Embodiment Construction

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0035] First, explain the related technologies of SeLinux. Generally speaking, SeLinux will make the operation of the system in a restricted state. Any specific access operation needs to be authorized before it can be allowed. The operations that the system can perform are clear. least privilege set. If the system is transplanted with SeLinux, all illegal operations of the system will be recorded in the form of logs and stored in the special dire...

Abstract

The invention discloses a terminal and a method for improving system safety. The terminal comprises a configuration module and a storage module, wherein the configuration module is used for configuring specific domains to a plurality of users, the users comprise the safe users and the common users, the specific domain of each safe user is a safe domain, and the specific domain of each common user is a common domain; the storage module is used for storing application data commonly used by the users in the specific domains corresponding to the users. By means of the technical scheme, the terminal and the method for improving the system safety solve the problem that an existing safe system cannot relate to multi-user safety solution schemes. By combining a multi-user mechanism and a Seandroid mechanism, a safety solution scheme is provided for the system, application can process the data in the specific domains of the users, and therefore the effect of improving the system safety is achieved, and the single terminal can have safe access to the data in the specific domains.

Description

technical field [0001] The invention relates to the field of system security, in particular to a terminal and a method for improving system security. Background technique [0002] SELinux (Security Enhanced Linux) was originally started by the NSA (National Security Agency) and added to a set of core components and user tools in the Linux system, allowing applications to run on the minimum permissions they need. [0003] Currently, the security system of the android terminal is mainly Samsung's Knox technology, which mainly combines seandroid and multiple applications to set the security domain. Knox puts certain secure apks under a separate directory, and then uses seandroid to restrict individual permissions on these apks, so that apks in other domains cannot access the data under this domain. However, under the current security system, there is no overall security solution directly involved, and it is not suitable for multi-user situations. When Knox technology came out,...
