The Trust Inference Module (TIM) utilizes an inventory of device information, including the operating system, antivirus software, installed applications, and potential security vulnerabilities, as the basis for assessing device security. The collected security data, combined with identity authentication and device authentication, serves as the criteria for assessing trust scores during resource access. The decision controller determines the access outcome based on these trust scores. This module includes functionalities such as device security inspection, trust score information, dashboard statistics, and historical records.
