In their own words
Amazon GuardDuty
Amazon GuardDuty monitors AWS accounts and workloads for malicious activity and generates security findings for response. It analyzes CloudTrail, VPC Flow, DNS, S3, Aurora login, AWS Backup, AI workload, and runtime activity. Detection combines AI, machine learning, anomaly detection, and AWS and third-party threat intelligence. Runtime Monitoring covers EKS, ECS workloads including those on Fargate, and EC2 instances. GuardDuty can scan EC2-attached EBS volumes after suspicious activity and detect potentially harmful uploads to S3 buckets. AI Protection addresses threats such as unusual model invocations, cost harvesting, and prompt injection attempts in Amazon Bedrock and SageMaker workloads. Findings can go to AWS Security Hub, EventBridge, Amazon Detective, or third-party solutions. Foundational protections require no additional security software or infrastructure to deploy and maintain. The service is pay as you go: charges depend on analyzed data and vary by source and AWS Region. New accounts can receive a 30-day trial in supported Regions, and some features are unavailable in some Regions.
