Phase 5: Security Architecture Design
Status: Pending Research & Documentation
Dependencies: Phase 4 (Technical Architecture) must be complete
Next Phase: Phase 6 (Business Model)
Phase Overview
This phase focuses on designing comprehensive security architecture and framework based on the technical architecture established in Phase 4. Security requirements will inform business model costs and compliance planning in subsequent phases.
Research Scope
WebSearch Queries: 8 comprehensive queries covering security architecture, threat modeling, and compliance planning
Documentation Output: 4 comprehensive documents (16,000+ total words)
Research Focus: Industry security standards, threat landscapes, compliance frameworks
Documents to Research & Create
5.1 Security Architecture Design (security-architecture-design.md)
Target: 4,000+ words
Focus: Security architecture patterns based on competitor research, authentication/authorization design, infrastructure security requirements
5.2 Threat Modeling Analysis (security-threat-modeling.md)
Target: 4,000+ words
Focus: STRIDE/PASTA methodology, attack surface analysis, risk assessment, threat actor profiling
5.3 Security Requirements Specification (security-requirements-specification.md)
Target: 4,000+ words
Focus: Functional/non-functional security requirements, authentication, data protection, integration security
5.4 Compliance Planning Framework (security-compliance-planning.md)
Target: 4,000+ words
Focus: Regulatory landscape mapping, compliance framework selection, audit preparation, documentation requirements
Key Research Areas
- Security Architecture Patterns: Industry-standard security designs from competitor analysis
- Threat Landscape: Current security threats specific to the industry and technology stack
- Compliance Requirements: GDPR, SOC 2, ISO 27001, and industry-specific regulations
- Implementation Strategy: Security controls, monitoring, and incident response planning
Success Criteria
- All 8 WebSearch queries executed with comprehensive citations
- 4 documents created meeting word count requirements
- Security framework addresses all identified threats from research
- Compliance strategy meets regulatory requirements discovered through research
- Security design supports business objectives and technical architecture
Integration Points
Builds On: Phase 4 technical architecture, system design, and infrastructure decisions
Informs: Phase 6 business model (security costs), Phase 20 security compliance implementation
Dependencies: Technical architecture must be validated before security design can begin
This phase ensures security is built into the foundation rather than retrofitted later, following industry best practices and regulatory requirements discovered through comprehensive market research.
