As we speak, I’m blissful to announce Amazon GuardDuty Prolonged Menace 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 Menace Detection: AI/ML assault sequence identification for enhanced cloud safety.
Safety groups managing Kubernetes workloads typically 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 would possibly 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 Menace Detection introduces a brand new essential severity discovering sort, which mechanically 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 determine refined assault patterns that may in any other case go unnoticed. For instance, GuardDuty can now detect assault sequences by which a risk 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 watch 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 doubtlessly 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 strategies and remediation suggestions based mostly on AWS finest practices, serving to safety groups perceive the character of the risk.
To allow Prolonged Menace Detection for EKS, you want a minimum of considered one of these options enabled: EKS Safety or Runtime Monitoring. For optimum detection protection, we suggest enabling each to boost detection capabilities. EKS Safety screens management aircraft actions via 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 Menace 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 save lots of 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 instantly from the EKS management aircraft via 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. Underneath 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’ll be able to observe that GuardDuty identifies complicated assault patterns in Kubernetes environments, corresponding to credential compromise occasions and suspicious actions inside EKS clusters. The visible illustration of findings by severity, useful resource affect, and assault varieties offers you a holistic view of your Amazon EKS safety posture. This implies you possibly can prioritize probably the most essential threats to your containerized workloads.
The Discovering particulars web page supplies visibility into complicated assault sequences concentrating 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 strategies corresponding to account manipulation, useful resource hijacking, and privilege escalation. This granular stage of perception reveals precisely how attackers progress via 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 grasp assault patterns, decide affect, and prioritize remediation efforts. By consolidating these safety insights right into a cohesive view, you possibly can rapidly assess the severity of Amazon EKS safety incidents, cut back investigation time, and implement focused countermeasures to guard your containerized functions.
The Assets part of the Discovering particulars web page reveals context concerning the particular belongings affected throughout an assault sequence. This unified useful resource checklist 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 contains detailed attributes corresponding to useful resource varieties, identifiers, creation dates, and namespace data, you possibly can quickly assess which elements of your containerized infrastructure require rapid consideration. This centered method eliminates guesswork throughout incident response, so you possibly can prioritize remediation efforts on probably the most essential affected sources and reduce the potential blast radius of Amazon EKS focused assaults.
Now obtainable
Amazon GuardDuty Prolonged Menace 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 would possibly miss.
To start out utilizing this expanded protection, allow EKS Safety in your GuardDuty settings and think about including Runtime Monitoring for enhanced detection capabilities.
