SECURITY

SECURITY = SECURITY_STANDARD × CANONIC = Structure(security) × (C1, C2, Temporal, Relational, C5) = owned security vertical

SECURITY = C1 ∩ C2 ∩ Temporal ∩ Relational ∩ C5 ∩ C6 = ENTERPRISE (#63)

Security always requires full Enterprise because:

• C1: Security policies must be stated
• C2: Security controls must be proven
• Temporal: Continuous monitoring, incident timelines
• Relational: System boundaries, trust zones
• C5: Security teams enforce
• C6: Control frameworks (NIST, ISO)

1. Defense in Depth

Security MUST be implemented in multiple layers. No single control failure should compromise the system.

Example: Protecting a database requires: network segmentation, firewall rules, authentication, authorization, encryption at rest, encryption in transit, audit logging, and backup. Failure of any one layer does not expose data.

2. Least Privilege

Access MUST be limited to the minimum necessary for the function.

Example: A developer needs read access to production logs for debugging. They MUST NOT have write access to production data, admin access to infrastructure, or access to unrelated systems.

3. Continuous Monitoring

Security posture MUST be continuously monitored and anomalies detected.

Example: A Security Information and Event Management (SIEM) system collects logs from all systems, correlates events, and alerts on suspicious patterns such as failed login attempts, unusual data access, or configuration changes.

4. Incident Response

Security incidents MUST have defined response procedures with clear ownership.

Example: When a potential breach is detected: (1) Contain the threat, (2) Preserve evidence, (3) Notify stakeholders, (4) Investigate root cause, (5) Remediate, (6) Document lessons learned. Each step has assigned roles and time requirements.

5. Risk-Based Prioritization

Security investments MUST be prioritized based on risk (likelihood × impact).

Example: A critical vulnerability in an internet-facing system with sensitive data (high likelihood, high impact) takes priority over a moderate vulnerability in an internal system with no sensitive data (low likelihood, low impact).

`` DECLARE(ISO27001) = ISO_27001 × CANONIC

Where: ISO 27001 provides Structure: - Annex A controls (93 controls in 4 themes) - Statement of Applicability - Risk assessment methodology - ISMS documentation

CANONIC provides Governance: - C1: Security policy as CANON - C2: Control evidence in COVERAGE - Temporal: Audit cycles, review periods - Relational: Scope boundaries - C5: Management review, enforcement

Result: ISO27001 = ENTERPRISE (#63)

Certification Lifecycle: Scope — Boundary defined Risk — Threats assessed Controls — Mitigations implemented Audit — Stage 1 + Stage 2 Certified — Certificate issued Maintain — Surveillance audits ``

`` DECLARE(ZeroTrust) = NIST_800-207 × CANONIC

Where: NIST 800-207 provides Structure: - Never trust, always verify - Assume breach - Verify explicitly - Use least privilege access

CANONIC provides Governance: - C1: Zero trust principles - C2: Verification logs - Temporal: Session validity, token expiry - Relational: Microsegmentation boundaries - C5: Policy enforcement points

Result: ZeroTrust = ENTERPRISE (#63)

Access Request Flow: Request — Subject requests access Verify — Identity validated Context — Time, location, device checked Authorize — Policy evaluated Grant — Access with constraints Monitor — Continuous validation ``

To create a CANONIC security vertical:

Select security framework (ISO 27001, NIST, CIS) Create scope with CANON.md inheriting /SECURITY/ Define security policies as axioms Document control evidence in COVERAGE.md Establish monitoring (continuous temporal) Define boundaries (relational scope) Implement enforcement (operational controls) Map to framework (structural conformance)

Result: Owned security vertical with auditable compliance.
