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 CC6.3) and look for objective evidence on the latest two assessment cycles. ## How to implement 1. Write a short policy stating intent, scope and named owner. 2. Encode it as a platform guardrail — SCP, Azure Policy initiative, Organisation Policy, or repository policy. 3. Wire a monitoring signal that catches drift (CSPM rule, SIEM rule, scheduled query, Workspace alert) and ticket it. 4. Review on a documented cadence and capture the review in the risk register or compliance tracker. ### Operational checklist - **Information.** Document the trigger, the owner and the cadence. - **Access.** Document the trigger, the owner and the cadence. - **Security.** Document the trigger, the owner and the cadence. - **Management.** Document the trigger, the owner and the cadence. - **Data.** Document the trigger, the owner and the cadence. - **Scope:** objectives, modification, management. ## Evidence to collect - **Identity Scan.** IAM / IdP exports — Entra ID, Okta, IAM Identity Center, Workspace directory — showing accounts, roles, MFA state and last sign-in. - **Infra Scan.** Continuous infrastructure-posture telemetry — AWS Config, Azure Policy compliance, GCP Organisation Policy, Wiz / Prisma findings. Identity analytics (Okta, SailPoint, Access Analyzer) demonstrates least-privilege. Focus: Access Modification (Original component: Logical and Physical Access Controls). ## 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.8.23** — Web filtering](https://support.icompaas.com/compliance/iso-27001-2022/a-8-23-web-filtering) - [**NIST SP 800-171 Rev. 3 3.13.4** — Information in Shared System Resources](https://support.icompaas.com/compliance/nist-sp-800-171-rev-3/3-13-4-information-in-shared-system-resources) - [**CIS Controls v8 9.2** — Use DNS Filtering Services](https://support.icompaas.com/compliance/cis-controls-v8/9-2-use-dns-filtering-services) - [**ISO/IEC 27701:2025 A.3.8** — Identity management](https://support.icompaas.com/compliance/iso-27701-2025/a-3-8-identity-management) - [**BSI C5:2020 AM-05** — Commitment to Permissible Use, Safe Handling and Return of Assets](https://support.icompaas.com/compliance/bsi-c5-2020/am-05-commitment-to-permissible-use-safe-handling-and-return-of-assets) ## Related controls in SOC 2 (2017 TSC) - [**Criterion CC1.5** — Accountability for Internal Control Responsibilities](https://support.icompaas.com/compliance/soc-2-trust-services-criteria/cc1-5-accountability-for-internal-control-responsibilities) - [**Criterion CC6.5** — Asset Disposal](https://support.icompaas.com/compliance/soc-2-trust-services-criteria/cc6-5-asset-disposal) - [**Criterion CC6.1** — Logical Access Controls](https://support.icompaas.com/compliance/soc-2-trust-services-criteria/cc6-1-logical-access-controls) - [**Criterion CC6.2** — Access Provisioning](https://support.icompaas.com/compliance/soc-2-trust-services-criteria/cc6-2-access-provisioning) - [**Criterion CC6.6** — Boundary Protection](https://support.icompaas.com/compliance/soc-2-trust-services-criteria/cc6-6-boundary-protection) - [**Criterion CC6.8** — Malicious Code Protection](https://support.icompaas.com/compliance/soc-2-trust-services-criteria/cc6-8-malicious-code-protection) ## 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 CC6.3` Topics: identity accessidentity managementaccess reviewprivileged accessnetwork segmentation ## 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.
