AWS CloudTrail is a service that logs every API call made to an AWS account, capturing details such as user identity, request parameters, and the source of the calls, which are stored in S3 buckets for further analysis. Integrating CloudTrail with the ELK Stack, Logz.io provides a solution that allows users to visualize and monitor their IT environments in real-time through tools like Logstash and Kibana. This integration helps organizations track access patterns, detect unusual activities, and set alerts for specific security events, enhancing the ability to protect sensitive data. The process involves designing an architecture that reads CloudTrail logs and pushes them into the ELK Stack for visualization and alerting. The integration, which takes less than five minutes to set up, enables users to gain insights into who accesses their environment, when, and from where, with specific use cases including geo-access control and root user access alerts.
