Description: Computer and network security is a complex problem that is not solely restricted to classified computer systems and networks. Accelerating trends in networking and the emphasis on open interoperable networks has left many unclassified systems vulnerable to a wide variety of attacks. Computer and network professionals must understand the scope of  security, recognize the need for security even in unclassified systems, and then take appropriate action to protect their systems. Transmission of static passwords in plaintext  over the Internet is one of the most widely publicized network vulnerabilities. Cue-time password mechanisms (such as S-Key) or other secure network access mechanisms (such as Kerberos) have been recommended to improve access security for computer systems connected to the Internet. This thesis examines many of the issues that must be addressed when assessing the need for computer and network security. This work provides the results  of a site security survey for the unclassified IP/ATM LAN in the Systems Technology Lab  (STL) at the Naval Postgraduate School (NPS). These results highlight new security vulnerabilities and strengths that occur when standard Internet Protocol (P) local-area networks (LANs) are internetworked with Asynchronous Transfer Mode (ATM)      wide-area networks (WANs).  Finally, we examine the feasibility of using the Kerberos authentication protocol for remote plaintext password protection and provide  recommendations for additional work.
