Description
Technical field
The present invention relates to computer field, especially a kind of dual net physical shielding system.
Background technique
It is on the rise with the rapid development of Internet, computer network is divulged a secret, confidential data is lost in relating computer
Problem, oneself becomes the public service enabled in Party and government offices, army, Defence business, scientific research institution and citizen's basic information collection
The problem that mechanism has a headache very much.According to the relevant information, computer network and computer lose data in current security work
Caused by the leakage of a state or party secret, oneself accounts for divulging a secret 70% or more of sum, and in increasing to become year by year.
To prevent computer network dual net physical isolation scheme of divulging a secret from arising, and be directed to existing dual net physical every
From being usually an interconnecting device for passing through PCIE for scheme, using double netcard and double hard disks, but after switching system, make
Memory and CPU or one, after switching system, if there is data remanence to will lead to divulge a secret and happen in memory.
Further, when network 1 and hard disk 1 are switched to network 2 and hard disk 2, computer is shutdown caused by abnormal power-down, interior
There are also cachings not to discharge in depositing, and network 2 and hard disk 2 have been started up, can be in network 1 and hard disk 1 by special means
Remaining data are taken out from the caching of memory.
