Introduction
Security Computer
The security computer is a trusted and intelligent computing terminal with the functions of computing and protection. Based on the protection of hardware encryption chip authentication, it carries out real-time monitoring and scanning for ports, and constructs a complete trust chain for switching, application execution, and peripheral ports control, so as to implement overall control for the computing behaviors of the internal network and the external network, and thoroughly protect the confidentiality and integrity of high-level network systems.
Features
