In this blog post, we’ll show you how to use AWS Network Firewall to automatically respond to potential security events within your Amazon Web Services (AWS) environment that are detected by Amazon GuardDuty. The goal is to rapidly contain the impact of security events, while providing additional time for follow-up investigation. By coding the response steps using services like AWS Lambda and AWS Step Functions, your response time can be reduced down to minutes or even seconds....

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....

In this post, I show you how to deploy a sample custom Alexa skill and use an Alexa-enabled device, such as Amazon Echo, to get information about GuardDuty findings across your AWS accounts and regions. The information provided by this sample skill gives you a broad overview of GuardDuty finding statistics, severities, and descriptions. When you hear something interesting, you can log in to the GuardDuty console or another analysis tool to investigate the findings data....
