Amazon GuardDuty

How Amazon GuardDuty Works

Amazon GuardDuty works by collecting data from a variety of sources, including AWS CloudTrail, Amazon VPC Flow Logs, and Amazon S3 access logs. This data is analyzed using machine learning and anomaly detection algorithms to identify suspicious activity. GuardDuty also uses threat intelligence to identify known security threats and vulnerabilities.

When GuardDuty detects a potential threat, it generates a finding. Findings are categorized into different levels of severity, from low to high. You can view findings in the GuardDuty console or through the AWS Security Hub.

Using Amazon GuardDuty

To use Amazon GuardDuty, you must first create a detector. A detector is a resource that defines the scope of your GuardDuty deployment. You can create multiple detectors to monitor different AWS accounts or workloads.

Once you have created a detector, GuardDuty will begin collecting data and generating findings. You can view findings in the GuardDuty console or through the AWS Security Hub.

Pricing

Amazon GuardDuty is priced on a per-finding basis. The cost of each finding depends on the severity of the finding. You can find more information about GuardDuty pricing on the AWS website.
