Intrusion detection system and method based on role access control

Abstract

The present invention provides an intrusion detection system and method based on role access control. The system comprises a network environment detection module which is used for performing intrusionsecurity detection on the access of a user and / or filtering and purifying the application information of the user, a role management module which is used for judging whether the operation of the userexceeds an authority assigned by a role assigned to the user, a system resource allocation module which is used for allocating system resources to the user according to the role of the user, and a monitoring module which is used for judging whether the working in the system is normal or not according to abnormal activities in the network environment detection module, the role management module and / or the system resource allocation module. According to the intrusion detection system based on role access control, the function of an intrusion detection system is further improved, the probabilityof occurrence of errors is reduced, and the security of the system is ensured.

Description

【Technical field】 [0001] The invention relates to the field of network security, in particular to an intrusion detection system based on role access control and its working method. 【Background technique】 [0002] The computer structure tends to be simple and easy to carry, technological innovation promotes the rapid development of the network, network security has gradually become a new discipline, and network security has penetrated into all aspects of life. It is a combination of computer science, network technology, communication technology, and information security technology. Large-scale and highly complex development and transformation of the network, through the monitoring, investigation and application of the network, the probability of network intrusion is reduced, and the risk of property information leakage is reduced. At present, the main ways of network intrusion include hacker intrusion, system backdoor intrusion, computer virus intrusion, denial of service att...

AI Technical Summary

Problems solved by technology

At present, the main ways of network intrusion include hacker intrusion, system backdoor intrusion, computer virus intrusion, denial of service attack, internal leak, logic bomb, information loss and password cracking, etc. Traditional network protection is based on firewall technology , the rest of the network technology can no longer meet the needs of daily life
