Soc 2 Compliance Checklist

Standard Operating Procedure: Free SOC 2 Compliance Checklist

1. Document Control & Revision History

2. Executive Summary & Scope

Purpose: To provide a formalized, structured roadmap for achieving SOC 2 Type II compliance through internal controls assessment and artifact collection. Scope: This procedure applies to all internal IT, Engineering, and HR functions within the organizational boundary. It addresses the AICPA Trust Services Criteria (TSC) specifically focusing on Security, Availability, and Confidentiality. Operational Boundary: Extends from initial gap analysis to the final bridge letter generation, excluding third-party penetration testing engagements.

3. Prerequisites & Tool Requirements

• Software/Platforms:
  • Centralized GRC (Governance, Risk, and Compliance) platform or version-controlled repository (Git).
  • Identity & Access Management (IAM) suite (e.g., Okta, JumpCloud).
  • Endpoint Management (e.g., MDM/Jamf).
• Certifications/Knowledge: Personnel must have foundational understanding of NIST CSF or ISO 27001 frameworks.
• Documentation: Access to existing Information Security Policies, Employee Handbook, and System Architecture Diagrams.

4. Roles & Responsibilities (RACI Matrix)

5. Step-by-Step Operational Procedure

Phase I: Internal Control Definition

• Define and document the "System Description" (data flows, infrastructure, and sub-service organizations).
• Perform internal risk assessment against SOC 2 TSC.
• Map existing controls to TSC requirements.

Phase II: Policy and Evidence Collection

• Formalize Information Security Policies (Access Control, Change Management, Incident Response).
• Audit user access lists (confirm quarterly review cycle is active).
• Gather evidence of background checks for all personnel with system access.
• Verify log aggregation status (ensure cloud-native logs are shipping to a centralized SIEM).

Phase III: Remediation and Validation

• Close control gaps identified in Phase I.
• Conduct internal audit to ensure policy alignment with operational reality.
• Retain evidence (screenshots, logs, export reports) in a tamper-evident audit repository.

6. Quality Assurance & Verification Criteria

• Tolerance Threshold: Zero tolerance for critical/high-risk vulnerabilities in production environments.
• Evidence Integrity: All audit artifacts must be timestamped and verifiable via cryptographic hash if requested by an auditor.
• Acceptance Benchmarks:
  • 100% of employees have completed Security Awareness Training.
  • MFA enforced on all production environment access points (100% saturation).
  • Change Management documentation reflects 100% peer-review status for production code merges.

7. Practical Troubleshooting Scenarios

Scenario 1: Audit fails to locate specific evidence (e.g., legacy access logs).

• Protocol: Immediately flag as a "Control Deficiency." Document the root cause, implement a compensatory control (e.g., manual snapshot verification), and update the log retention policy within 24 hours.

Scenario 2: Employee turnover resulted in lapsed access for offboarded accounts.

• Protocol: Initiate an "Emergency IAM Reconciliation." Immediately disable orphaned accounts. Audit the "Access Termination Checklist" process and retrain the HR/IT liaison within one business week.

Scenario 3: Unauthorized code change found in production logs.

• Protocol: Initiate Incident Response Plan (IRP). Perform immediate rollback to the last verified stable state. Conduct a Root Cause Analysis (RCA) and enforce mandatory PR approval requirements in the CI/CD pipeline.
