GuardDuty will continually alert users regarding their AWS environment status and will send the security discoveries to the GuardDuty dashboard or Amazon CloudWatch events for users to view.
Users can access GuardDuty via:
-
AWS SDKs: Amazon provides users with several software development kits (SDKs) that are made up of libraries and sample code of numerous popular programming languages and platforms, such as Android, iOS, Java, .Net, Python, and Ruby. The SDKs make it easier to develop programmatic access to GuardDuty.
-
GuardDuty HTTPS API: This allows users to issue HTTPS requests directly to the service.
-
GuardDuty Console: This is a browser-based intuitive dashboard interface where users can access and use GuardDuty.
Amazon Elastic Kubernetes Service (Amazon EKS)
Kubernetes protection is an optional add-on in Amazon GuardDuty. This tool is able to discover malicious behavior and possible destabilization of an organization's Kubernetes clusters inside of Amazon Elastic Kubernetes Service (Amazon EKS).
When Amazon EKS is activated, GuardDuty will actively use various data sources to discover potential risks against Kubernetes API. When Kubernetes protection is enabled, GuardDuty uses optional data sources to detect threats against Kubernetes API.
Kubernetes audit logs are a Kubernetes feature that captures historical API activity from applications, the control plane, users, and endpoints. GuardDuty collates these logs from Amazon EKS to create Kubernetes discoveries for the organization's Amazon EKS assets; there is no need to store or turn on the logs.
As long as Kubernetes protection remains activated, GuardDuty will continuously dissect Kubernetes data sources from the Amazon EKS clusters to ensure no suspicious or anomalous behavior is taking place.
Amazon Simple Cloud Storage (S3) Protection
Amazon S3 allows Amazon GuardDuty to actively audit object-level API processes to discover possible security threats to data inside an organization's S3 buckets. GuardDuty continually audits risk to the organization’s S3 assets by carefully dissecting AWS CloudTrail management events and AWS CloudTrail S3 data events. These tools are continually auditing various CloudTrail management events for potential suspicious activities that affect S3 buckets, such as PutBucketReplication, DeleteBucket, ListBucket, and data events for S3 object-level API processes, such as PutObject, GetObject, ListObject, and DeleteObject.
Reviews from Real Users
“The most valuable features are the single system for data collection and the alert mechanisms. Prior to using GuardDuty, we had multiple systems to collect data and put it in a centralized location so we could look into it. Now we don't need to do that anymore as GuardDuty does it for us.” - Arunkumar A., Information Security Manager at Tata Consultancy Services
