SOC 2

« Back to Glossary Index

Introduction

In today’s digital landscape, where data breaches and cyber threats are rampant, securing customer data is paramount. This is where SOC 2, a security framework published by the American Institute of Certified Public Accountants (AICPA), comes into play. SOC 2 is crucial for organizations looking to ensure data integrity and protect customer information. Understanding SOC 2 is key to enhancing the security of your projects and building trust with your clients over a significant period of time.

What Is SOC 2?

SOC 2, or Service Organization Control 2, is more than just a report or an audit; it’s a framework of controls designed to safeguard customer data. While it’s a voluntary cybersecurity attestation, it’s particularly relevant for organizations with US-based customers and stakeholders. SOC 2 emphasizes the management of customer data based on five “trust service criteria,” which we’ll explore in-depth. It allows service providers and business partners to demonstrate their commitment to protecting sensitive customer information and maintaining a strong control environment.

The Five Trust Services Criteria

The five trust service criteria form the backbone of SOC 2 compliance:

  1. Security (Common Criteria): Ensures that systems are protected against unauthorized access. Controls include firewalls, intrusion detection systems, and multi-factor authentication.
  2. Availability: Ensures that systems are operational and accessible. This involves disaster recovery procedures and consistent system monitoring.
  3. Processing Integrity: Ensures accurate, complete, and timely processing of data through checks and balances.
  4. Confidentiality: Protects confidential information from unauthorized access using encryption and role-based access controls.
  5. Privacy: Governs the collection, use, and disposal of personal information per the organization’s privacy notice and AICPA criteria.

Comparison of Five Trust Services Criteria

Criteria Description Example Controls
Security Protecting information from unauthorized access Firewalls, MFA, IDS
Availability System accessibility and uptime Disaster recovery, uptime monitoring
Processing Integrity Accurate and timely data processing Data validation checks, error handling
Confidentiality Protection of confidential information Encryption, access restrictions
Privacy Proper handling of personal information Data anonymization, privacy policies

Types of SOC 2 Reports

  • Type 1 Report: Snapshot of systems and controls at a specific point in time. Focuses on the design and existence of controls.
  • Type 2 Report: Assesses operational effectiveness of controls over 6–12 months. Offers comprehensive assurance for enterprises.

The SOC 2 Audit Process

  1. Preparation Phase: Define audit scope and objectives.
  2. Select Auditor: Choose a CPA from a licensed firm.
  3. Evidence Collection: Gather documentation to show compliance.
  4. Audit: Auditor evaluates controls based on SOC 2 criteria.
  5. Post-Audit: Resolve issues and prepare for ongoing improvement.

SOC 2 Audit Timeline

Timeline Activities
6–12 Months Before Audit Readiness assessment, control gap identification
3–6 Months Before Audit Implement physical access and encryption controls
1–3 Months Before Audit Gather evidence and prepare documentation
During Audit Facilitate auditor’s examination
Post-Audit Review and act on audit findings

Implementing SOC 2 Controls

  • Develop Policies: Align policies with security and privacy principles.
  • Access Controls: Implement role-based access and 2FA.
  • Data Protection: Use AES encryption and backup protocols.
  • Risk Assessments: Identify risks and manage vendors.
  • Incident Response: Have a formal response plan in place.
  • Documentation: Maintain detailed records of controls.

Benefits of SOC 2 Compliance

  • Enhanced security posture
  • Competitive advantage
  • Increased customer trust
  • Streamlined third-party risk assessment
  • Alignment with regulatory requirements

SOC 2 vs. Other Compliance Frameworks

Framework Focus Area Region Industry-Specific?
SOC 1 Financial Reporting USA Yes
SOC 2 Data Security USA No
ISO 27001 Information Security Management International No
GDPR Data Protection EU No
HIPAA Healthcare Data Privacy USA Yes

Common Challenges

  • Resource limitations for small businesses
  • Technical hurdles in control implementation
  • Extensive documentation needs
  • Ongoing compliance maintenance
  • Managing audit and automation costs

SOC 2 Readiness Assessment

  • Self-Assessment: Evaluate internal controls
  • Gap Analysis: Identify and correct control deficiencies
  • Tools: Use platforms like Drata
  • Formal Assessment: Hire professionals for full evaluations

Maintaining SOC 2 Compliance

  • Continuous Monitoring: Regular checks on control effectiveness
  • Periodic Reviews: Update controls regularly
  • Change Management: Structured approach for business changes
  • Annual Recertification: Maintain certification through yearly audits

SOC 2 for Different Organization Types

  • Startups: Prioritize key controls
  • Mid-Size: Implement broader controls
  • Enterprises: Full-scale compliance programs
  • SaaS Providers: Focus on availability and data security
  • Fintech: Implement stringent privacy and security standards

Cost Considerations

Organization Size Audit Costs Implementation Costs Maintenance Costs
Small Business $5K–$10K $10K–$20K $5K–$10K
Mid-Size Company $20K–$40K $30K–$50K $10K–$20K
Enterprise $50K+ $100K+ $50K+
