Embodiment 1

[0072] In Embodiment 1 of the present invention, a method for dynamically updating an access control policy is provided. The schematic flow chart of the method is as follows figure 2 shown, including the following steps:

[0073] S201: After the master control system detects that the application scenario changes, it obtains the access control policy corresponding to the current application scenario from the cloud server.

[0074] The application scenario includes at least one of the following: time, geographic location, and access permission update notification issued by the cloud server.

[0075] For example, when the main control system detects that the current time has changed from on-off hours to off-off hours, it obtains the access control policy corresponding to off-off hours from the cloud server.

[0076] When the main control system detects that the current geographic location has changed from a classified geographic location to a non-confidential geographic locatio...

Embodiment 2

[0122] In Embodiment 2 of the present invention, a method for dynamically updating an access control policy is provided. The schematic flow chart of the method is as follows Figure 4 shown, including the following steps:

[0123] S401: After the container system detects that the application scenario changes, it obtains the access control policy corresponding to the current application scenario from the cloud server.

[0124] The application scenario includes at least one of the following: time, geographic location, and access permission update notification issued by the cloud server.

[0125] For example, when the container system detects that the current time has changed from working hours to off-working hours, it obtains the access control policy corresponding to off-working hours from the cloud server.

[0126] When the container system detects that the current geographic location has changed from a confidential geographic location to a non-confidential geographic locatio...

Abstract

Embodiments of the present invention provide a method and device for dynamically updating access control policies. The method includes: after the main control system detects that the application scene has changed, obtains the access control policy corresponding to the current application scene from the cloud server; Verify the validity of the access control policy; when the legality verification result is legal, the main control system sends the obtained access control policy to the kernel; after receiving the access control policy, the The access control policy is updated so that the kernel controls access to the container system according to the access control policy corresponding to the current application scenario. The embodiment of the present invention can realize the dynamic update of the access control policy on the basis of ensuring the security of the main control system, the kernel and the access control policy; it not only protects the confidential information in the terminal device, but also can dynamically update the access control policy conveniently .

Description

technical field [0001] The present invention relates to the technical field of terminals, in particular, the present invention relates to a method and device for dynamically updating an access control policy. Background technique [0002] With the development of society and the progress of science and technology, terminal devices such as smart phones, tablet computers and e-readers are widely popularized. [0003] An operating system is usually installed in the terminal device, and multiple applications are usually installed in the operating system. Multiple applications with multiple functions have met the needs of users. [0004] Take the Linux operating system as an example. In the operating system, in order to ensure the security of the system, the Linux operating system can use SElinux (Security-Enhanced Linux, Security Enhanced Linux) technology to implement the policy that different applications have different access rights to resources. . For example, whether to a...
