1.2.7 Performing queries to validate security events for example, by using Amazon Athena - In this episode, we explore how to use Amazon Athena for validating security events, a key skill for the AWS Certified Security Specialty exam. Athena is a serverless, SQL-based query service that analyzes massive logs in Amazon S3, such as CloudTrail, VPC Flow Logs, and S3 access logs, helping uncover real threats like unauthorized access or data exfiltration. We break down real-world queries, including tracing suspicious API activity and validating network anomalies, and highlight their importance in both the exam and actual security operations. The episode features a case study of a healthcare company responding to a credential compromise, showing step-by-step how Athena queries helped detect and contain the breach and ensure compliance. We also share best practices for optimizing Athenalike efficient data storage, schema management, and automating queries for continuous monitoringplus discuss its integration with other AWS tools such as Security Hub and QuickSight. Finally, listeners will learn what exam scenarios to expect and how mastering Athenas query skills can empower effective incident response in complex AWS environments.
