# Information Security Strategy Skill ## Purpose This skill provides strategic security planning guidance aligned with Hack23 AB's AI-augmented operating model and transparent ISMS implementation. It enables security architects and business leaders to align security controls with business impact classifications, demonstrate security excellence through public transparency, and leverage ISMS as competitive advantage for cybersecurity consulting services. ## When to Use This Skill Apply this skill when: - ✅ Developing security strategies for new products or services - ✅ Aligning security controls with business impact classifications - ✅ Designing defense-in-depth architectures - ✅ Evaluating risk-based security control selection - ✅ Planning AI-augmented security operations - ✅ Preparing security posture demonstrations for clients - ✅ Integrating security with Porter's Five Forces strategic analysis - ✅ Documenting security architecture decisions - ✅ Balancing transparency with confidentiality requirements Do NOT use for: - ❌ Tactical incident response (use incident-response skill) - ❌ Specific vulnerability remediation (use vulnerability-management skill) - ❌ Code-level security reviews (use secure-code-review skill) ## AI-First Security Operations Model ```mermaid graph TB CEO["👨‍💼 CEO/Founder<br/>Strategic Oversight"] subgraph AI_AGENTS["🤖 Specialist AI Agent Ecosystem"] SEC_ARCH["🔐 Security Architect Agent<br/>Architecture design & review"] DEV_SEC["💻 DevSecOps Agent<br/>CI/CD security integration"] TEST_SEC["🧪 Security Testing Agent<br/>SAST/DAST/Fuzzing"] DOC_SEC["📚 Documentation Agent<br/>Policy & procedure creation"] BIZ_SEC["💼 Business Agent<br/>Risk/value alignment"] MARKET_SEC["📢 Marketing Agent<br/>Security posture communication"] end CEO --> SEC_ARCH CEO --> DEV_SEC CEO --> TEST_SEC CEO --> DOC_SEC CEO --> BIZ_SEC CEO --> MARKET_SEC SEC_ARCH --> ARCH_OUT["📋 SECURITY_ARCHITECTURE.md<br/>THREAT_MODEL.md"] DEV_SEC --> CICD_OUT["⚙️ GitHub Actions Workflows<br/>Security Gates"] TEST_SEC --> TEST_OUT["🧪 CodeQL / OWASP ZAP<br/>Vulnerability Reports"] DOC_SEC --> DOC_OUT["📖 ISMS Policies<br/>Compliance Evidence"] BIZ_SEC --> BIZ_OUT["💰 Risk Register<br/>Business Impact Analysis"] MARKET_SEC --> MARKET_OUT["🏆 Security Badges<br/>Public Metrics"] ARCH_OUT --> EVIDENCE["🎖️ Public Evidence<br/>OpenSSF Scorecard<br/>CII Best Practices<br/>SLSA Level 3"] CICD_OUT --> EVIDENCE TEST_OUT --> EVIDENCE DOC_OUT --> EVIDENCE BIZ_OUT --> EVIDENCE MARKET_OUT --> EVIDENCE EVIDENCE --> CLIENTS["🤝 Client Demonstration<br/>Competitive Advantage"] style CEO fill:#1565C0,stroke:#0D47A1,stroke-width:3px,color:#fff style AI_AGENTS fill:#4CAF50,stroke:#2E7D32,stroke-width:2px style EVIDENCE fill:#FF9800,stroke:#F57C00,stroke-width:2px style CLIENTS fill:#9C27B0,stroke:#6A1B9A,stroke-width:2px ``` **Key Strategic Principles:** - **<1 FTE Operations:** AI agents handle 80%+ security tasks under CEO oversight - **Transparent by Default:** 70% of ISMS publicly visible (only credentials/pricing redacted) - **Evidence-Based:** All security claims backed by public badges and metrics - **Business Alignment:** ISMS is not separate from business—it IS the business model ## Product Security Architecture Decision Framework Use this decision tree when designing security controls for new products: ```mermaid flowchart TD START["🎯 New Product/Service"] --> CLASS{What is the<br/>Confidentiality<br/>Classification?} CLASS -->|Low| LOW_CONF["⚪ Low Confidentiality<br/>Public data only"] CLASS -->|Moderate| MOD_CONF["🟡 Moderate Confidentiality<br/>User accounts/data"] CLASS -->|High/Very High| HIGH_CONF["🔴 High/Very High<br/>Sensitive operations"] LOW_CONF --> AUTH_LOW{Does app process<br/>user-specific data?