What is AWS GuardDuty?

Amazon Guard Duty is a continuous cloud security monitoring service that consistently monitors and administers several data sources. These include AWS CloudTrail data events for EKS (Elastic Kubernetes Service) audit logs, VPC (Virtual Private Cloud) flow logs, DNS (Domain Name System) logs, S3 (Simple Cloud Storage), and AWS CloudTrail event logs.

Amazon GuardDuty intuitively uses threat intelligence data - such as lists of malicious domains and IP addresses - and ML (machine learning) to quickly discover suspicious and problematic activity in a user's AWS ecosystem. Activities may include concerns such as interactions with malicious IP addresses or domains, exposed credentials usage, or changes and/or escalation of privileges.

GuardDuty is able to easily determine problematic AWS EC2 (Elastic Compute Cloud) instances delivering malware or mining bitcoin. It is also able to trace AWS account access history for evidence of destabilization. such as suspicious API calls resulting in changing password policies to minimize password strength or anomalous infrastructure deployments in new or different never-used regions.

Featured AWS GuardDuty reviews

AWS Cloud Engineer at Standard Telephones and Cables

GuardDuty is limited to AWS environments. While incorporating Amazon Detective for detailed investigation can be useful, including more granular details in findings, such as specific user actions or historical comparisons, would be beneficial. Furthermore, managing global AWS environments requires setting up additional tools for viewing GuardDuty findings across multiple regions. A unified dashboard that aggregates findings across all regions without requiring manual aggregation could enhance convenience for users.

GuardDuty is extensive in terms of configuration and security compliance. It integrates with threat detection, offering end-to-end visibility. The best thing is that it notifies you immediately when something goes wrong, allowing quick response to threats. Our infrastructure is continuously monitored, safeguarding it against threats. Even internal threats are easy to identify. AWS monitors user behavior, which helps detect compromised credentials.

Because it's a threat detection service, they need to keep up with the various threat factors because new threat factors and attack factors come up all the time. Sometimes they may detect a certain behavior. But if that behavior morphs into something else, GuardDuty may not pick up on that specifically if something new comes up which hasn't been found or uncovered before. If Amazon doesn't update the service to reflect that or address that or factor that in, it may not detect the threat. The end user then is obviously at the mercy of whatever it flags. GuardDuty must ensure they cover everything, including the latest threats.

Learn more about AWS GuardDuty

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
