Information Assurance

Abstract

The TCP/IP protocol is becoming the world standard for network and computer communications. The number of TCP/IP applications on the Internet and in corporate networks is continually growing, with a resulting increase in network vulnerability. When data communications security is discussed in this text, it refers to communications security for the TCP/IP protocol and to the security mechanisms implemented at the different layers of the TCP/IP stack protocol. This chapter also describes, in a general way, which security mechanisms are used for specific security services.