} AUTH_LOW -->|No| NO_AUTH["❌ No Authentication<br/>✅ TLS 1.3 Required<br/>Example: CIA CM, Black Trigram"] AUTH_LOW -->|Yes| BASIC_AUTH["🔐 Basic Authentication<br/>Username/Password"] MOD_CONF --> AUTH_MOD["🔐 Full Authentication Stack"] AUTH_MOD --> MFA["✅ MFA Required<br/>✅ RBAC<br/>✅ Session Management<br/>✅ Audit Logging"] HIGH_CONF --> AUTH_HIGH["🔐 Enhanced Security"] AUTH_HIGH --> ENHANCED["✅ MFA Mandatory<br/>✅ Fine-grained RBAC<br/>✅ Comprehensive Audit<br/>✅ Encryption at Rest<br/>Example: CIA Platform"] NO_AUTH --> RATIONALE_LOW["📋 Document Risk Acceptance<br/>Update Risk Register<br/>Reference Classification Framework"] BASIC_AUTH --> RATIONALE_MOD["📋 Document Control Selection<br/>Map to Classification Framework"] MFA --> RATIONALE_HIGH["📋 Full Security Architecture<br/>SECURITY_ARCHITECTURE.md"] ENHANCED --> RATIONALE_HIGH RATIONALE_LOW --> VERIFY["🧪 Verification Required"] RATIONALE_MOD --> VERIFY RATIONALE_HIGH --> VERIFY VERIFY --> V1["✅ SECURITY_ARCHITECTURE.md created"] VERIFY --> V2["✅ THREAT_MODEL.md completed"] VERIFY --> V3["✅ Risk Register updated"] VERIFY --> V4["✅ Classification badges in README"] style START fill:#1565C0,stroke:#0D47A1,stroke-width:2px,color:#fff style LOW_CONF fill:#9E9E9E,stroke:#616161,stroke-width:2px style MOD_CONF fill:#FF9800,stroke:#F57C00,stroke-width:2px style HIGH_CONF fill:#D32F2F,stroke:#B71C1C,stroke-width:3px,color:#fff style NO_AUTH fill:#4CAF50,stroke:#2E7D32,stroke-width:2px,color:#fff style ENHANCED fill:#B71C1C,stroke:#880E4F,stroke-width:3px,color:#fff style VERIFY fill:#7B1FA2,stroke:#4A148C,stroke-width:2px,color:#fff ``` ## Security Control Selection by Business Impact Map security controls to [Classification Framework](https://github.com/Hack23/ISMS-PUBLIC/blob/main/CLASSIFICATION.md) business impact levels: ### High Business Impact Products **CIA Platform** - Moderate Confidentiality, High Integrity, Moderate Availability **Required Controls:** ```yaml authentication: type: "Multi-factor with RBAC" implementation: "Spring Security + JWT + MFA" session: "Server-side with Redis" audit_logging: framework: "Javers + AWS CloudTrail" retention: "7 years (regulatory compliance)" monitoring: "Real-time with CloudWatch alarms" encryption: in_transit: "TLS 1.3 enforced" at_rest: "PostgreSQL encryption + AWS KMS" access_control: model: "Role-Based Access Control (RBAC)" segregation: "Admin/User/Anonymous roles" ``` **Architecture Documentation:** - [SECURITY_ARCHITECTURE.md](https://github.com/Hack23/cia/blob/master/SECURITY_ARCHITECTURE.md) - [THREAT_MODEL.md](https://github.com/Hack23/cia/blob/master/THREAT_MODEL.md) ### Low Business Impact Products **CIA Compliance Manager, Black Trigram** - Low Confidentiality, Moderate Integrity **Required Controls:** ```yaml authentication: type: "None (intentional risk acceptance)" rationale: "Public data only, no user-specific operations" risk_documentation: "Risk_Register.md entry with annual review" encryption: in_transit: "TLS 1.3 enforced via CDN" at_rest: "Not applicable (no backend database)" session_management: type: "Browser-only (localStorage/sessionStorage)" scope: "UI state persistence only" monitoring: application: "None (frontend-only, stateless)" infrastructure: "CDN access logs only" ``` **Risk Acceptance Documentation:** > The absence of authentication is an intentional architectural decision based on Low confidentiality classification. All data processed is public compliance framework information with no sensitive user data. This risk is documented in the Risk Register with periodic review triggers if feature requirements change. **Architecture Documentation:** - [CIA CM SECURITY_ARCHITECTURE.md](https://github.com/Hack23/cia-compliance-manager/blob/main/docs/architecture/SECURITY_ARCHITECTURE.md) -
