Abstract

The invention provides a method and device for guaranteeing the system security. The method includes the steps that a dynamic-loadable kernel module (LKM) is set in a Linux system of an EPG device, and preset security configuration files are loaded in the LKM; when file operation is carried out, whether the file operation is legal or not is detected according to the security configuration files; under the condition that the file operation is legal, the file operation is carried out, and if the file operation is illegal, the file operation is refused to be carried out. By means of the method and device for guaranteeing the system security in the technical scheme, the problem that the security level of the EPG device in the related technology is low is solved, and the security of the EPG device is greatly improved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method and device for ensuring system security. Background technique [0002] Internet Protocol TV or Interactive Personal TV (IPTV for short) uses TVs, computers and mobile devices as display terminals, and connects set-top boxes, computers or mobile devices to the Internet. Through the Internet, especially Broadband network provides various real-time and non-real-time multimedia services to various users such as TV, PC, and mobile terminals. [0003] Some core devices in the IPTV system are deployed inside the firewall, but the Electronic Program Guide (EPG) equipment that provides services to users must be deployed outside the firewall, which is often attacked by hackers, resulting in program tampering Or it is deleted, which directly leads to abnormal IPTV services and cannot provide services for users. [0004] The reinforcement strategies in related technologies are a...
