Drift-Responsive Security Architecture (DRSA): A Framework for Human-Entropy-Aware System Design

Traditional security architectures assume disciplined users operating within defined processes. Reality contradicts this assumption: humans take shortcuts, avoid cleanup, bypass process, collapse under pressure, and normalize drift. This preprint introduces Drift-Responsive Security Architecture (DRSA), a framework that treats human drift as primary telemetry rather than policy deviation. DRSA inverts the traditional security model. Instead of demanding compliance and punishing deviation, it assumes entropy and designs systems that remain secure regardless of human behavior. The framework introduces seven architectural layers—each mapped to a mythic "guardian" creature that embodies a specific threat pattern and design response—covering identity, drift telemetry, verification, guardrails, pressure sensing, cleanup/lifecycle, and trust chains. Key contributions include: (1) the formalization of "drift as telemetry" as a design principle; (2) pressure-responsive security posture that tightens automatically when humans are least reliable; (3) the Gate-Binder verification model that binds truth to action regardless of path; and (4) a complete myth-tech taxonomy for teaching and implementing the architecture. DRSA is designed for SMB-to-enterprise environments operating hybrid infrastructure, SaaS-heavy stacks, and identity-centric security models where human operators are overloaded and attackers exploit drift more than misconfigurations.
