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?
Option C best meets the requirements because Amazon GuardDuty provides Kubernetes-focused threat detection for Amazon EKS by analyzingEKS control plane audit logs(EKS Protection) and combining that signal withruntime telemetryfrom the worker nodes (Runtime Monitoring). EKS audit logs capture Kubernetes API activity and authorization decisions, allowing GuardDuty to detect suspicious cluster actions such as unusual API calls, unexpected access patterns, or indicators of compromise within the cluster. Runtime Monitoring extends coverage tooperating system/process activity, network connections, and file activityon the nodes, which directly aligns with the need to monitor OS, networking, and file events in addition to audit logs.
For notifications, GuardDuty generatesfindingsthat can be delivered throughAmazon EventBridgerules. EventBridge can route relevant GuardDuty findings to anAmazon SNS topic, and SNS can sendemail alertsto the security team by subscribing the team's mailing list to the topic. This approach is fully managed, near real time, and avoids building custom log-parsing pipelines while still providing actionable alerts based on GuardDuty's curated EKS threat detections.
