Quick Reference: Trust Services Criteria

| Category | Code | Required? | Criteria Series | |---|---|---|---| | Security (Common Criteria) | CC | **Always required** | CC1–CC9 | | Availability | A | Optional | A1 | | Confidentiality | C | Optional | C1 | | Processing Integrity | PI | Optional | PI1 | | Privacy | P | Optional | P1–P8 |

**CC1–CC9 breakdown:**

• CC1 Control Environment ("tone at top" — governance, integrity, oversight)
• CC2 Communication and Information
• CC3 Risk Assessment
• CC4 Monitoring Controls
• CC5 Control Activities
• CC6 Logical & Physical Access Controls
• CC7 System Operations (monitoring, incident response, DR)
• CC8 Change Management
• CC9 Risk Mitigation (vendor/third-party risk)

How to Help Users — Task Router

Identify the user's need and follow the relevant section below:

| What they ask for | Where to go | |---|---| | Gap analysis / readiness check | → [Gap Analysis](#gap-analysis--readiness-assessment) | | Write a policy or procedure | → [Policy Writing](#policy--procedure-writing) + `references/policies.md` | | Document a control | → [Control Documentation](#control-documentation) + `references/controls.md` | | Collect or prepare evidence | → [Audit Evidence](#audit-evidence-preparation) + `references/evidence.md` | | Vendor / third-party questionnaire | → [Vendor Risk](#vendor-risk-questionnaires) + `references/vendor.md` | | General question or explanation | → Answer directly from TSC knowledge |

Gap Analysis & Readiness Assessment

Step 1 — Scope

Before assessing, confirm: 1. **Report type:** Type 1 (point-in-time design only) or Type 2 (operating effectiveness over a period, typically 6–12 months)? 2. **TSC scope:** Which criteria will be included beyond the mandatory Security (CC)? 3. **System boundary:** What services, infrastructure, and data flows are in scope? 4. **Timeline:** When is the target audit date?

Step 2 — Self-Assessment Framework

For each in-scope criterion, assess:

• **Design:** Is a control designed and documented to meet this criterion?
• **Implementation:** Is the control actually in place and operating?
• **Evidence:** Can the organization prove it to an auditor?

Use this RAG status for each criterion:

• 🟢 **Met** — control is designed, implemented, and evidenced
• 🟡 **Partial** — control exists but has gaps (undocumented, inconsistently applied, missing evidence)
• 🔴 **Gap** — no control exists or is clearly insufficient

Step 3 — Common Gaps by Area

See `references/controls.md` for per-criterion gap patterns. The most frequently flagged gaps across all organizations:

1. **Policies not documented or not reviewed annually** (hits CC1, CC2, CC5) 2. **No formal risk assessment process** (CC3) 3. **Access reviews not performed** (CC6) 4. **Incident response plan not tested** (CC7) 5. **Change management not consistently followed** (CC8) 6. **No vendor risk program** (CC9) 7. **Availability SLAs not monitored or evidenced** (A1) 8. **Data classification not defined** (C1, P3) 9. **Privacy notice incomplete or missing** (P1)

Step 4 — Remediation Plan

For each 🔴 or 🟡 item, output a remediation plan entry:

Control Area: [TSC criterion, e.g., CC6.1]
Gap: [Description of what's missing]
Remediation: [Specific action required]
Owner: [Role responsible]
Target Date: [Realistic deadline]
Evidence Needed: [What will prove this is fixed]

Policy & Procedure Writing

Read `references/policies.md` for full templates and writing guidance.

Core Policy Set Required for SOC 2

| Policy | TSC Criteria Addressed | |---|---| | Information Security Policy | CC1, CC2, CC5 | | Access Control Policy | CC6 | | Incident Response Policy & Plan | CC7 | | Change Management Policy | CC8 | | Risk Assessment Policy | CC3 | | Vendor Management Policy | CC9 | | Business Continuity & DR Policy | A1, CC7 | | Data Classification Policy | C1, P3 | | Acceptable Use Policy | CC1, CC6 | | Privacy Policy / Notice | P1–P8 | | Encryption Policy | CC6, C1 | | Password / Authentication Policy | CC6 | | Vulnerability Management Policy | CC7 |

Policy Writing Principles

1. **Map explicitly to TSC** — each policy should state which criteria it supports 2. **Assign ownership** — every policy needs a named owner/role 3. **Include review cadence** — minimum annual review; major changes trigger ad-hoc review 4. **Be specific about scope** — state what systems, people, and data are covered 5. **Avoid vague language** — "as appropriate" or "where possible" weakens auditability 6. **Version control** — include version number, effective date, approval signature
