Automated Incident Response Infrastructure in GCP

This post details the deployment of Google's GRR (GRR Rapid Response) framework for automated incident response and live forensics within Spotify's GCP infrastructure. It describes the architecture of GRR (Frontend, Worker, Admin UI) and the use of Terraform to deploy a scalable, secure instance. Key technical contributions include the use of Container-Optimized OS, GCP Load Balancers, Identity-Aware Proxy for authentication, and Google SQL for communication. The post highlights the ability to remotely pull process memory, perform signature searches with Yara, and integrate artifacts into the intrusion detection pipeline, significantly improving visibility and response capabilities for security incidents.
