Question
A company runs several applications on Amazon Elastic Kubernetes Service (Amazon EKS). The company needs a solution to detect any Kubernetes security risks by monitoring Amazon EKS audit logs in addition to operating system, networking, and file events. The solution must send email alerts for any identified risks to a mailing list that is associated with a security team.
Which solution will meet these requirements?
- A. Deploy AWS Security Hub and enable security standards that contain EKS controls. Create an Amazon Simple Notification Service (Amazon SNS) topic and set the security team's mailing list as a subscriber. Use an Amazon EventBridge rule to send relevant Security Hub events to the SNS topic.
- B. Enable Amazon Inspector container image scanning. Configure Amazon Detective to analyze EKS security logs. Create Amazon CloudWatch log groups for EKS audit logs. Use an AWS Lambda function to process the logs and to send email alerts to the security team.
- C. Enable Amazon GuardDuty. Enable EKS Protection and Runtime Monitoring for Amazon EKS in GuardDuty. Create an Amazon Simple Notification Service (Amazon SNS) topic and set the security team's mailing list as a subscriber. Use an Amazon EventBridge rule to send relevant GuardDuty events to the SNS topic. Correct
- D. Install the AWS Systems Manager Agent (SSM Agent) on all EKS nodes. Configure Amazon CloudWatch Logs to collect EKS audit logs. Create an Amazon Simple Notification Service (Amazon SNS) topic and set the security team's mailing list as a subscriber. Configure a CloudWatch alarm to publish a message to the SNS topic when new audit logs are generated.
Explanation
The correct answer is C because Amazon GuardDuty provides built-in protection for EKS clusters, including runtime monitoring and detection of security risks by analyzing EKS audit logs. By enabling EKS Protection in GuardDuty, creating an SNS topic for the security team's mailing list, and using EventBridge to route relevant GuardDuty findings to this SNS topic, the solution meets the requirement to detect Kubernetes security risks and send email alerts.
