Problems solved by technology

According to the method of adding SELinux authorization according to the log information, the application needs to be tested in advance to obtain the log information, and the test is a very time-consuming operation, and the way of manually adding SELinux authorization is obviously inefficient, and it is harmful to developers. There are high requirements for qualifications, and currently most developers do not have this ability

Embodiment 1

[0043] figure 1 It is a schematic flowchart of a method for generating an authorization configuration file provided in Embodiment 1 of the present invention. The method for generating an authorization configuration file provided in this embodiment is applicable to the scenario of automatically performing SELinux authorization on programs on the Android platform, so as to ensure the security of the Android system. The SELinux authorization syntax format is: allow subType(:process) objType:objResType permission, which means: allow the subType type of authorization subject (usually a certain type of process) to have certain permissions on objects of type objType:objResType ( Specifically, the permission is, for example, operations such as reading or writing). The technical solution of the embodiment of the present invention aims to determine the target fields (subType, objType, objResType, and permission) in the authorization syntax format through an automated way of source code...

Embodiment 2

[0093] image 3 It is a schematic structural diagram of an apparatus for generating an authorization configuration file provided by Embodiment 2 of the present invention. see image 3 As shown, the device includes: a first determination module 310, a second determination module 320, an analysis module 330, an authorization statement generation module 340 and an authorization configuration file generation module 350;

[0094] Among them, the first determination module 310 is used to determine the source code authorization mapping table, and the source code authorization mapping table includes the functions with standard functions that are allowed to be matched, the object types that are allowed to be operated, and the allowed operation types. Mapping relationship; the second determination module 320 is used to determine the security context file, and the security context file includes the owner type to which the operated object is allowed to operate; the parsing module 330 is ...

Abstract

The embodiment of the invention discloses an authorization configuration file generation method and device, equipment and a storage medium, and the method comprises the steps: determining a source code authorization mapping table which comprises a function which is allowed to be matched and has a standard function, an object type which is allowed to be operated by the function, and a mapping relation between allowed operation types; determining a security context file, wherein the security context file comprises an owner type to which the operated object allowed to be operated belongs; analyzing a to-be-authorized application program, and combining the source code authorization mapping table and the security context file through a key field identification technology to obtain each target field in an authorization syntax format; filling each target field into a corresponding position of the authorization grammar format to generate an authorization statement; and generating an authorization configuration file based on the authorization statement. By adopting the technical scheme, the purposes of automatically generating the SELinux authorization configuration file, improving the authorization efficiency and saving human resources are achieved.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of software development, and in particular to a method, device, electronic device and storage medium for generating an authorization configuration file. Background technique [0002] Due to the flexibility and good compatibility of the Android system, more and more terminals adopt the Android system, and a large number of Android applications also appear. Most of the applications may involve the user's privacy information. In order to ensure the security of the Android system, the kernel of the Android system integrates SELinux (Security-Enhance Linux, Security Enhancement System). The main role of SELinux is to minimize the resources accessible to service processes in the system. [0003] In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0004] At present, the SELinux authorization method of th...
