What is Amazon GuardDuty?

Amazon GuardDuty is a security monitoring service that analyzes and processes Foundational data sources, such as Amazon CloudTrail management events, Amazon CloudTrail event logs, VPC flow logs (from Amazon EC2 instances), and DNS logs. It also processes Features such as Kubernetes audit logs, RDS login activity, S3 logs, EBS volumes, Runtime monitoring, and Lambda network activity logs. It uses threat intelligence feeds, such as lists of malicious IP addresses and domains, and machine learning to identify unexpected, potentially unauthorized, and malicious activity within your Amazon environment. This can include issues like escalation of privileges, use of exposed credentials, or communication with malicious IP addresses, domains, presence of malware on your Amazon EC2 instances and container workloads, or discovery of unusual patterns of login events on your database. For example, GuardDuty can detect compromised EC2 instances and container workloads serving malware, or mining bitcoin. It also monitors Amazon account access behavior for signs of compromise, such as unauthorized infrastructure deployments, like instances deployed in a Region that hasn't been used before, or unusual API calls like a password policy change to reduce password strength.

GuardDuty informs you of the status of your Amazon environment by producing security findings that you can view in the GuardDuty console or through Amazon EventBridge. GuardDuty also provides support for you to export your findings to an Amazon Simple Storage Service (S3) bucket, and integrate with other services such as Amazon Security Hub and Detective.
