Brown, C. D.

TCP/IP is the name commonly used to refer to a suite of networking protocols that was originally developed under the auspices of the Department of Defense for use on the Arpanet. These protocols are in wide use today on a large number of networks and have become accepted as a de facto industry standard. The Transmission Control Protocol (TCP) occupies the transport layer in the protocol suite, and the Internet Protocol (IP) occupies the network layer. In addition, there are a wide variety of other protocols in the DDN protocol suite. For example, the Unreliable Datagram Protocol (UDP) is alternative transport layer protocol that provides a simple unreliable datagram (packet) delivery service and uses the services of IP. The File Transport Protocol (FTP) and TELNET are application layer protocols that provide for file transfers and interactive logins, respectively, across a network using the services of TCP and IP. In this paper, we will discuss security labeling in a TCP/IP network with emphasis on the attempts to standardize labels at the IP layer; however, we will also discuss some of the issues relating to application protocols and privileged server processes in host computer systems. 4 refs., 1 fig.
