Information network virus intrusion detection system and method

Abstract

The invention discloses an information network virus intrusion detection system and method, and relates to the technical field of information networks. The host unit is in network connection with a firewall through an intranet router, the firewall is in network connection with an extranet through an extranet router, and the firewall is in bidirectional electrical connection with the central processing unit. The output end of the central processing unit is bidirectionally and electrically connected with the input ends of a data transmission unit, a data encryption unit and a virus isolation unit, the firewall is electrically connected with a DMZ area, and the DMZ area is electrically connected with a network threat engine III, a server I and a server II. The information network virus intrusion detection system and the information network virus intrusion detection method are high in safety, can realize detection, isolation, searching and killing of network viruses, can encrypt network data, can encrypt and transmit the data, effectively prevent data leakage, and further improve the safety performance of information network data transmission.

Description

technical field [0001] The invention relates to the technical field of information network, in particular to an information network virus intrusion detection system and method thereof. Background technique [0002] As the network security risk factor continues to increase, the firewall, once the most important means of security prevention, can no longer meet people's needs for network security. With the rapid development of computer network technology and the Internet, network attacks and intrusions are increasing day by day, especially In the past two years, the computer networks of government departments, military agencies, financial institutions, and enterprises have been frequently attacked by hackers. Attackers can calmly attack and intrude on those networks without security protection, such as denial of service attacks, unauthorized access, wanton theft and tampering of important data information, installation of backdoor monitoring programs to obtain internal informat...
