intrusion prevention system based on security policy at three levels

摘要

the solution proposed in this paper is the establishment of a system of intrusion pru00e8vention (spi) based on a security policy at three levels.each level contributes to the protection of the information system (is) of the internal and external attacks and attacks, the first level is the use of a sensor based network intrusion detection system (nests), the second level.is the implementation of a security policy function allowing users to access applications and data only via the rules of safety.finally, the third level is the implementation of a policy of su00e9curitu00e8 via a linking mechanism, operational data of the access control list and the list of physical and logical access control to the machine component.
