Mobile terminal, security defense device thereof and security defense method thereof

Abstract

The invention provides a mobile terminal, a security defense device thereof and a security defense method thereof. The security defense device comprises a storage module, a start-up management module and a defense module. The storage module is arranged in a root file system of the mobile terminal and used for storing an executable file in the defense module. The start-up management module is used for acquiring and operating the executable file according to a configuration file in the mobile terminal during starting-up of the mobile terminal. The defense module is used for generating a permanent defense progress according to the operating executable file. The defense progress is used for monitoring abnormal behaviors of the mobile terminal and taking active defense according to the abnormal behaviors. By the security defense device, incapability of uninstalling of a safety protection program, and permanent memory operation and automatic start-up management of a safety protection progress are realized, all-around monitoring and protection as well as self-repairing, performed by the safety protection progress, on an application layer and a service layer of an operating system of the mobile terminal are guaranteed, and safety protection of the operating system can be effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of mobile equipment manufacturing, in particular to a security defense device and method for a mobile terminal and a mobile terminal. Background technique [0002] With the large-scale popularization of mobile terminals (such as mobile phones, tablet computers, etc.), many viruses, Trojan horses, and malicious attack programs have begun to invade the operating systems of mobile terminals, especially Android operating systems that can be rooted by third-party applications ( The only superuser) authority in the operating system, which can modify almost any data in the operating system. Once the operating system of the mobile terminal is cracked by the attacker, the attacker can obtain a large amount of private and sensitive information of the user, which will cause great harm to the user and bring a severe test to the security of the user's private and sensitive information.
