Trust Services Principles and Criteria

Overview
Trust Services are a set of professional attestation and advisory services based on a core set of principles and criteria that address the risks and opportunities of IT-enabled systems and privacy programs. The following principles and related criteria are used by practitioners in the performance of Trust Services engagements:


 * Security. The system is protected against unauthorized access (both physical and logical).
 * Availability. The system is available for operation and use as committed or agreed.
 * Processing integrity. System processing is complete, accurate, timely, and authorized.
 * Confidentiality. Information designated as confidential is protected as committed or agreed.
 * Privacy. Personal information is collected, used, retained, disclosed and destroyed in conformity with the commitments in the entity’s privacy notice and with criteria set forth in Generally Accepted Privacy Principles issued by the AICPA and CICA.

The Trust Services Principles and Criteria (TSPC) of security, availability and processing integrity are used to evaluate whether a system is reliable.
