Amazon Detective Helps Kubernetes Workloads on Amazon EKS for Safety Investigations


In March 2020, we launched Amazon Detective, a totally managed service that makes it straightforward to investigate, examine, and shortly determine the basis reason behind potential safety points or suspicious actions.

Amazon Detective constantly extracts temporal occasions resembling login makes an attempt, API calls, and community site visitors from Amazon GuardDutyAWS CloudTrail, and Amazon Digital Non-public Cloud (Amazon VPC) Stream Logs right into a graph mannequin that summarizes the useful resource behaviors and interactions noticed throughout your complete AWS atmosphere. We’ve got added new options resembling AWS IAM Function session evaluation, enhanced IP deal with analytics, Splunk integration, Amazon S3 and DNS discovering varieties, and the assist of AWS Organizations.

Prospects are quickly shifting to containers to deploy Kubernetes workloads with Amazon Elastic Kubernetes Service (Amazon EKS). Its extremely programmatic nature permits 1000’s of particular person container deployments and hundreds of thousands of configuration adjustments to happen in seconds. To successfully safe EKS workloads, you will need to monitor container deployments and configurations which might be captured within the type of EKS audit logs and to correlate actions to consumer exercise and community site visitors taking place throughout AWS accounts.

As we speak we announce new capabilities in Amazon Detective to develop safety investigation protection for Kubernetes workloads working on Amazon EKS. If you allow this new characteristic, Amazon Detective routinely begins ingesting EKS audit logs to seize chronological API exercise from customers, purposes, and the management aircraft in Amazon EKS for clusters, pods, container photos, and Kubernetes topics (Kubernetes customers and repair accounts).

Detective routinely correlates consumer exercise utilizing CloudTrail, and community exercise utilizing Amazon VPC Stream logs, with out the necessity so that you can allow, retailer, or retain logs manually. The service gleans key safety data from these logs and retains them in a safety behavioral graph database that allows quick cross-referenced entry to 12 months of exercise. Detective supplies an information evaluation and visualization layer purpose-built to reply widespread safety questions backed by a behavioral graph database that means that you can shortly examine potential malicious conduct related along with your EKS workloads.

You’ll be able to quickly reply to safety points slightly than specializing in log administration, operational techniques, or ongoing safety tooling upkeep. Detective’s EKS capabilities include a free 30-day trial for all prospects that means that you can be sure that the capabilities meet your wants and to totally perceive the price for the service on an ongoing foundation.

You’ll be able to see current monitoring outcomes of your EKS clusters on the Abstract web page.

If you select one of many EKS clusters, you will notice the main points of containers working within the cluster, Kubernetes API actions, and community actions that occurred on this useful resource across the scope time.

Within the Overview tab, you additionally see particulars about all containers working within the cluster, together with their pod, picture and safety context.

Within the Kubernetes API exercise tab, you may get an summary of the total API actions involving the EKS cluster. You’ll be able to select a time vary to drill down primarily based on particular API strategies throughout the EKS cluster. When you choose a selected time, you possibly can see API topics, IP addresses, and the variety of API calls by the success, failure, unauthorized, or forbidden state.

It’s also possible to see particulars of newly noticed Kubernetes API calls  inside this cluster for the primary time and topics with elevated quantity that occurred contained in the cluster.

Enabling GuardDuty EKS Safety
In January 2022, Amazon GuardDuty expanded protection to EKS cluster exercise to determine malicious or suspicious conduct that represents potential threats to container workloads.

When the optionally available GuardDuty EKS Safety is enabled, GuardDuty will constantly monitor your EKS deployments and warn you to threats detected in your workloads. You’ll be able to view and examine these safety findings in Detective.

With Detective for EKS enabled, you possibly can shortly entry details about the sources concerned within the discovering, resembling their CloudTrail and Kubernetes API exercise, and netflow data. This will assist in investigation and enable you to decide root trigger, affect, and different associated sources which will even be compromised.

Now Out there
Now you can use Amazon Detective for EKS safety in all Areas the place Amazon Detective is on the market. This characteristic is priced primarily based on the quantity of audit logs processed and analyzed by Detective.

Detective supplies a free 30-day trial to all prospects that allow EKS protection, permitting prospects to make sure that Detective’s capabilities meet safety wants and to get an estimate of the service’s month-to-month price earlier than committing to paid utilization. To be taught extra, see the Detective pricing web page.

For technical documentation, go to the Amazon Detective Consumer Information. Please ship suggestions to AWS re:Put up for Amazon Detective or by means of your typical AWS assist contacts.

Be taught all the main points about Amazon Detective for EKS safety and get began at the moment.
