Abstract

The present invention provides a method and device for applying SELinux security policies in multiple systems, which are applied in a terminal equipment operating environment including a main control system and at least one subsystem. The method includes: when starting the main control system, applying SELinux Import the security policy basic file into the system kernel, and load the SELinux policy basic file in the system kernel; when starting at least one subsystem, import the SELinux security policy files corresponding to each subsystem into the system kernel, and load SELinux in the system kernel respectively Security policy file. The technical scheme of the invention solves the problem of how to apply SELinux security policies in multiple systems. The solution provided by the embodiment of the present invention strengthens the security of multiple systems, thereby creating a good terminal device experience environment for users.

Description

technical field [0001] The present invention relates to the technical field of terminal equipment. Specifically, the present invention relates to a method for applying SELinux security policies in multiple systems and a device for applying SELinux security policies in multiple systems. Background technique [0002] SELinux is a Mandatory Access Control (MAC) security system based on the Domain-Type model. It is designed by the National Security Agency (NSA) and designed to put security modules into the system kernel. In the form of the system, SELinux also includes corresponding security policies, and the upper-layer system can perform corresponding safe operation operations based on the security policies. In addition, some security-related applications can also be patched with SELinux-related patches to improve the security level of security-related applications. In an ordinary Linux system, any application has complete control over its resources. If an application stores ...
