SOC 2 Trust Service Principles (TSP) are a set of criteria used to evaluate and assess the controls implemented by service organizations. These principles serve as the foundation for SOC 2 audits and reports. There are 61 criteria and approximately 300 points of focus for Trust Services. Here are the five main Trust Service Principles:
Privacy: Policy dictates the appropriate use, retention, collection, disclosure, and disposal of personally identifiable information (PII).
Security: Measures are in place to protect systems and data against unauthorized access, disclosure, and damage that could jeopardize the system's ability to achieve its objectives.
Confidentiality: Confidential information is safeguarded and secured in accordance with established protocols.
Processing Integrity: System processing ensures accuracy, validity, completeness, and timeliness, maintaining the integrity of customer data throughout data processing.
Availability: Controls are implemented to ensure the availability of information and systems, supporting the operational and strategic objectives of the company and its clients.
Organizations can choose which of the other trust services they’d like to include in the audit. Service organizations are evaluated against these Trust Service Principles to demonstrate their compliance with SOC 2 standards and provide assurance to customers and stakeholders regarding the effectiveness of their controls in these areas.
