Computer network abnormity detection and automatic restoration system and method and mobile terminal

Abstract

The invention discloses a computer network abnormity detection and automatic restoration system and method and a mobile terminal, and belongs to the technical field of computer network. The system comprises a network abnormity detection system which is used for performing computer network abnormity detection, a network automatic restoration system which is electrically connected with the network abnormity detection system and used for performing automatic restoration of the computer network abnormity and a network security isolation system which is electrically connected with the network abnormity detection system and used for performing security isolation of the computer network abnormity. The stability and the security of conventional detection can be guaranteed, the network security canbe effectively guaranteed by using two network cards of the intranet and the extranet and the detection system is arranged on each node of the network so that the protocol-based attack can be detected, the attacker is enabled not to transfer evidence easily, the detection real-time performance is high, the intrusion behavior can be restored and processed through the restoration processing moduleand the network restoration software module and thus the network security can be effectively guaranteed.

Description

technical field [0001] The invention relates to a computer network detection and repair method, in particular to a computer network anomaly detection and automatic repair system, method and mobile terminal, belonging to the technical field of computer networks. Background technique [0002] With the rapid development of computer networks, network threats and other network-related problems are increasing day by day, such as network attacks, data theft, viruses, worms, malicious port scanning activities, etc. The action speed of network threats is accelerated, the rate of change is faster, and more complex, Today, cyber threats infiltrate directly through computer networks despite perimeter defenses, so there are many tools for threat detection. [0003] Traditional detection includes simple or deep data packet inspection, which can usually be classified as intrusion detection and prevention equipment or anti-virus systems. Since the signature creation process is man-made, if...

Problems solved by technology

[0003] Traditional detection includes simple or deep data packet inspection, which can usually be classified as intrusion detection and prevention equipment or anti-virus systems. Since the signature creation process is human-operated, new cyber threat signatures appear or change, and the threat database cannot create new signatures in a timely manner.

[0004] At present, in the computer network, in order to ensure the stability and security of traditional detection, the use of a network card makes the network very unsafe, because various potential threats of the Internet will endanger the users of the LAN local area network and make all kinds of access to the network Audio, electrical appliances, security equipment, and even calls may be insecure. How to ensure network information security is very urgent and necessary
