The AWS Excessive Security Scanning detection rule is designed to identify suspicious activity in Amazon Web Services (AWS) environments by monitoring for an abnormal volume of API calls across Describe, List, or Get operations. This analysis relies on AWS CloudTrail logs to aggregate data and flag user accounts exceeding 50 distinct events in a given timeframe. Such behavior can indicate potential reconnaissance actions taken by a threat actor who seeks to gain an understanding of the AWS infrastructure layout, which may signal a preparatory step prior to a malicious attack, opening avenues for unauthorized data access or exploitative strategies. The implemented search employs statistical functions to filter high-frequency API call patterns, while allowing for drilldown capabilities into specific user actions and associated risks.
