ABSTRACT
A private network that carries sensitive data between local computers requires proper security measures to protect the privacy and integrity of the traffic. When such a network is connected to other networks, or when telephone access is allowed into that network, the remote terminals, phone lines, and other connections become extensions of that private network and must be secured accordingly. In addition, the private network must be secured from outside attacks that could cause loss of information, breakdowns in network integrity, or breaches in security.
