The Nonsecure Internet Protocol Router Network (NIPRNet)

The Nonsecure Internet Protocol Router Network (NIPRNet) is basically the same thing as the Secret Internet Protocol Router Network (SIPRNet), with the exception of what the two are used for. NIPRNet was created in the 1980s for the purpose of transmitting sensitive but unclassified information among “internal” users; it also allowed the “internal” users to access the regular Internet. NIPRNet is made up of Internet Protocol routers which are owned by the United States Department of Defense (DoD). Today NIPRNet is the largest private network in the world and is still growing.

 

The NIPRNet Verses the SIPRNet
As I said above NIPRNet and SIPRNet are basically the same, however there are some critical differences between the two. When you look at the design of both NIPRNet and SIPRNet they are both S be air gapped both from each other and from the Internet; however, both of them appear to have gateways which connect back to the Internet. As far as NIPRNet and SIPRNet actually being air gapped from each other, that is because one is made for transmitting classified information at the “Secure” level while the other is made for only transmitting information that is sensitive but unclassified. NIPRNet appears to simply be another private network that is hidden from the public; other networks like this would be Tor, I2P, and Freenet. Although all of these networks are similar to NIPRNet they are all actually quite different because NIPRNet is made up of routers that are all privately owned by the U.S. Department of Defense, which is very much unlike any of the other networks that I mentioned. Tor, I2P, and Freenet are all run by different routers that are all owned by different people and organizations, that is what makes these networks useful. NIPRNet is basically just like a very large organization’s private network because just like NIPRNet that organization will most likely own all of the routers that make up their network.

 

Evolution of NIPRNet
Just like the Internet has dramatically changed since the 1980s, so has NIPRNet. Today NIPRNet is pretty much a mess due to its desire to grow and expand. As mentioned above NIPRNet is the largest private network in the world. Just like any other traditional IP network, the more they grow the more you need to take into consideration the threat assessment model of the network. NIPRNet has grown so much in the past few decades, past the point of which the U.S. Department of Defense can monitor. Because of this the U.S. Department of Defense spent $10 million in 2010 to try to detect any unauthorized users and to better secure the network. The Pentagon also requested $2.3 billion in the 2012 budget to help improve the network security within the U.S. Department of Defense and to strengthen its ties with the United States Department of Homeland Security (DHS).
