# Information Security Strategy Skill ## 🔴 AI FIRST Quality Principle > **Apply the AI FIRST principle: never accept first-pass quality. Minimum 2 iterations. Read all output, improve every section. No shortcuts.** ## Purpose Defines the information security strategy framework for Hack23 projects, integrating risk management with compliance requirements. ## Security Strategy Pillars 1. **Governance** — Policies, procedures, roles 2. **Risk Management** — Identify, assess, treat risks 3. **Compliance** — ISO 27001, NIST CSF, CIS Controls 4. **Operations** — Monitoring, incident response 5. **Assurance** — Audits, testing, continuous improvement ## Risk Management Process 1. **Context** — Scope, stakeholders, criteria 2. **Assessment** — Identify, analyze, evaluate risks 3. **Treatment** — Accept, mitigate, transfer, avoid 4. **Monitoring** — Continuous risk review 5. **Communication** — Stakeholder reporting ## Compliance Framework Integration | Framework | Focus | Key Controls | |-----------|-------|-------------| | ISO 27001:2022 | ISMS | 93 controls in 4 themes | | NIST CSF 2.0 | Cybersecurity | Govern, Identify, Protect, Detect, Respond, Recover | | CIS Controls v8.1 | Implementation | 18 control groups | | GDPR | Privacy | Data protection, rights | | NIS2 | Critical infra | Supply chain, incident reporting | ## Security Metrics - Mean Time to Detect (MTTD) - Mean Time to Respond (MTTR) - Vulnerability remediation SLA compliance - Security training completion rate - Audit finding closure rate ## Continuous Improvement - Regular policy reviews (annual minimum) - Lessons learned from incidents - Benchmark against industry standards - Security awareness program updates - Technology evolution tracking ## Related Hack23 ISMS Policies Strategy execution requires cross-policy alignment across the [ISMS-PUBLIC](https://github.com/Hack23/ISMS-PUBLIC) suite: ### Governance & Classification - [Information_Security_Policy.md](https://github.com/Hack23/ISMS-PUBLIC/blob/main/Information_Security_Policy.md) — **master policy**: scope, roles, risk management, continuous improvement (master strategy document) - [CLASSIFICATION.md](https://github.com/Hack23/ISMS-PUBLIC/blob/main/CLASSIFICATION.md) — CIA triad ratings + RTO/RPO drive control selection - [AI_Policy.md](https://github.com/Hack23/ISMS-PUBLIC/blob/main/AI_Policy.md) — AI governance, human-in-the-loop, agent-activity logging ### Operational - [Secure_Development_Policy.md](https://github.com/Hack23/ISMS-PUBLIC/blob/main/Secure_Development_Policy.md) — SDLC security - [Open_Source_Policy.md](https://github.com/Hack23/ISMS-PUBLIC/blob/main/Open_Source_Policy.md) — supply chain, SBOM, licence approvals - [Access_Control_Policy.md](https://github.com/Hack23/ISMS-PUBLIC/blob/main/Access_Control_Policy.md) · [Cryptography_Policy.md](https://github.com/Hack23/ISMS-PUBLIC/blob/main/Cryptography_Policy.md) · [Change_Management.md](https://github.com/Hack23/ISMS-PUBLIC/blob/main/Change_Management.md) - [Threat_Modeling.md](https://github.com/Hack23/ISMS-PUBLIC/blob/main/Threat_Modeling.md) · [Vulnerability_Management.md](https://github.com/Hack23/ISMS-PUBLIC/blob/main/Vulnerability_Management.md) - [Incident_Response_Plan.md](https://github.com/Hack23/ISMS-PUBLIC/blob/main/Incident_Response_Plan.md) · [Security_Metrics.md](https://github.com/Hack23/ISMS-PUBLIC/blob/main/Security_Metrics.md) ### Strategic Alignment Principle Every strategic initiative MUST map to: (a) one or more ISMS policies, (b) measurable KPI in `Security_Metrics.md`, (c) at least one compliance framework (ISO 27001 / NIST CSF 2.0 / CIS Controls v8.1 / GDPR / NIS2 / EU CRA), and (d) risk-treatment action in the risk register.
