Security › Module 6 › Lesson 2
Business Traceability
Business context literacy — business goal, risk appetite stub, stakeholder map, regulatory driver, value chain note — context rows on YOUR `$ARCH_LAB` LAB-ARCH-001.
Visual · t41_business_context
Business context = named stakeholder rows. $ARCH_LAB LAB-ARCH-001. Original Cyberlium.
Opening
Security architecture starts with business context — name goal and stakeholder rows on YOUR lab org before mapping stranger org systems without authorization.
Business context literacy names: business goal row category, risk appetite stub category, stakeholder map category, regulatory driver category, and value chain note category. Analyst documents business context sheet on `$ARCH_LAB` LAB-ARCH-001 — five context rows linking Module 6-1 SABSA contextual layer — without surveying stranger org business units, without claiming context equals live employer strategy without authorization, without fabricating regulatory drivers for fraud. Cyberlium teaches context vocabulary on YOUR notes — educational only. Refused: stranger org business theft, unauthorized employer strategy claims, fake compliance narratives. Lab row: business context sheet (five rows, stakeholder stub, LAB-ARCH-001 label).
1. Named context rows
Business goal, risk appetite, stakeholders, regulatory driver, value chain — five literacy anchors.
Each row cites YOUR lab fictional org — not stranger org executive summaries.

# API Gateway Pattern — LAB-ARCH-001 (defensive)
## Responsibilities
- Terminate TLS; validate OAuth2/OIDC tokens
- Route to internal services; strip internal headers
- Rate limiting + WAF rules at edge (literacy)
- Centralized request logging (no PAN/PII in access logs)
## Anti-patterns to avoid in design review
- Gateway bypass routes for "convenience"
- Shared service account for all backends
- Trusting internal network without service auth

2. Contextual layer link
Business context feeds SABSA contextual layer from Module 6-1 — same LAB-ARCH-001 thread.
Risk appetite stub documented honestly — not zero-risk fiction or inflated drama.
3. Refused
No stranger org business mapping; no unauthorized employer strategy claims; no fake regulatory narratives.
Context literacy supports honest architecture — not compliance theater.
4. What you ship: business context sheet
Five context rows + stakeholder stub + LAB-ARCH-001 label + NEVER stranger org mapping line.
5. What you record before the next lesson
Business context sheet path.
6. Wrong vs right: offensive playbooks vs YOUR threat models
Worked failure — same MSF word, opposite target. Right never needs a café Wi-Fi or classmate laptop.
Wrong
Survey stranger org public filings and map as `$ARCH_LAB` business context without authorization.
Right
Business context sheet from `$ARCH_LAB` LAB-ARCH-001. Next: Attribute Profiles.
Mission: business context sheet
1) Name five business context literacy rows. 2) Link to Module 6-1 contextual layer. 3) Stakeholder stub labeled LAB-ARCH-001. 4) Write NEVER stranger org business mapping line.
