🧱 CISSP Domain 1 — Security and Risk Management
(SunExplains Elite Framework v3 + 3-Layer Pyramid Depth)
1️⃣ Understand, Adhere to and Promote Professional Ethics
| Technical Concept | Technical Definition | Purpose / Big Picture | Example 1 (Technical) | Example 2 (House Analogy) |
|---|---|---|---|---|
| ISC² Code of Professional Ethics | Four canons guiding CISSP conduct – protect society, act honorably, provide diligent service, advance the profession. | Builds global trust in security professionals. | Refusing to bypass audit logs even under pressure. | Architect refuses to hide cracks in a wall report. |
| Organizational Code of Ethics | Company-specific moral principles aligned to law + culture. | Reinforces ethical decision-making inside governance. | Following client-data privacy policy. | Family rules set to maintain harmony. |
🧠 Flow: Principles → Behavior → Trust
🔺 3-Layer Pyramid:
- Why: Ethics = trust currency of security.
- How: Managers model behavior → culture replicates it.
- Differentiate: ISC² (global professional) vs Org ethics (local policy).
