The TCP/IP protocols, the basis for today's Internet, lack even the most basic mechanisms for security,
such as authentication or encryption. As usage of the Internet and TCP/IP protocols increases, their
lack of built-in security has become more and more problematic. This paper describes a variety of basic
flaws in TCP/IP protocols and their implementations, and discusses solutions and work-arounds to
these problems. Also covered is the new IPv6, the next-generation Internet protocol that, among other
goals, seeks to fix many of the current flaws in the current Internet IPv4 protocol. Security in protocols
and applications not essential to TCP/IP (such as HTTP, FTP, and SMTP) are not discussed in this
paper
