Abstract

The invention provides a security management method applied to mobile terminals. The security management method comprises the following steps: when the fact that an assigned file is implanted into a system is monitored, a prompt message is displayed to prompt a user whether to delete the assigned file or not, wherein the assigned file is used for helping an application without a superuser permission obtain the superuser permission; a deletion instruction triggered by the user according to the prompt message is acquired; the assigned file is deleted according to the deletion instruction. Meanwhile, the invention provides a security management device. According to the security management method and device, the fact that a malicious application performs malicious acts by obtaining the superuser permission and endangers system security can be effectively prevented.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a safety management method and device. Background technique [0002] The Android (Android) operating system is one of the mainstream operating systems developed based on Linux and widely used in mobile terminals. Since Linux is a multi-user coexisting operating system, in order to prevent some users from performing malicious or wrong operations on the system, Android classifies and restricts user permissions, and different users are granted different permissions. Among them, Root (super user) authority has the highest authority of the entire system. Users who have obtained Root authority have absolute control authority of the entire system. They can perform operations in the system including starting or stopping a process, adding or disabling hardware, and deleting disk files. and other operations that may endanger system security. [0003] However, it is difficult for ordina...
