Amazon GuardDuty introduces machine learning domain reputation model to expand threat detection and improve accuracy
Amazon GuardDuty introduces a new machine learning domain reputation model that can categorize previously unseen domains as highly likely to be malicious or benign based on their behavioral characteristics. GuardDuty uses this new capability to alert customers when an EC2 instance in their AWS environment is communicating with a domain identified as malicious and to improve the accuracy of existing domain based threat detections.

GuardDuty uses this new capability to alert customers when an EC2 instance in their AWS environment is communicating with a domain identified as malicious and to improve the accuracy of existing domain based threat detections.
The machine learning domain reputation model analyzes domain requests based on behavioral characteristics, such as popularity, history, and whether they are associated with known malicious or cryptocurrency-related domains and IPs. There are now four new domain reputation finding types in the continuously growing threat detection library that are on by default for all Amazon GuardDuty customers:
- Impact:EC2/MaliciousDomainRequest.Reputation
- Impact:EC2/AbusedDomainRequest.Reputation
- Impact:EC2/SuspiciousDomainRequest.Reputation
- Impact:EC2/BitcoinDomainRequest.Reputation
Available globally, Amazon GuardDuty continuously monitors for malicious or unauthorized behavior to help protect your AWS resources, including your AWS accounts, access keys, and EC2 instances. GuardDuty identifies unusual or unauthorized activity, like cryptocurrency mining, access to data stored in S3 from unusual locations, or infrastructure deployments in a region that has never been used. Powered by threat intelligence, machine learning, and anomaly detection techniques to detect threats, GuardDuty is continuously evolving to help you protect your AWS environment.
You can enable your 30-day free trial of Amazon GuardDuty with a single-click in the AWS Management console. To learn more, see Amazon GuardDuty Findings, and Amazon GuardDuty S3 Threat Protection. See the AWS Regions page for all the regions where GuardDuty is available.
