High Security Network Appliance – Essential Devices to Protect Your Data
Even as the internet network expanded its footprint and the government and private organizations created their own local area networks (LAN) and wide area networks (WAN), the concept of protecting the data that flows through these networks has assumed a great significance. There are people out there trying to lay their hands on the data by hacking into these networks. If you are in the profession of maintaining or owning any such network, you should be looking for a fail-safe security network appliance. But you will wish to gather as much background information on these gadgets involving advanced security technology as possible.
What Does the Appliance Do to the Network?
The concept behind the security appliance is to encrypt the data at the end where the data originates and then again decrypt the data and deliver to the recipient, all in real time. This way, the appliance has to be seen as a pair of devices acting as a tunnel, rather than individual pieces equipment. Now when you look at the appliance physically, it is usually a small box 5.5 inch in length and 3.5 inches in width and just above an inch in height and has a plastic casing and the provisions for the connectors. You can be rest assured that the cryptography of these devices are sound because of government validation requirements. The process of encryption of the data is clearly spelt out by the agency National Institute of Standards and Technology (NIST) and these are defined by the standard FIPS and the particular standard for the high security network appliance is FIPS 140-2.
Layout and Applications:
So if you look at the matrix involving a typical security network over which data is being transmitted, you will have the system which is a part of the LAN. Also, the security appliance falls in the middle and then the router which carries the data to the internet is accessible to the public. At the destination end, which is to receive the secure data, the router will be the first gateway and then the device, which is a part of the appliance to decrypt the data. Then it goes on to the system which will open and receive the data. The key aspect is the digital signage which is provided at both ends to access the data and then convey orders to encrypt and decrypt the data. As mentioned, large networks, like governments, hospitals and other entities would be using these high-tech devices.
