Right now, I’m glad 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 wrestle to detect subtle 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 totally different knowledge sources and time durations.
GuardDuty Prolonged Menace Detection introduces a brand new essential severity discovering kind, 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 establish subtle 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 software, obtains privileged service account tokens, after which makes use of these elevated privileges to entry delicate Kubernetes secrets and techniques or AWS assets.
This new functionality makes use of GuardDuty correlation algorithms to look at and establish sequences of actions that point out potential compromise. It evaluates findings throughout safety plans and different sign sources to establish frequent and rising assault patterns. For every assault sequence detected, GuardDuty gives complete particulars, together with doubtlessly impacted assets, timeline of occasions, actors concerned, and indicators used to detect the sequence. The findings additionally map noticed actions to MITRE ATT&CK® techniques and methods and remediation suggestions primarily based on AWS greatest practices, serving to safety groups perceive the character of the menace.
To allow Prolonged Menace Detection for EKS, you want a minimum of one in every of these options enabled: EKS Safety or Runtime Monitoring. For max detection protection, we suggest enabling each to reinforce detection capabilities. EKS Safety screens management airplane actions by way of audit logs, and Runtime Monitoring observes behaviors inside containers. Collectively, they create an entire 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, overview 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 further configuration. GuardDuty consumes these audit logs straight from the EKS management airplane by way of an unbiased 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 may view from the Abstract dashboard the assault sequences and significant findings particularly associated to Kubernetes cluster compromise. You may observe that GuardDuty identifies complicated assault patterns in Kubernetes environments, resembling credential compromise occasions and suspicious actions inside EKS clusters. The visible illustration of findings by severity, useful resource impression, and assault sorts provides you a holistic view of your Amazon EKS safety posture. This implies you may prioritize essentially the most essential threats to your containerized workloads.
The Discovering particulars web page gives visibility into complicated assault sequences concentrating on EKS clusters, serving to you perceive the total scope of potential compromises. GuardDuty correlates indicators right into a timeline, mapping noticed behaviors to MITRE ATT&CK® techniques and methods resembling account manipulation, useful resource hijacking, and privilege escalation. This granular stage of perception reveals precisely how attackers progress by way of your Amazon EKS setting. It identifies affected assets like EKS workloads and repair accounts. The detailed breakdown of indicators, actors, and endpoints gives 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 may 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 belongings affected throughout an assault sequence. This unified useful resource checklist gives 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 resembling useful resource sorts, identifiers, creation dates, and namespace data, you may quickly assess which elements of your containerized infrastructure require rapid consideration. This targeted method eliminates guesswork throughout incident response, so you may prioritize remediation efforts on essentially the most essential affected assets and decrease the potential blast radius of Amazon EKS focused assaults.
Now accessible
Amazon GuardDuty Prolonged Menace Detection with expanded protection for Amazon EKS clusters gives complete safety monitoring throughout your Kubernetes setting. You need to use this functionality to detect subtle multistage assaults by correlating occasions throughout totally different knowledge sources, figuring out assault sequences that conventional monitoring would possibly miss.
To begin utilizing this expanded protection, allow EKS Safety in your GuardDuty settings and think about including Runtime Monitoring for enhanced detection capabilities.
