SOC 2 (Service Organization Control 2)
Definition
SOC 2 is an auditing standard developed by the American Institute of CPAs (AICPA) that evaluates how service organizations manage and protect customer data. SOC 2 is designed for technology and cloud computing companies that store customer data, providing assurance that security controls are in place and effective.
Key Insight: SOC 2 is not a certification—it's an audit report that demonstrates your security posture to customers, investors, and partners. It's the gold standard for SaaS companies.
Why SOC 2 Matters
The Business Case
For Service Providers:
- ✅ Competitive Advantage: Many enterprises require SOC 2 before signing contracts
- ✅ Customer Trust: Demonstrates commitment to security
- ✅ Insurance Requirements: Lower cybersecurity insurance premiums
- ✅ Investor Confidence: Due diligence requirement for funding rounds
For Customers:
- ✅ Risk Mitigation: Third-party validation of security controls
- ✅ Compliance: Helps meet regulatory requirements (GDPR, HIPAA)
- ✅ Due Diligence: Reduce vendor risk assessments
Market Reality
Statistics:
- 65% of enterprise buyers require SOC 2 compliance
- Average time to first SOC 2: 6-12 months
- Average cost: $20,000 - $100,000 (audit fees + implementation)
- Annual recertification: Required
The Five Trust Service Criteria
SOC 2 evaluates security controls based on five Trust Service Criteria (TSC):
1. Security (Mandatory)
Definition: Protection against unauthorized access (both physical and logical)
Key Controls:
- Access control (RBAC, MFA, least privilege)
- Encryption (data at rest, data in transit)
- Network security (firewalls, VPNs, network segmentation)
- Vulnerability management (patching, penetration testing)
- Incident response plan
- Change management
- System monitoring and logging
Common Failures:
- No multi-factor authentication (MFA)
- Weak password policies
- Insufficient logging and monitoring
- No incident response plan documentation
2. Availability (Optional)
Definition: System is available for operation and use as agreed upon
Key Controls:
- Uptime monitoring (99.9% SLA)
- Disaster recovery plan (RTO/RPO)
- Backup and restore procedures
- High availability architecture
- Capacity planning
Example SLA:
Uptime Target: 99.9% (8.76 hours downtime/year)
RTO (Recovery Time Objective): 4 hours
RPO (Recovery Point Objective): 1 hour
Backup Frequency: Every 6 hours
Backup Retention: 30 days (daily), 1 year (monthly)
3. Processing Integrity (Optional)
Definition: System processing is complete, valid, accurate, timely, and authorized
Key Controls:
- Input validation
- Data integrity checks (checksums, hashes)
- Error handling and logging
- Transaction monitoring
- Reconciliation procedures
Example: Payment processor ensuring transactions are processed accurately without duplicate charges or data corruption.
4. Confidentiality (Optional)
Definition: Information designated as confidential is protected
Key Controls:
- Data classification (public, internal, confidential, restricted)
- Non-disclosure agreements (NDAs)
- Secure data disposal
- Confidential data handling procedures
Example: Legal software handling attorney-client privileged communications.
5. Privacy (Optional)
Definition: Personal information is collected, used, retained, disclosed, and disposed of per privacy policy
Key Controls:
- Privacy policy (GDPR, CCPA compliance)
- Consent management
- Data subject access requests (DSAR)
- Right to deletion (RTBF)
- Data breach notification procedures
Example: Marketing automation platform handling EU customer data under GDPR.
SOC 2 Type I vs Type II
Type I: Point-in-Time Assessment
Definition: Evaluates whether controls are designed appropriately at a specific point in time
Timeline: 1-3 months Report: Describes controls and tests design effectiveness Use Case: Initial compliance, proof of intent
Example Scope:
- Review policies and procedures (security policy, incident response plan)
- Inspect system configurations (firewall rules, access controls)
- Interview personnel (how processes work)
- Test a small sample of controls (1-2 instances)
Limitations: Doesn't prove controls work over time (only tests design, not operating effectiveness)
Type II: Operating Effectiveness Over Time
Definition: Evaluates whether controls are operating effectively over a period (typically 6-12 months)
Timeline: 6-12 months observation period + 2-3 months audit Report: Includes control design + operating effectiveness with evidence Use Case: Required by most enterprises, demonstrates sustained compliance
Example Scope:
- Continuous monitoring over 6-12 months
- Test control execution multiple times (e.g., 25 access control tests over 6 months)
- Review audit logs for entire observation period
- Verify incidents were handled per policy
Why Type II Matters: Proves controls work consistently, not just once for the auditor.
