Computer access control system of centralized management

Abstract

The invention discloses a computer access control system of centralized management. The system includes: a centralized computer machine room; a local-end gateway, which converts computer peripheral ports to network data stream; a network switch; a content reviewing and authentication system, which is used for auditing network data packets; and a user gateway, which converts network data stream tothe computer peripheral ports. The local-end gateway can carry out network accesses, port conversion, video encoding and system management. The user gateway can carry out network accesses, port conversion, video decoding and system management. The content reviewing and authentication system can carry out network monitoring, authentication and log storage. According to the system, the problem thatexisting access control and reviewing systems cannot perfectly and effectively manage and control users is solved, and promotion and application are facilitated.

Description

technical field [0001] The invention relates to the fields of electronic technology, communication technology and computer, in particular to a centralized management computer access control system. Background technique [0002] With the rapid development of today's computer technology, all walks of life use tens of thousands of computers for calculation and processing, and enjoy the informationization convenience provided by application software and data processing. However, information security issues follow, such as illegal use, virus Security risks such as malicious attacks and malicious attacks have always threatened the information security of governments, enterprises and institutions, especially related organizations with confidentiality needs. User data urgently needs security protection, and users urgently require comprehensive access control security policies. [0003] The research of access control system is how to construct a system that reasonably assigns rights ...

AI Technical Summary

Problems solved by technology

However, the existing computer access control system is easy to crack through software, occupies the resources of the target computer system, runs slowly and has low efficiency, and cannot prevent the user from cracking the target computer system at the hardware level. The hardware takes up a lot of space, which is not conducive to monitoring all operations of the user on the target computer, cannot block the illegal operation of the computer by the user in real time, and leave a complete operation log of the user on the computer
