SOC 2 Security Controls Overview

SOC 2 security controls, also known as Common Criteria (CC), are mandatory for all SOC 2 audits and form the foundation of your compliance program. These controls are organized into eight categories that address different aspects of information security and risk management.

What Are Security Controls?
  • Specific measures designed to reduce security risks
  • Policies, procedures, and technical implementations
  • Both preventive and detective in nature
  • Must be operating consistently and effectively
Control Objectives
  • Protect against unauthorized access
  • Ensure system availability and reliability
  • Maintain data integrity and confidentiality
  • Support business operations and compliance
Control Category Control ID Primary Focus Implementation Priority Complexity Level
Control Environment CC1 Governance and culture High Medium
Communication & Information CC2 Information flow and communication Medium Low
Risk Assessment CC3 Risk identification and management High High
Monitoring Activities CC4 Control effectiveness monitoring High High
Control Activities CC5 Operational control procedures High Medium
Logical & Physical Access CC6 Access management and restrictions High High
System Operations CC7 System management and operations High High
Change Management CC8 System and process changes Medium Medium

Access Controls (CC6)

Access controls are fundamental to SOC 2 compliance, ensuring that only authorized individuals can access systems, applications, and data. This category includes both logical and physical access controls.

CC6.1

User Access Provisioning

Objective: The entity implements logical access controls to restrict access to systems, applications, and data to authorized users.

Implementation Steps:
  1. Access Request Process: Establish formal procedures for requesting system access

  3. Role-Based Access: Define roles and assign permissions based on job functions
  4. Provisioning Tools: Use automated tools for consistent access provisioning
  5. Documentation: Maintain records of all access requests and approvals
Best Practices:
  • Implement least privilege principle - grant minimum necessary access
  • Use standardized access request forms with clear business justification
  • Establish maximum timeframes for access provisioning (e.g., 24-48 hours)
  • Create exception handling procedures for emergency access requests
Maturity Level:
Level 3 - Defined
CC6.2

User Access Modification and Termination

Objective: The entity modifies or removes access in a timely manner when changes occur in job responsibilities or employment status.

Implementation Steps:
  1. HR Integration: Connect HR systems with access management tools
  2. Automated Workflows: Implement automated deprovisioning upon termination
  3. Role Change Procedures: Establish processes for access modification during role changes

Best Practices:
  • Implement immediate access suspension for terminated employees
  • Use termination checklists to ensure all access is properly removed
  • Monitor for orphaned accounts and inactive users
  • Establish procedures for temporary access suspension during extended leave
CC6.3
