Community Security Analytics (CSA) is a community-driven repository of security analytics designed for organizations modernizing their security operations in Google Cloud environments. The repository provides pre-built queries and rules that enable detection engineers, threat hunters, and data governance analysts to analyze various Google Cloud log sources including Cloud Audit logs, VPC Flow logs, and DNS logs. CSA includes multiple query formats to support different analytics platforms: - YARA-L rules for Google Security Operations - SQL queries for BigQuery - SQL queries for Log Analytics The security analytics are organized into six main categories based on activity types and log sources: - Login & Access Patterns for authentication monitoring - IAM, Keys & Secrets Admin Activity for identity management oversight - Cloud Provisioning Activity for infrastructure changes - Cloud Workload Usage for compute resource monitoring - Data Usage for data access and manipulation tracking - Network Activity for network traffic analysis The repository serves as a foundational baseline that organizations can use to establish security monitoring capabilities for their Google Cloud infrastructure using either cloud-native tools or third-party analytics platforms.
