TL;DR: A Japanese Tech giant, Fujitsu’s Dual-Loop Security Scheme. According to their website, the Dual-Loop scheme is a company-wide risk management mechanism designed to bridge the gap between top-down leadership and bottom-up operations, treating security as a core business issue rather than just a technical one.The Two Loops:• The Outer Loop (Top-Down Governance): Focuses on senior management involvement and the CISO (Chief Information Security Officer) organization. It uses digital dashboards, like the Risk Monitor, to visualize risks for leadership, allowing them to make informed, quantitative decisions. Its primary goal is to empower the CISO and resolve "competing demands," such as the conflict between business efficiency and security rigor.• The Inner Loop (Bottom-Up Autonomy): Focuses on field organizations managing risks in their daily operations. Departments conduct self-driven assessments and implement responses based on visualized data without waiting for top-down instructions. It encourages department heads to take an active leadership role in security rather than delegating it to staff.Key Enablers:• Assigned Roles: Each department has a System Security Manager, an Information Manager, and a PSIRT Manager to ensure local accountability.• Zero Trust & Resilience: The scheme supports a shift toward a "Zero Trust" model, where all entities must be authenticated, and an "attack-resilient" posture that identifies vulnerabilities from an attacker’s perspective.• Automated Remediation: Centralized IT asset management matches data against global vulnerability databases to trigger automated fixes within the "Inner Loop".The "Debate" (Potential Friction Points): Based on the sources, a debate would likely focus on "Competing Demands." Field organizations often face pressure to increase efficiency and reduce costs, which can conflict with the rigorous security implementation required by the CISO. Furthermore, there is a challenge in closing "accountability gaps" to ensure department heads do not leave security solely to their specialized staff.--------------------------------------------------------------------------------Analogy for Understanding: Fujitsu’s dual-loop scheme is like a modern high-performance racing team. The Outer Loop is the pit wall (senior management), using digital sensors to see the whole track and make strategic decisions about safety and speed. The Inner Loop represents the driver and mechanics (field organizations), who have the autonomy to make split-second adjustments based on the immediate conditions they feel on the track. Because both loops share the same data in real-time, they work as a single unit to ensure the car reaches the finish line safely.
