Abstract

The present invention relates to a method and device for controlling mandatory access. The method includes: configuring the access authority of the subject and object of the terminal equipment being accessed to obtain a configuration file; the configuration file includes a subject field and an object field, and the subject field corresponds to a There is at least one subject, and the object field corresponds to at least one object; obtain the user's access request to the accessed terminal device; the access request carries the user's access right, the first attribute information used to characterize the access subject, and the first attribute information used to characterize the accessed terminal device. The second attribute information of the object; load the configuration file, and determine the target subject domain and target object domain corresponding to the user according to the preset mapping relationship and the first attribute information and second attribute information included in the access request; based on the The user's access rights and the target subject domain's access rights to the target object domain determine whether the user's access request is allowed. The solution of the present invention can satisfy various application scenarios of users.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for controlling mandatory access. Background technique [0002] A conventional model, such as the windows access control model (AccessControlModel), is divided into two parts: access token (AccessToken) and security descriptor (SecurityDescriptor), which are things owned by the visitor and the visitor respectively. The access token is associated with a specific Windows account, so when the same account accesses other files with the same security descriptor, the permissions on the accessed objects are the same, which cannot meet the mandatory access control requirements. [0003] The traditional mandatory access security model (such as BLP, BIBA model) simply divides users and accessed files into extremely high, high, medium, low, and very low levels, and the permissions are relatively single, so they cannot satisfy users. various application scenarios.
