A method of dynamically isolating computer systems

Abstract

The invention provides a method for dynamically isolating computer system. An isolating system is established via a virtual environment to isolate a peripheral and a host, so that the virus inflection risk for resources in the host can be reduced. The isolating system comprises a host interaction unit, an isolating unit and a peripheral interaction unit, wherein the host interaction unit is used for isolating resource interactions between the system and the host and monitoring the isolating unit, the isolating unit is used for analyzing and reporting safeness of interactive data between the host and the peripheral, and the peripheral interaction unit is used for reconstructing a peripheral lead module and preferentially submitting data to the isolating system after the peripheral is loaded. The isolating process includes that an isolating system is started when a new peripheral such as a virtual machine is loaded, isolating operations are implemented to the peripheral, network and a mobile hard disk drive by the isolating system when a universal serial bus flash disk accesses, the isolating system is eliminated directly when a safety problem is found, and a new isolating system is created to guarantee the safeties of the host system and host resources.

Description

technical field [0001] The invention relates to the field of computer security, in particular to an active isolated computer system high security architecture. technical background [0002] At present, the U disk virus is rampant, invading countless personal computers, and making the majority of computer users troubled. [0003] For this reason, most security software manufacturers provide U disk killing tools on their respective products, that is, when loading a U disk, create an antorun.inf folder in the root directory of the U disk to prevent the U disk from Start by itself to avoid viruses generated by automatic loading. [0004] The current solutions of computer manufacturers all need the support of U disk, that is, the U disk must be started with autorun.inf, and this method can only defend against this self-starting virus. , digital camera, SD card, etc.) are difficult to fully antivirus. At the same time, when there are viruses in the data stored in the peripheral...

[0004] The current solutions of computer manufacturers all need the support of U disk, that is, the U disk must be started with autorun.inf, and this method can only defend against this self-starting virus. , digital camera, SD card, etc.)

At the same time, when there are viruses in the data stored in the peripherals, these viruses will still spread to the host. This is because the current computer manufacturers mainly adopt the anti-virus method of first infecting and then killing. This method must be used by some Trojan horse viruses , it is difficult to completely remove these viruses when you are infected
