The Device Authentication Module (DAM) employs an agent deployed on terminal devices to conduct hardware or software protection level checks on the devices. It not only verifies the trustworthiness of connected devices during device onboarding but can also be applied in resource access scenarios. Through integration with identity authentication vendors, it provides comprehensive security measures. This module offers device management functionalities such as addition, locking, and deletion, while also providing device health information, dashboard statistics, and authentication history query capabilities. It generates events to notify administrators in case of authentication failures.
