AWS Certified Security – Specialty (SCS-C03) — Question 5

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?

Answer options

• 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 mailiing 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.
• D. Install the AWS Systems Manager Agent (SSM Agent) on all EKS nodes. Configure Amazon CloudWatch Logs lo 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 now audit logs are generated.

Correct answer: C

Explanation

The correct answer is C because it utilizes Amazon GuardDuty, which specifically provides threat detection and monitoring for EKS. This solution includes the necessary components to alert the security team via SNS. Options A and B do not focus on GuardDuty, which is essential for the specified requirements, while D does not effectively address the need for real-time threat detection and alerting.
