Use Amazon GuardDuty and AWS Web Application Firewall to automatically block suspicious hosts

In this blog post, we’ll show you how to use Amazon GuardDuty to automatically update the AWS Web Application Firewall to automatically block suspicious hosts Web Access Control Lists (WebACLs) and VPC Network Access Control Lists (NACLs) in response to GuardDuty findings. After GuardDuty detects a suspicious activity, the solution updates these resources to block communication from the suspicious host while you perform additional investigation and remediation. Once communication has been blocked, further occurrences of a finding are reduced, allowing security and operations teams to focus more on higher priority tasks....
