Software automatic protection system and security card based on firmware

Abstract

The invention discloses a firmware-based software automatic protective system and a security card. A guidance module in the system modifies the vector of an interrupt INT13, so that the interrupt INT13 points to an implantation module; when the interrupt INT13 is triggered, the implantation module starts to run, and a real mode implanted part modifies the long jump instruction of the computer operating system in computer memory, so that the long jump instruction points to the implanted part under a protected mode; when the computer operating system runs under the protected mode, the implanted part under the protected mode runs, the implanted part under the protected mode scans the computer memory space for finding and modifying a driving link list in the computer operating system, so that an automatic software installation module is linked to the driving link list; the automatic software installation module is operated by the computer operating system; and the automatic software installation module reads and runs a safe guarding module, so that safe guarding is performed on the computer. The invention ensures that the security software is installed automatically, thereby ensuring that the security software can not be stopped or uninstalled illegally, and the invention is applicable to various operating systems.

Description

technical field [0001] The invention relates to a safety card and a software automatic protection system to realize the safety protection of the computer. Background technique [0002] At present, the known computer data security protection systems are implemented by software, which is low in cost, flexible, and easy to install, but if the system is reinstalled, the security protection software needs to be reinstalled, which is inconvenient to use, and some Users will use "formatting" or "image recovery" to remove the protection software, and use "mirror recovery" to easily restore the security software to cope with the inspection; some Trojan horses and viruses will also stop the protection process . Therefore, the reliability of the software solution is low. [0003] At present, the hardware security solutions on the market have single functions and do not have the function of installing any software. For example, the hard disk recovery card can only restore the hard dis...

Problems solved by technology

[0005] The patent application "a method of embedding the kernel driver in the Windows operating system by using a PCI card" (patent application number: 200710119810.9) proposes a method of modifying the int13h interrupt, modifying the windows registry in the memory, and implanting the kernel driver. The method can only be applied to the windows operating system and is not universal, and there is no introduction to the automatic installation of security software in the application, and it cannot handle the behavior of illegally stopping and uninstalling security software
