Immediately, I’m glad to announce Amazon GuardDuty Prolonged Risk Detection with expanded protection for Amazon Elastic Kubernetes Service (Amazon EKS), constructing upon the capabilities we launched in our AWS re:Invent 2024 announcement of Amazon GuardDuty Prolonged Risk Detection: AI/ML assault sequence identification for enhanced cloud safety.
Safety groups managing Kubernetes workloads typically wrestle to detect refined multistage assaults that focus on containerized purposes. These assaults can contain container exploitation, privilege escalation, and unauthorized motion inside Amazon EKS clusters. Conventional monitoring approaches may detect particular person suspicious occasions, however typically miss the broader assault sample that spans throughout these completely different knowledge sources and time durations.
GuardDuty Prolonged Risk Detection introduces a brand new crucial severity discovering kind, which routinely correlates safety indicators throughout Amazon EKS audit logs, runtime behaviors of processes related to EKS clusters, malware execution in EKS clusters, and AWS API exercise to establish refined assault patterns that may in any other case go unnoticed. For instance, GuardDuty can now detect assault sequences wherein a menace actor exploits a container software, obtains privileged service account tokens, after which makes use of these elevated privileges to entry delicate Kubernetes secrets and techniques or AWS sources.
This new functionality makes use of GuardDuty correlation algorithms to watch and establish sequences of actions that point out potential compromise. It evaluates findings throughout safety plans and different sign sources to establish widespread and rising assault patterns. For every assault sequence detected, GuardDuty supplies complete particulars, together with probably impacted sources, timeline of occasions, actors concerned, and indicators used to detect the sequence. The findings additionally map noticed actions to MITRE ATT&CK® ways and methods and remediation suggestions primarily based on AWS greatest practices, serving to safety groups perceive the character of the menace.
To allow Prolonged Risk Detection for EKS, you want not less than certainly one of these options enabled: EKS Safety or Runtime Monitoring. For max detection protection, we advocate enabling each to reinforce detection capabilities. EKS Safety screens management aircraft actions by way of audit logs, and Runtime Monitoring observes behaviors inside containers. Collectively, they create a whole view of your EKS clusters, enabling GuardDuty to detect complicated assault patterns.
The way it works
To make use of the brand new Amazon GuardDuty Prolonged Risk Detection for EKS clusters, go to the GuardDuty console to allow EKS Safety in your account. From the Area selector within the upper-right nook, choose the Area the place you need to allow EKS Safety. Within the navigation pane, select EKS Safety. On the EKS Safety web page, assessment the present standing and select Allow. Choose Verify to avoid wasting your choice.
After it’s enabled, GuardDuty instantly begins monitoring EKS audit logs out of your EKS clusters with out requiring any extra configuration. GuardDuty consumes these audit logs immediately from the EKS management aircraft by way of an unbiased stream, which doesn’t have an effect on any present logging configurations. For multi-account environments, solely the delegated GuardDuty administrator account can allow or disable EKS Safety for member accounts and configure auto-enable settings for brand spanking new accounts becoming a member of the group.
To allow Runtime Monitoring, select Runtime Monitoring within the navigation pane. Beneath the Configuration tab, select Allow to allow Runtime Monitoring on your account.
Now, you possibly can view from the Abstract dashboard the assault sequences and important findings particularly associated to Kubernetes cluster compromise. You possibly can observe that GuardDuty identifies complicated assault patterns in Kubernetes environments, equivalent to credential compromise occasions and suspicious actions inside EKS clusters. The visible illustration of findings by severity, useful resource impression, and assault varieties offers you a holistic view of your Amazon EKS safety posture. This implies you possibly can prioritize essentially the most crucial threats to your containerized workloads.
The Discovering particulars web page supplies visibility into complicated assault sequences focusing on EKS clusters, serving to you perceive the complete scope of potential compromises. GuardDuty correlates indicators right into a timeline, mapping noticed behaviors to MITRE ATT&CK® ways and methods equivalent to account manipulation, useful resource hijacking, and privilege escalation. This granular degree of perception reveals precisely how attackers progress by way of your Amazon EKS atmosphere. It identifies affected sources like EKS workloads and repair accounts. The detailed breakdown of indicators, actors, and endpoints supplies you with actionable context to grasp assault patterns, decide impression, and prioritize remediation efforts. By consolidating these safety insights right into a cohesive view, you possibly can shortly assess the severity of Amazon EKS safety incidents, cut back investigation time, and implement focused countermeasures to guard your containerized purposes.
The Sources part of the Discovering particulars web page reveals context concerning the particular property affected throughout an assault sequence. This unified useful resource record supplies you with visibility into the precise scope of the compromise—from the preliminary entry to the focused Kubernetes elements. As a result of GuardDuty consists of detailed attributes equivalent to useful resource varieties, identifiers, creation dates, and namespace info, you possibly can quickly assess which elements of your containerized infrastructure require quick consideration. This centered method eliminates guesswork throughout incident response, so you possibly can prioritize remediation efforts on essentially the most crucial affected sources and reduce the potential blast radius of Amazon EKS focused assaults.
Now obtainable
Amazon GuardDuty Prolonged Risk Detection with expanded protection for Amazon EKS clusters supplies complete safety monitoring throughout your Kubernetes atmosphere. You need to use this functionality to detect refined multistage assaults by correlating occasions throughout completely different knowledge sources, figuring out assault sequences that conventional monitoring may miss.
To begin utilizing this expanded protection, allow EKS Safety in your GuardDuty settings and take into account including Runtime Monitoring for enhanced detection capabilities.
