guardduty

Description

Amazon GuardDuty is a continuous security monitoring service that analyzes and processes the following data sources: VPC flow logs, Amazon Web Services CloudTrail management event logs, CloudTrail S3 data event logs, EKS audit logs, and DNS logs. It uses threat intelligence feeds (such as lists of malicious IPs and domains) and machine learning to identify unexpected, potentially unauthorized, and malicious activity within your Amazon Web Services environment. This can include issues like escalations of privileges, uses of exposed credentials, or communication with malicious IPs, URLs, or domains. For example, GuardDuty can detect compromised EC2 instances that serve malware or mine bitcoin.

GuardDuty also monitors Amazon Web Services account access behavior for signs of compromise. Some examples of this are unauthorized infrastructure deployments such as EC2 instances deployed in a Region that has never been used, or unusual API calls like a password policy change to reduce password strength.

GuardDuty informs you of the status of your Amazon Web Services environment by producing security findings that you can view in the GuardDuty console or through Amazon CloudWatch events. For more information, see the * Amazon GuardDuty User Guide * .
