In practice, this means you can prove you information objectives-level controls on a defined cadence. ## Why it matters Every SOC 2 audit opinion is built control-by-control from the Trust Services Criteria. A missing or failing criterion produces an exception in the report, which buyers, partners and procurement teams read line-by-line during vendor reviews. ## What an auditor looks for A SOC 2 auditor (under AT-C §§ 105/205) tests both design and operating effectiveness over the audit window. For each criterion they expect a written control, a control owner, a population of events, and a sample tested against the population — including remediation tickets for exceptions. Within **Common Criteria (Security)**, the assessor will trace your implementation back to the catalogue reference (Criterion CC6.7) and look for objective evidence on the latest two assessment cycles. ## How to implement #### Physical Security **Inheritance.** For cloud-only operations, inherit physical controls from the provider's SOC 2 / ISO 27001 report and document the inheritance in the SoA. #### Policy Management **Docs.** Keep each policy in version-controlled Markdown alongside the code that implements it; ship a signed PDF snapshot at each annual review and link the SHA into the SoA. ### Operational checklist - **Information.** Document the trigger, the owner and the cadence. - **Internal.** Document the trigger, the owner and the cadence. - **External.** Document the trigger, the owner and the cadence. - **Risk.** Document the trigger, the owner and the cadence. - **Physical.** Document the trigger, the owner and the cadence. - **Scope:** objectives, controls, management. ## Evidence to collect - **Policy Document.** A signed and version-controlled policy / standard / procedure document. - **Infra Scan.** Continuous infrastructure-posture telemetry — AWS Config, Azure Policy compliance, GCP Organisation Policy, Wiz / Prisma findings. Signed policy or standard documents the safeguard. Focus: Transmission Controls (Original component: Logical and Physical Access Controls). ## Common pitfalls - Policies that no engineer has read; the version in Confluence drifts from the version that's actually being enforced. ## How it maps to other frameworks Computed from shared tags, control component and key-operation subjects — handy when you are reconciling controls across an audit. - [**ISO/IEC 27001:2022 A.7.3** — Securing offices, rooms and facilities](https://support.icompaas.com/compliance/iso-27001-2022/a-7-3-securing-offices-rooms-and-facilities) - [**HIPAA (45 CFR Part 164) 164.312(b)** — Audit Controls](https://support.icompaas.com/compliance/hipaa/164-312-b-audit-controls) - [**NIST SP 800-53 Rev. 5 CP-7** — Alternate Processing Site](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/cp-7-alternate-processing-site) - [**GDPR Article 1** — Subject-matter and objectives](https://support.icompaas.com/compliance/gdpr/article-1-subject-matter-and-objectives) - [**NIST SP 800-171 Rev. 3 3.13.15** — Session Authenticity](https://support.icompaas.com/compliance/nist-sp-800-171-rev-3/3-13-15-session-authenticity) ## Related controls in SOC 2 (2017 TSC) - [**Criterion CC5.2** — Technology Control Activities to Support Objectives](https://support.icompaas.com/compliance/soc-2-trust-services-criteria/cc5-2-technology-control-activities-to-support-objectives) - [**Criterion CC2.2** — Internal Communications](https://support.icompaas.com/compliance/soc-2-trust-services-criteria/cc2-2-internal-communications) - [**Criterion CC5.1** — Control Selection and Development](https://support.icompaas.com/compliance/soc-2-trust-services-criteria/cc5-1-control-selection-and-development) - [**Criterion PI1.4** — Output Controls](https://support.icompaas.com/compliance/soc-2-trust-services-criteria/pi1-4-output-controls) - [**Criterion PI1.5** — Storage Controls](https://support.icompaas.com/compliance/soc-2-trust-services-criteria/pi1-5-storage-controls) - [**Criterion CC2.3** — External Communication on Internal Control Matters](https://support.icompaas.com/compliance/soc-2-trust-services-criteria/cc2-3-external-communication-on-internal-control-matters) ## References - [AICPA / ASEC — SOC 2 (2017 TSC)](https://www.aicpa-cima.com/topic/audit-assurance/audit-and-assurance-greater-than-soc-2) - Catalogue identifier: `Criterion CC6.7` Topics: governance riskphysical securitypolicy management ## Related compliance guidance - [SOC 2 compliance: a practical implementation guide for cloud-native SaaS teams](https://support.icompaas.com/compliance/soc-2-trust-services-criteria): Start with the full SOC 2 implementation guide — scope, roadmap, evidence and how the assessment runs. - [ISO/IEC 27001:2022 compliance: a practical implementation guide](https://support.icompaas.com/compliance/iso-27001-2022): The certificate most non-US customers ask for instead of SOC 2; the controls overlap enough to run one matrix for both. - [HIPAA compliance for SaaS: a practical implementation guide](https://support.icompaas.com/compliance/hipaa): If health-tech customers ask for SOC 2, they will also ask about the Security Rule; the two are usually evidenced from the same controls.
