Automated Security Response on AWS is an add-on that works with AWS Security Hub and provides predefined response and remediation actions based on industry compliance standards and best practices for security threats. When using Security Hub, this AWS Solution can help you fix common security problems while improving your overall security on AWS.
This solution creates playbooks for you to individually choose what you want to deploy in your Security Hub admin account. Each playbook contains the necessary actions to start the remediation workflow within the admin account or any member account.
Initiate remediations and findings using custom actions in the Security Hub console.
Configure AWS Foundations Benchmarks or AWS Foundational Security Best Practices.
Deploy a predefined set of response and remediation actions to respond to threats automatically.
Extend this solution with custom remediation and playbook implementations. Or, deploy a custom playbook for a new set of controls.
1. Detect: Security Hub provides you with a comprehensive view of their AWS security state. It helps you to measure your environment against security industry standards and best practices. It works by collecting events and data from other AWS services, such as AWS Config, Amazon GuardDuty, and AWS Firewall Manager.
These events and data are analyzed against security standards, such as CIS AWS Foundations Benchmark. Exceptions are asserted as findings in the Security Hub console. New findings are sent as Amazon EventBridge.
2. Initiate: You can initiate events against findings using custom actions, which result in Amazon EventBridge Events. AWS Security Hub Custom Actions and Amazon EventBridge rules initiate Automated Security Response on AWS playbooks to address findings. One EventBridge rule is deployed to match the custom action event, and one EventBridge Event Rule is deployed for each supported control (deactivated by default) to match the real-time finding event.
You can use the Security Hub Custom Action menu to initiate automated remediation, or after careful testing in a non-production environment, you can activate automated remediations. This can be activated per remediation—it is not necessary to activate automatic initiations on all remediations.
On the Security Hub dashboard, the finding workflow status is changed from NEW to either NOTIFIED or RESOLVED on the Security Hub dashboard. The security finding notes are updated to reflect the remediation performed.
