✅ SOC 2 Trust Service Criteria Mapping

OWASP Top 10 → Service Organization Control 2 Audit Standards

Overview

This document maps OWASP Top 10 Web Application Security Risks to SOC 2 Trust Service Criteria (TSC). SOC 2 is an auditing procedure that ensures service providers securely manage data to protect the interests of the organization and the privacy of its clients.

SOC 2 Trust Service Criteria

SOC 2 is based on five Trust Service Criteria:

Detailed Mapping

01. Broken Access Control

CC6.6 Logical access security measures prevent unauthorized access Authentication and authorization mechanisms
CC7.2 System monitoring detects and identifies anomalies Access control monitoring and alerting

02. Cryptographic Failures

CC7.2 System monitoring detects configuration changes Configuration drift detection
CC8.1 Changes are tested before implementation Configuration testing procedures

06. Vulnerable and Outdated Components

SOC 2 Criteria Control Description Implementation
CC7.1 System components are identified and managed Software inventory management
CC7.2 Security events are monitored Vulnerability monitoring
CC8.1 System changes are tested Patch testing procedures
A1.2 System availability is monitored Dependency health monitoring

07. Identification and Authentication Failures

SOC 2 Criteria Control Description Implementation
CC6.1 Users are authenticated before access Multi-factor authentication (MFA)
CC6.2 User registration and authorization procedures Identity verification processes
CC6.6 Security measures prevent unauthorized access Strong password policies
CC6.7 Credentials are encrypted and protected Credential storage security

08. Software and Data Integrity Failures

SOC 2 Criteria Control Description Implementation
CC8.1 Changes are authorized, tested, and approved CI/CD pipeline security
PI1.1 Processing integrity policies exist Code signing procedures
PI1.3 Processing is complete and accurate Integrity verification
PI1.5 Stored information is complete and accurate Data integrity checks

09. Security Logging and Monitoring Failures

SOC 2 Criteria Control Description Implementation
CC7.2 Security events are detected and monitored SIEM implementation
CC7.3 Security events are analyzed and responded to Incident response procedures
CC7.4 System is monitored for capacity Log storage and retention
CC7.5 System incidents are identified and managed Alerting and escalation procedures

10. Server-Side Request Forgery (SSRF)

SOC 2 Criteria Control Description Implementation
CC6.6 Security measures prevent unauthorized access Network segmentation
CC6.7 Infrastructure is protected Firewall and network controls
CC7.2 Security events are monitored Network traffic monitoring
PI1.4 Processing is valid URL validation and allowlisting

Audit Preparation

Documentation Required

For each OWASP vulnerability addressed:

  1. Control Description: How the control prevents/detects the vulnerability
  2. Implementation Evidence: Configuration, code, policies
  3. Operating Effectiveness: Logs, reports showing controls work
  4. Testing Results: Security testing demonstrating effectiveness
  5. Exception Handling: How deviations are managed

Sample Control Testing

Example: Testing CC6.1 for Broken Access Control

Control: Role-based access control prevents unauthorized access

Test Steps:

  1. Review RBAC configuration
  2. Test access with various user roles
  3. Attempt unauthorized access
  4. Review access logs
  5. Verify least privilege implementation

Expected Results:
