Network Security | Know It All | Complete Guide

[TheStrength]

Computer networks are typically a shared resource used by many applications representing different interests. The Internet is particularly widely shared, being used by competing businesses, mutually antagonistic governments, and opportunistic criminals. Unless security measures are taken, a network conversation or a distributed application may be compromised by an adversary. Consider some threats to secure use of, for example, the World Wide Web. Suppose you are a customer using a credit card to order an item from a website. An obvious threat is that an adversary would eavesdrop on your network communication, reading your messages to obtain your credit card information. How might that eavesdropping be accomplished? It is trivial on a broadcast network such as an Ethernet, where any node can be confi gured to receive all the message traffi c on that network. Wireless communication can be monitored without any physical connection. More elaborate approaches include wiretapping and planting spy software on any of the chain of nodes involved. Only in the most extreme cases, such as national security, are serious measures taken to prevent such monitoring, and the Internet is not one of those cases. It is possible and practical, however, to encrypt messages so as to prevent an adversary from understanding the message contents. A protocol that does so is said to provide confi dentiality. Taking the concept a step further, concealing the quantity or destination of communication is called traffi c confi dentiality—because merely knowing how much communication is going where can be useful to an adversary in some situations.

Even with confi dentiality there still remain threats for the website customer…
