A central managed network adaptor

Abstract

The invention discloses a network adaptor to be central managed, which comprises the following parts: main processor, network chip, memory chip, reserving element and power element, wherein the functional mode of main processor contains network data transmitting unit, safe functional unit, central managing control unit and host system interface unit. The invention operates independently corresponding to host system, which interconnects network data and host system through PCI interface, therefore affirming the illegal interpolation, stopping and evasion by host system under central management.

Description

technical field [0001] This invention relates to computer communications equipment, and more particularly, to network adapters as components of computers. Background technique [0002] With the wide application of the Internet, the problem of information security guarantee is the basic and fundamental problem that must be solved in the construction of information system. [0003] Existing security solutions usually deploy multiple devices such as firewalls, VPNs, intrusion detection systems, security isolation systems, and load balancing devices at the border between the Internet and the intranet to achieve network layer security. The identity authentication server is deployed on the intranet to implement certificate-based identity authentication. The application (such as Web) server implements mandatory access control through the configuration of operating system roles and permissions, implements active application access control through application software, and implement...

Problems solved by technology

In this mode, due to the insecurity of the host system, when the host system is invaded, the attacker can illegally modify the security policy of the network adapter, or even stop the security function of the network adapter.

In this mode, it is still unable to meet the strict security requirements
