As we speak, I’m blissful 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 usually battle to detect refined multistage assaults that concentrate on containerized functions. 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 usually miss the broader assault sample that spans throughout these completely different knowledge sources and time durations.
GuardDuty Prolonged Risk Detection introduces a brand new vital severity discovering kind, which robotically correlates safety alerts throughout Amazon EKS audit logs, runtime behaviors of processes related to EKS clusters, malware execution in EKS clusters, and AWS API exercise to determine refined assault patterns which may in any other case go unnoticed. For instance, GuardDuty can now detect assault sequences wherein a menace actor exploits a container utility, 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 look at and determine sequences of actions that point out potential compromise. It evaluates findings throughout safety plans and different sign sources to determine 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® techniques and strategies and remediation suggestions primarily based on AWS finest practices, serving to safety groups perceive the character of the menace.
To allow Prolonged Risk Detection for EKS, you want at the very least one in every of these options enabled: EKS Safety or Runtime Monitoring. For optimum detection protection, we suggest enabling each to reinforce detection capabilities. EKS Safety screens management airplane actions by means of audit logs, and Runtime Monitoring observes behaviors inside containers. Collectively, they create a whole view of your EKS clusters, enabling GuardDuty to detect advanced 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 wish to allow EKS Safety. Within the navigation pane, select EKS Safety. On the EKS Safety web page, overview the present standing and select Allow. Choose Affirm 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 further configuration. GuardDuty consumes these audit logs instantly from the EKS management airplane by means of an impartial stream, which doesn’t have an effect on any current 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 new accounts becoming a member of the group.
To allow Runtime Monitoring, select Runtime Monitoring within the navigation pane. Below the Configuration tab, select Allow to allow Runtime Monitoring on your account.
Now, you’ll be able to view from the Abstract dashboard the assault sequences and important findings particularly associated to Kubernetes cluster compromise. You’ll be able to observe that GuardDuty identifies advanced assault patterns in Kubernetes environments, similar to credential compromise occasions and suspicious actions inside EKS clusters. The visible illustration of findings by severity, useful resource influence, and assault varieties provides you a holistic view of your Amazon EKS safety posture. This implies you’ll be able to prioritize essentially the most vital threats to your containerized workloads.
The Discovering particulars web page supplies visibility into advanced assault sequences concentrating on EKS clusters, serving to you perceive the total scope of potential compromises. GuardDuty correlates alerts right into a timeline, mapping noticed behaviors to MITRE ATT&CK® techniques and strategies similar to account manipulation, useful resource hijacking, and privilege escalation. This granular stage of perception reveals precisely how attackers progress by means of your Amazon EKS setting. It identifies affected sources like EKS workloads and repair accounts. The detailed breakdown of indicators, actors, and endpoints supplies you with actionable context to know assault patterns, decide influence, and prioritize remediation efforts. By consolidating these safety insights right into a cohesive view, you’ll be able to rapidly assess the severity of Amazon EKS safety incidents, cut back investigation time, and implement focused countermeasures to guard your containerized functions.
The Sources part of the Discovering particulars web page reveals context concerning the particular property affected throughout an assault sequence. This unified useful resource listing supplies you with visibility into the precise scope of the compromise—from the preliminary entry to the focused Kubernetes parts. As a result of GuardDuty contains detailed attributes similar to useful resource varieties, identifiers, creation dates, and namespace info, you’ll be able to quickly assess which parts of your containerized infrastructure require fast consideration. This targeted strategy eliminates guesswork throughout incident response, so you’ll be able to prioritize remediation efforts on essentially the most vital 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 setting. You should utilize 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 start out utilizing this expanded protection, allow EKS Safety in your GuardDuty settings and take into account including Runtime Monitoring for enhanced detection capabilities.
