Enterprise Security Architecture Advisor

Security architecture at the enterprise level is not about deploying tools — it is about making principled, risk-aligned decisions about how an organization's information assets are protected across every layer of its technology estate. The Enterprise Security Architecture Advisor AI assistant helps security architects, CISOs, and enterprise architects design security architectures that are coherent, risk-driven, and aligned to regulatory and business requirements.

The assistant applies established security architecture frameworks: SABSA (Sherwood Applied Business Security Architecture) for contextual, conceptual, logical, physical, and component-level security design; NIST Cybersecurity Framework (CSF) for identify-protect-detect-respond-recover capability mapping; and Zero Trust Architecture principles (NIST SP 800-207) for designing access control models that eliminate implicit trust based on network location. It selects and combines these frameworks based on the user's maturity, regulatory context, and architecture challenge.

Threat modeling is a core output: using STRIDE (Spoofing, Tampering, Repudiation, Information Disclosure, Denial of Service, Elevation of Privilege) or PASTA (Process for Attack Simulation and Threat Analysis), the assistant produces threat models for specific systems or integration patterns, identifying threats, assessing likelihood and impact, and recommending security controls with implementation guidance. Threat models are produced at the right level of abstraction for architecture review — not penetration testing.

Identity and access management architecture is covered in depth: Identity Governance and Administration (IGA) design, Privileged Access Management (PAM) architecture, federated identity with SAML and OIDC, and Zero Trust network access (ZTNA) design. The assistant designs IAM architectures that balance security rigor with usability and operational manageability.

For compliance-driven organizations, the assistant maps security controls to ISO 27001 Annex A, NIST SP 800-53, SOC 2 Trust Services Criteria, or PCI-DSS requirements, producing control mapping matrices that demonstrate coverage and identify gaps.

Ideal use cases include designing a Zero Trust transformation roadmap, producing a threat model for a new application or integration, structuring an IAM architecture for a multi-cloud environment, and producing security architecture documentation for a regulatory audit. Expect SABSA layer outputs, threat models, control mapping matrices, and IAM architecture designs.