SOC 2 Audit Process
Phase 1: Preparation (2-4 Months)
Activities:
- Gap Assessment: Compare current state vs SOC 2 requirements
- Remediation: Implement missing controls
- Documentation: Write policies, procedures, runbooks
Common Gaps:
- No formal security policy
- Insufficient access controls
- Missing incident response plan
- Inadequate logging and monitoring
Phase 2: Readiness Assessment (1 Month)
Purpose: Mock audit to identify issues before the real audit
Activities:
- Auditor performs sample testing
- Identifies control weaknesses
- Provides remediation guidance
- Re-test after fixes
Cost: $5,000 - $15,000 (optional but highly recommended)
Phase 3: Audit (1-3 Months)
Activities:
- Opening Meeting: Scope clarification, timeline agreement
- Control Testing: Auditor tests each control (Type I: once, Type II: multiple times)
- Evidence Collection: Request documentation, screenshots, logs
- Interviews: Speak with personnel (engineers, security team, executives)
- System Walkthroughs: Observe processes in action
Evidence Examples:
- Access control: Screenshots of user permissions, MFA settings
- Encryption: TLS configuration files, database encryption proofs
- Monitoring: SIEM dashboard screenshots, alert configurations
- Incident response: Incident tickets, post-mortem reports
Phase 4: Report (2-4 Weeks)
Report Sections:
- Management Assertion: Company's statement about control design
- Auditor Opinion: Independent assessment of controls
- System Description: Infrastructure, processes, policies
- Control Objectives: TSC categories being evaluated
- Control Activities: Specific controls tested
- Test Results: Pass/fail for each control
- Exceptions: Controls that failed (if any)
Report Types:
- Unqualified Opinion: All controls passed (best outcome)
- Qualified Opinion: Some controls failed or insufficient evidence
- Adverse Opinion: Significant control failures (rare, very bad)

Common SOC 2 Failures and How to Avoid Them
1. Insufficient Evidence
Problem: Auditor asks for proof, you can't provide it Example: "Show me evidence that backups were tested in May 2024" → No documentation found
SpecWeave Solution:
# Every backup test creates an increment with evidence
/specweave:increment "Quarterly backup restoration test - Q2 2024"
# Spec.md documents procedure
# Tasks.md includes test steps
# Completion report includes:
# - Backup file restored: backup-20240501.sql
# - Restoration time: 45 minutes
# - Data integrity check: 100% (no corruption)
# - Screenshot: tests/evidence/backup-restore-20240501.png
2. Undocumented Changes
Problem: Production changes with no approval trail Example: Engineer deployed encryption change without review → Auditor flags as control failure
SpecWeave Solution: Every production change = increment
Increment: 0032-tls-upgrade
Approval: CTO + Security Lead (documented in spec)
Testing: Embedded tests in tasks.md (100% pass)
Deployment: Completion report with deployment log
Rollback: Plan documented in plan.md
3. No Incident Response Evidence
Problem: Claim to have incident response plan, but never executed it Example: Auditor asks "Show me your last 3 incidents" → No post-mortems found
SpecWeave Solution:
# Every incident = increment
/specweave:increment "Incident 003: DDoS attack on API gateway"
# Spec.md: What happened, impact, timeline
# Plan.md: Mitigation steps, root cause
# Tasks.md: Remediation tasks (add rate limiting, update WAF)
# Completion report: Evidence of fixes deployed
4. Missing Security Training
Problem: No proof employees received security training Example: Auditor asks for training attendance records → HR has no records
SpecWeave Solution:
File: .specweave/increments/0040-security-training-q1-2025/spec.md
# Increment 0040: Q1 2025 Security Awareness Training
## Participants
- All employees (42 total)
- New hires (3)
## Training Topics
- Phishing awareness
- Password best practices
- Incident reporting
## Completion Report
- Date: 2025-01-20
- Attendance: 100% (42/42)
- Quiz scores: Average 95% (passing: 80%)
- Evidence: training-completion-certificates-q1-2025.pdf
