What is Required for Soc 2 Compliance

Standard Operating Procedure: SOC 2 Compliance Lifecycle

1. Document Control & Revision History

2. Executive Summary & Scope

Executive Summary

SOC 2 (System and Organization Controls 2) compliance validates the operational efficacy of an organization's internal controls regarding security, availability, processing integrity, confidentiality, and privacy. This SOP establishes the institutional rigor required to achieve and maintain an unmodified audit opinion.

Operational Scope

This policy applies to all systems, infrastructure, personnel, and third-party vendors identified as "in-scope" for the selected Trust Services Criteria (TSC). The primary objective is to move from ad-hoc compliance to a "continuous monitoring" posture.

3. Prerequisites & Tool Requirements

• Certification Readiness: Management review of the internal control environment.
• Infrastructure: Defined, documented, and hardened network perimeter (AWS/Azure/GCP environment).
• Software Stack:
  • Compliance Automation: (e.g., Vanta, Drata, or Anecdotes) for evidence collection.
  • IAM: Centralized Identity Provider (IdP) (e.g., Okta, Azure AD) with mandatory Multi-Factor Authentication (MFA).
  • Endpoint Management: Mobile Device Management (MDM) (e.g., Jamf, Kandji) for encrypted disk enforcement.
• Documentation: Established Security Policy Framework (AUP, Access Control, Incident Response).

4. Roles & Responsibilities (RACI Matrix)

5. Step-by-Step Operational Procedure

Phase I: Scoping and Gap Analysis

• Define the System Description and specific TSCs (Security is mandatory; others are optional).
• Identify all internal/external assets (servers, databases, API endpoints) in scope.
• Conduct a gap analysis against the AICPA Trust Services Criteria.

Phase II: Control Implementation

• Enforce MFA across all production systems and SaaS platforms.
• Automate evidence collection for access reviews (Quarterly requirement).
• Configure centralized logging/SIEM to capture system anomalies.
• Execute background checks for all personnel with system access.

Phase III: Audit Execution

• Engage a CPA firm for the formal Type I (Point-in-time) or Type II (Operational period) audit.
• Provide requested "Evidence Artifacts" via secure compliance portal.
• Participate in management walkthroughs and interview sessions.

6. Quality Assurance & Verification Criteria

• Acceptance Benchmarks:
  • Control Operating Effectiveness: 0% failure rate on critical access controls.
  • Evidence Integrity: All uploaded artifacts must be timestamped and cryptographically linked to the control owner.
  • Tolerance Threshold: Zero "Material Weaknesses." Maximum of one "Significant Deficiency" requiring a remediation plan within 30 days.
• Verification: Monthly "Pre-Audit" checks to be performed by the Compliance Lead to ensure policy adherence.

7. Practical Troubleshooting Scenarios

Scenario A: Unauthorized Access Detected

• Condition: An automated alert triggers for an unauthorized login attempt on a production database.
• Immediate Protocol:
  1. Suspend user credentials immediately via IdP.
  2. Isolate the affected instance from the network.
  3. Initiate Incident Response Plan (IRP) documentation; log all actions as evidence for the auditor.

Scenario B: Evidence Gap identified in Audit

• Condition: Auditor identifies that Q3 User Access Reviews were not documented.
• Immediate Protocol:
  1. Perform a "Look-back" review immediately.
  2. Document the current state of all user permissions.
  3. Implement a compensating control (e.g., manual sign-off by manager) and add the corrective action to the Risk Register to prevent recurrence.

Scenario C: Personnel Departure without Offboarding

• Condition: Employee exits the company, but accounts remain active.
• Immediate Protocol:
  1. Identify all active sessions and tokens for the individual.
  2. Execute global deprovisioning via MDM/IdP.
  3. Perform an emergency audit of the individual's access history to ensure no unauthorized changes were made during the oversight window.
