In practice, this means you can prove you information management-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. This control is rated **high**. Auditors expect a named owner, a remediation SLA, and a tooling artefact that evidences continuous operation. ## 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 **Privacy**, the assessor will trace your implementation back to the catalogue reference (Criterion P4.1) and look for objective evidence on the latest two assessment cycles. ## How to implement #### 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. - **Risk.** Document the trigger, the owner and the cadence. - **Management.** Document the trigger, the owner and the cadence. - **Privacy.** Document the trigger, the owner and the cadence. - **Personal.** Document the trigger, the owner and the cadence. - **Scope:** management. ## Evidence to collect - **Policy Document.** A signed and version-controlled policy / standard / procedure document. Signed policy or standard documents the safeguard. Focus: Limitation of Personal Information Use to Defined Purposes (Original component: Privacy). ## 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.5.5** — Contact with authorities](https://support.icompaas.com/compliance/iso-27001-2022/a-5-5-contact-with-authorities) - [**India DPDP Act 2023 LB-001** — Consent Quality & Management](https://support.icompaas.com/compliance/india-dpdp-act-2023/lb-001-consent-quality-management) - [**GDPR Article 2** — Material Scope](https://support.icompaas.com/compliance/gdpr/article-2-material-scope) - [**NIST SP 800-53 Rev. 5 PL-2(3)** — Plan And Coordinate With Other Organizational Entities](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/pl-2-3-plan-and-coordinate-with-other-organizational-entities) - [**HIPAA (45 CFR Part 164) 164.308(a)(5)(i)** — Security Awareness and Training](https://support.icompaas.com/compliance/hipaa/164-308-a-5-i-security-awareness-and-training) ## Related controls in SOC 2 (2017 TSC) - [**Criterion P3.2** — Consent Management for Personal Information Collection](https://support.icompaas.com/compliance/soc-2-trust-services-criteria/p3-2-consent-management-for-personal-information-collection) - [**Criterion P3.1** — Personal Information Collection Aligned with Privacy Objectives](https://support.icompaas.com/compliance/soc-2-trust-services-criteria/p3-1-personal-information-collection-aligned-with-privacy-objectives) - [**Criterion P4.3** — Secure Disposal of Personal Information](https://support.icompaas.com/compliance/soc-2-trust-services-criteria/p4-3-secure-disposal-of-personal-information) - [**Criterion P7.1** — Maintenance of Accurate and Relevant Personal Information](https://support.icompaas.com/compliance/soc-2-trust-services-criteria/p7-1-maintenance-of-accurate-and-relevant-personal-information) - [**Criterion P8.1** — Inquiry and Complaint Management Process](https://support.icompaas.com/compliance/soc-2-trust-services-criteria/p8-1-inquiry-and-complaint-management-process) - [**Criterion P1.1** — Privacy Notice to Data Subjects](https://support.icompaas.com/compliance/soc-2-trust-services-criteria/p1-1-privacy-notice-to-data-subjects) ## 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 P4.1` Topics: governance riskprivacy managementpolicy 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.
