Tools Alone Won't Suffice: Building Systemic Kubernetes Security Across Hundreds of Clusters at Alfa-Bank
Alexander, lead of the K8S and cloud security department at Alfa-Bank, explains how the bank moved from fragmented tools and ad-hoc practices to a comprehensive process-driven security function covering more than 500 Kubernetes clusters. The approach centers on a threat lifecycle model that includes threat modeling, requirements definition, project expertise, auditing, risk assessment, platform operations, and SOC integration. A RACI matrix formalizes responsibilities across security, DevOps, AppSec Business Partners, and IT teams to ensure consistent execution at scale. Four specialized roles—an architect, analyst-engineer, auditor, and platform DevOps engineer—handle the workload that no single individual could manage. The bank emphasizes that commercial scanners and policies deliver value only when embedded in repeatable processes tied to a living threat model and clear accountability.
