Security in Networks

Abstract

In this report we describe what makes a network similar to and different from an application program or an operating system. In investigating networks, we have shown how the concepts of confidentiality, integrity, and availability apply in networked settings. At the same time, we have also added that the basic notions of identification and authentication, access control, accountability, and assurance are the basis for network security, just as they have been in other settings. Networking is growing and changing perhaps even faster than other computing disciplines. Consequently, this report is unlikely to present you with the most current technology, the latest attack, or the newest defense mechanism.
