The value of data is based on the perspective of the consumer and their objective. If we're talking data in support of warfighter data then the data will be stored where the warfighter can get to it with the least amount of disruption to their operation. If we're talking other data that supports the warfighter then that data might reside at any nunber of places. Additionally, there must be a consideration for raw data vs. product data; data that have been analyzed and produced as actionable. In any case, data for use by systems or people should be protected using a layered approach. At the information layer this means applying security directly to the information, at the infrastruture level this means protecting the information and how its transmitted from one point to another, and at the application layer it means making sure that those objective that access the data have the approriate level of credentials. Its also important to understand that protecting the data is not the only means for ensuring appropriate access. Advesaries will also attack our connections; not connection, no access to the data. So, the layed defense approach not only proetects the information but also protects the conntection between the consumer and the produces. When determining how best to apply Layered defense it is a good practice to use a profile approach. There are 3 profiles when using a layered defense, the Enablement Profile, the Defensive Profile, and Offensive Profile. If interested I can provide more details on what these are and how to apply them when developing a layered strategy.

The original ARPANET is now the Internet. It no longer exists. The Department of Defense maintains their own, secure network similat to the Internet for defense purposes today.
It is the Intrusion Prevention System that checks the network traffic and tries to provide a defense against malware.
Web server Most organizations place their web servers in a perimeter network. A perimeter network is a special area located between the internal network's line of defense and the internet. This area allows you to place devices that are to be accessible to the public, while at the same time, protecting the private network from the public. Devices that are normally located in such networks include public web servers, e-mail servers, and FTP servers
It was split in layers to separate different function in different blocks. In such way it's easier to maintain code and support as well as use it. And if it happens that one layer has problem you do not have to fix other layers. In programming it's called abstraction and encapsulation.

A layered network, or a network layer, is the set up of how data is sent over a network. Each layer has it's own responsibility by either capturing the data or routing it to a computer on the network.
Servicemembers Legal Defense Network was created in 1993.
No.
Principles are not advantages or disadvantages of the layered approach, principles are behind the layered approachPrinciples:Data transmission error free.Minimum time for route discovery.Communication between layers through primitives.Congestion control for minimum delays and retransmission.Minimum effort in replacing new layer in the existing network layers.
India became increasingly valuable to the British after they establish a railroad network there. India became increasingly valuable to the British after they establish a railroad network there.
