automation documents, it allows for streamlined workflows for security compliance and operational tasks, which are essential for maintaining security across diverse environments.

The other options, while useful, address different needs: AWS Config focuses on tracking AWS resource configurations and compliance, AWS Organizations is used for managing multiple AWS accounts more effectively, and the AWS Command Line Interface provides a way to interact with AWS services through command line prompts but does not inherently automate or manage security.
