AWS Systems Manager is the operations hub for AWS, allowing you to manage your infrastructure with ease. Systems Manager OpsCenter helps IT operators and DevOps engineers diagnose and resolve operational issues related to AWS resources in a central location, and Systems Manager Explorer is an operations dashboard that provides a view of your operations data across your AWS accounts and Regions. Security and compliance professionals and DevOps engineers use Security Hub to continuously monitor and improve the security posture of their AWS accounts and resources.
Most customers separate their security issues (e.g., Amazon S3 buckets publicly accessible or crypto-mining detected on Amazon EC2 instances) and operational issues (e.g., underutilized Amazon Redshift instances or over-utilized Amazon EC2 instances) because security issues are sensitive and typically have different access requirements. As a result, they use Security Hub to understand, manage, and remediate their security issues, and they use Systems Manager to understand, manage, and remediate their operational issues. We also recommend that you use Security Hub for more specialized views into your security posture.
When the same engineers work on both security and operational issues, it can help to consolidate them in a single location. You can do that by opting in for findings to be sent to OpsCenter and Explorer where engineers can investigate and remediate security issues alongside operational issues via Systems Manager Automation runbooks.
