At this time, 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 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 would possibly detect particular person suspicious occasions, however usually miss the broader assault sample that spans throughout these completely different knowledge sources and time intervals.
GuardDuty Prolonged Menace Detection introduces a brand new vital severity discovering sort, 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 assets.
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 frequent and rising assault patterns. For every assault sequence detected, GuardDuty supplies complete particulars, together with probably 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 strategies and remediation suggestions based mostly on AWS finest practices, serving to safety groups perceive the character of the menace.
To allow Prolonged Menace Detection for EKS, you want not less than considered one of these options enabled: EKS Safety or Runtime Monitoring. For optimum 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 advanced 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 wish to allow EKS Safety. Within the navigation pane, select Eks safety. On the Eks safety web page, evaluate 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 aircraft by way 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 spanking new accounts becoming a member of the group.
To allow Runtime Monitoringselect Runtime Monitoring within the navigation pane. Below the Configuration tab, select Allow to allow Runtime Monitoring to your account.
Now, you possibly can view from the Abstract dashboard the assault sequences and significant findings particularly associated to Kubernetes cluster compromise. You possibly can observe that GuardDuty identifies advanced 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 affect, and assault sorts provides you a holistic view of your Amazon EKS safety posture. This implies you possibly can prioritize essentially the most vital threats to your containerized workloads.
The Discovering particulars web page supplies visibility into advanced assault sequences focusing 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 strategies 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 assets like EKS workloads and repair accounts. The detailed breakdown of indicators, actors, and endpoints supplies you with actionable context to know 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 exhibits context in regards to the particular belongings 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 consists of detailed attributes equivalent to useful resource sorts, identifiers, creation dates, and namespace info, you possibly can quickly assess which parts of your containerized infrastructure require quick consideration. This targeted method eliminates guesswork throughout incident response, so you possibly can prioritize remediation efforts on essentially the most vital affected assets and reduce the potential blast radius of Amazon EKS focused assaults.
Now out there
Amazon GuardDuty Prolonged Menace Detection with expanded protection for Amazon EKS clusters supplies complete safety monitoring throughout your Kubernetes atmosphere. You should use 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 contemplate including Runtime Monitoring for enhanced detection capabilities.
