Automatic construction system and method for access control strategy of high-level information system

Abstract

The invention discloses an automatic construction system and method for an access control strategy of a high-level information system. According to the scheme, information resource acquisition is carried out on software and hardware products in a whole network system based on an information resource acquisition module, an access control mechanism hierarchical division module, a subject-object andrelationship carding module, a high-level demand gradual essence module, an automatic strategy generation module and an information resource acquisition module; the access control mechanism hierarchical division module performs hierarchical division on an access control mechanism; the subject-object and relationship carding module caries a subject, an object and a relationship structure thereof byanalyzing the subject, the object and the relationship structure thereof in the whole network system; the high-level demand gradual essence module is used for gradually refining the essence service access demand and the operation and maintenance management access demand; and the automatic strategy generation module generates an access control strategy of each access control mechanism level. According to the scheme, in the resource access process of a network system user, accurate access control can be carried out on the user no matter what level access is carried out.

Description

technical field [0001] The invention relates to network security level protection technology, in particular to network system access control technology. Background technique [0002] At present, the access control points in the entire network system are independent and have no connection with each other, resulting in the phenomenon of "no correlation, no integrity, and no consistency" in access control during the process of user access to resources. It is reflected in the following two aspects: [0003] 1) Omissions in access control [0004] That is, users are not allowed to access at a higher level, but are allowed to access at a lower level, so that the user's access control to resources can be bypassed. For example, in an FTP-based application system, according to regulations, a user does not have the ability to "write" a file. When a user logs in through an FTP client to access the file, the "write" operation to the file is not allowed. , but when the user directly l...

Problems solved by technology

For example, in an FTP-based application system, according to regulations, a user does not have the ability to "write" a file. When a user logs in through an FTP client to access the file, the "write" operation to the file is not allowed. , but when the user directly logs in to the operating system, he can "write" the file, resulting in omissions in access control

[0005] 2) Conflicts in access control

[0006] That is, the user is allowed to perform access control at a higher level, but not allowed at a lower level, resulting in failure of use
