Organizations face significant challenges in detecting threats in AWS CloudTrail logs due to the nature of Cloud API transactions, which often lack conventional network or host-based evidence and can be indistinguishable from benign activities. The blog post by Craig Chamberlain explores the limitations of traditional search-based detection rules and highlights the use of machine learning techniques, specifically Elastic's anomaly detection, to identify unusual activities in cloud environments. Through case studies, the post illustrates how attackers have exploited cloud vulnerabilities, such as exfiltration via snapshots and multistage lateral movement, which conventional methods might miss. It emphasizes the effectiveness of combining machine learning-based anomaly detection with traditional search rules to enhance threat detection. Elastic's tools are designed to assist security teams in monitoring cloud API logs, identifying rare and suspicious activities, and efficiently managing alerts.
