This product is WISELY the latest foreign company builds the physical isolation technology, and independent research and development of a physical separation of network security for network security products, the product from the Zhuhai Special Economic Zone Limited Manufacturing WISELY.
On the physical isolation
Today, we have more and more realize that we must join the network, whether it is Internet, www, email, etc., "join" our benefit, when you have entered the Internet age, you will be very difficult to leavenetwork, but at the same time, we are also subject to increasingly serious security threats from the network, such as network data theft, hacker attacks, virus release, or even a leak within the system.
Although we are broadly to a variety of complex software technologies such as firewalls, proxy servers, hit the detector, access control mechanisms, but these techniques are based on the protection of software is a logical mechanism, which for the logical entity (ie,hackers or internal users) that is likely to be manipulated, that is the extreme complexity of these technologies and the limited nature of these online analytical techniques can not provide some of the organizations (such as troops, military, government, finance, research institutes, telecommunications, and enterprise) proposed a high degree of data security requirements.
Based on the position of security officials, "If there is no physical connection with the network, network security threats has been a real constraint," and of "the international networking of computer information system security regulations" in Article VI, "involving state secretscomputer information systems, not directly or indirectly, with the Internet or other public information networks, must be physically isolated, "Based on the above policies and regulations, we developed this new network security technology - Network Security Physicalisolation technology and technology-enabled products to achieve this - WISELY Principal network security isolation card.
Technical Principle
Network security functionality that is, isolation card will be a physical means Virtual PC for two computer workstations to achieve the dual status, either in a safe condition, but also in the public state, two states are completely isolated, so that aworkstations can be connected in a fully safe condition inside and outside the network.Network security is actually a separate card in the PC is set to the lowest physical layer, through the side of the IDE bus on the card association board, on the other side connected IDE hard drives, internal and external network connection required to pass the network security isolation card, PC hard driveis physically separated into two regions, the IDE bus physical layer, in the firmware to control disk access, at any time, the data lead only to a partition.
Figure 1
In a safe state, the host can only use the internal hard disk and network connection security zone, at which point the external network (eg Internet) connection is broken, and the hard drive access in public areas are closed.
In the public state, the host can only use the hard disk of the public area, you can link with external networks, but this time with the internal network is disconnected, and the hard security zone is to be closed.
Easy conversion
When the two state transition, the operating system by clicking on the mouse to switch to enter into a warm boot process, switch, the system restarted by the hardware reset signal, so that, PC's memory, all data is eliminated, the two states, which areis independent of the operating system and is independent of import, while the two hard disk partitions will not be activated.
Data exchange
In order to guarantee security, the two partitions can not directly exchange data, but users can be one of our unique design, easy to secure data exchange, that is, other than in the two partitions, network security isolation on the hard drive set a function on anotherarea, functional area in the PC in a different state transition, that is two states, the functional areas are expressed as the D drive disk, each partition can function as a transition zone area to exchange data.Of course, according to user needs, but also to create a one-way secure channel, that data only from public areas transferred to safe areas, but can not reverse the transfer, thus ensuring the safe area of data security.
Zone control
Based on security threats from both internal and external relations, that is, in addition to external hackers, viruses released outside the system within the intentional or unintentional disclosure, but also the need to prevent the threat.Therefore, the network security isolation card can be read-only control of the security zone, you can disable the internal users to floppy, CD-ROM copy of data or altered data on the safety zone.
The wide application
Since network security is to control the primary IDE isolation card bus, in the bottom of PC-based hardware, so broad support for almost all Pentium and Pentium-compatible chips.
As the network security isolation card is completely independent of the operating system and, therefore, supports almost all major operating systems.Network security isolation card on the network technology and protocol is completely transparent, so the main agreement on the current widespread support, such as Ethernet, Fast Ethernet, token ring network, optical fiber, ATM, ISDN, ADSL.
Installation and use
The installation of network security is not complicated isolation card, in general, does not need to change the user the original network structure, installation of the skill of an ordinary network card installed very demanding level.Installation of network security isolation card, under normal circumstances, do not have to worry about losing data because, left to copy the hard drive data.Users can only accept the simple use of the training, there is no future maintenance issues.
Scope with the argument
Based on national requirements for confidentiality, WISELY physical isolation of network security technology, is fully consistent with this.Therefore, this technology is applicable to almost all both very strict data security, while expectations of the various agencies connected to the Internet, such as government agencies, military institutions, finance, telecommunications, research institutions and large enterprises and more.WISELY "network security isolation card" and "network security isolation hub" has been through the national Ministry of Public Security and National Information Security Evaluation Certification Center certification authority and other countries, and already have the relevant certificate.
