Security architecture has evolved into a strategic enterprise capability. Modern organizations require a principled, risk‑aligned, and methodologically rigorous approach that integrates seamlessly with enterprise architecture, governance, and digital transformation.
This resource collection provides practical, enterprise‑grade guidance for designing, governing, and operating security architecture across the modern technology landscape.
Security Architecture Resources
A Unified Model for Modern Security Architecture (White Paper)
A comprehensive model integrating TOGAF®, SABSA®, COBIT®, and The Open Group Axioms into a cohesive security architecture approach for 2026 and beyond. Includes layered models, governance alignment, and practical implementation guidance.
DevSecOps as the Execution Layer of Modern Security Architecture (White Paper)
The operational companion to the Unified Model — showing how DevSecOps automates governance, enforces architectural decisions, and delivers continuous assurance across multicloud, hybrid, and distributed environments. Provides a reference model aligned to all five layers of the Unified Security Architecture.
Security Architecture Reference Model
A structured, layered reference model aligning business drivers, architecture method, governance, design principles, and implementation patterns — providing a consistent foundation for enterprise security architecture.
Zero Trust Architecture Guide
A practical, architecture‑driven approach to designing and governing Zero Trust across identity, network, data, workloads, and cloud environments — aligned with enterprise strategy and risk posture.
Identity Fabric Architecture
A modern identity architecture model supporting distributed identity, adaptive access, trust decisions, and enterprise‑wide identity governance — essential for Zero Trust and cloud ecosystems.
API & Microservices Security Architecture
A structured approach to securing API ecosystems, service meshes, and distributed workloads — including patterns, controls, and governance models for modern digital platforms.
Cloud‑Native Security Architecture
Patterns and controls for securing cloud platforms, landing zones, workloads, and multi‑cloud environments — aligned with enterprise architecture and modern engineering practices.
AI/ML Security & Governance
A model for governing AI/ML systems, ensuring trustworthiness, risk alignment, compliance, and responsible use — integrated with enterprise architecture and security governance.
Security Governance & Assurance
A governance model integrating COBIT objectives, maturity models, decision rights, and performance measurement with security architecture — enabling accountability and continuous improvement.
Security Architecture Design Principles
A curated set of design principles grounded in The Open Group Axioms — supporting clarity, simplicity, reuse, resilience, and sustainable architectural decision‑making.
Security Architecture Value Chain
A conceptual model showing how business strategy flows into drivers, architecture, governance, implementation, and measurable business value — enabling security to function as a strategic capability.
