Mr. Williams completed recommendations for GOSIP and POSIX migration for the National Defense University. This migration plan developed recommendations on implementing GOSIP, follow-on OSI standards, POSIX/FIPS-151, and future POSIX standards. Migration steps were detailed for migrations using RFC 1006 "ISO Transport on Top of TCP", POSIX Simple Network Services API, POSIX Network Services API, X/Window technology, and POSIX Windowing API.
At the National Defense University, Mr. Williams implemented gateway systems for LAN E-Mail to X.400 message transfer. Mr. Williams was the first to integrate interoperability between the NDU native Xerox Network with the Prototype Novell LAN for messaging. The implementation provided the only method of electronic communication between the Xerox network users and the Novell network users. This implementation eventually provided messaging relay and transfer services to the Novell users. This work was performed under a subcontract to Wang Corporation.
Mr. Williams and the was chosen to develop the implementation strategy for interoperation between the NDU Information Resources Management College (IRMC) prototype network and the NDU Xerox network. Mr. Williams structured the prototype network implementation so that normal operations were not disrupted. The project also required testing of interoperability between Apple Macintosh user end systems and PC-compatible end systems. The following was delivered:
Mr. Williams completed an analysis and design of a distributed messaging environment with a gateway to the MILNET/Defense Data Network. The analysis provided application scenarios and implementation guidelines for remote (asynchronous) WordPerfect Office (WPO) E-Mail transmission to activities supported by National Defense University. This analysis also addressed integration of NDU into the MILNET/Defense Data Network. Mr. Williams coordinated obtaining evaluation systems directly from vendors and resellers. These systems were implemented in a test bed environment. Mr. Williams assessed the viability of low cost asynchronous communications technology for the support of mobile NDU users and remote sites. Mr. Williams implemented gateway technology which allowed message transfer to and from remote laptop users, as well as remote WordPerfect Office asynchronous gateway sites.
Mr. Williams assessed interoperability issues connected with CISCO and Timeplex routers and delivered an interoperability test outline. Considerations included support for Point-to-Point protocol, Open Shortest Path First, Intermediate System-Intermediate System and static CLNP routing. This project was completed under an OST subcontract to American Systems Corporation.
For the Defense Information Systems Agency (DISA), Mr. Williams developed several alternatives and a recommended approach for implementing eight GOSIP/OSI LANs. Since these LANs would be interconnected by the current IPS - based MILNET, Mr. Williams had to develop a strategy using IPS to GOSIP/OSI application gateways. The project was completed under a subcontract to DIGICON Corporation. In the final report, Mr. Williams detailed both target and interim implementations. Different configurations were developed for LAN segments with and LAN segments without GOSIP/OSI routing capabilities.
For the Navy Integrated Interior Communications and Control (IC)2 Program, Mr. Williams provided an analysis and engineering architecture to illustrate TCP/IP suite and GOSIP/OSI suite coexistence and transition. This document provides a comprehensive overview of the potential benefits and difficulties that arise when implementing co-existence architectures. This task was in support of American Systems Corporation for (IC)2 efforts in developing network architectures for ship to shore, ship to ship and ship internal communications.
For (IC)2 program Mr. Williams conducted a Messaging and Directory Services Pilot (MDSP) in a phased approach. The purpose of this pilot is to validate advanced fleet messaging and directory services. The pilot technology also has improved interoperability, manageability, and will support future DoD messaging technology.
In the (IC)2 MDSP - Phase I, the program validated basic messaging, as well as messaging with graphical/audio/video attachments. Connection options between participating sites were also tested. This included X.400 P1 MTA-MTA communications via the RFC-1006 transport standard as well as SMTP message transfer via TCP/IP. An additional demonstration of the test technology was done at the InterOp Fall '92 show network (see below). This work was performed under a subcontract to American Systems Corporation.
MESSAGING AND DIRECTORY SERVICES PILOT - PHASE 1
In the Messaging and Directory Services Pilot - Phase 2, Mr. Williams augmented the Phase I activity with the implementation of support for wireless messaging user agents, and messaging services including e-mail via fax technology, remote file retrieval via e-mail, remote file fax via e-mail, receipt notification, non-repudiation, Electronic Data Interchange and the physical reproduction (printing) of messages on receipt.
MESSAGING AND DIRECTORY SERVICES PILOT (MESSAGING) - PHASE 2
In the Messaging and Directory Services Pilot - Phase 2, Mr. Williams implemented internetworked X.500 Directory System Agent and X.500 DAP and DSP over TCP/IP between participating systems. Mr. Williams established participation in the PSI/Internet White Pages Project pilot. This pilot also provides connectivity to the worldwide PARADISE X.500 directory pilot. Also, the functionality of X.500 based information retrieved to the desktop was explored.

RESULTS OF AN X.500 QUERY DISPLAYED ON A PC DESKTOP SYSTEM
Mr. Williams completed planning and implementation of the Bureau of Census internet firewall system. The system consisted of a ANS Interlock Application Gateway Firewall and router filter security. Mr. Williams presented lectures concerning policy and implementation considerations, designed and developed a test plan testing the integrity of the vendor implementation and conformance with requirements.
Mr. Williams also designed tests which confirmed IP router and ethernet switch vulnerability to IP spoofing and MAC spoofing. The MAC spoofing test results were crucial in the design and implementation of the secure system, and represent the only known published ethernet switch MAC spoofing test suite. The results were published in confidential Department of Commerce lectures to ensure security integrity. Mr. Williams also developed personnel role definitions for the enforcement of next generation ADP security, where Internet is readily accessible, and lectured extensively on considerations for the establishment of ADP and Telecommunications policies concerning Internet access, network load balancing, management, and physical security.
Mr. Williams is currently in the review and implemenation stage of an effort at the National Oceanic and Atmospheric Administration (NOAA). The NOAA efforts concern implementation and further review of NOAA security considerations. The planning and implementation of the NOAA internet firewall systems, network infrasstructure security and host system security. Initial efforts were performed by Lawrence Livermore National Labs (LLNL). Mr. Williams was called in to review systems for further vulnerabilities and implement security controls and review NOAA policy. LLNL also complimented Mr. Williams on his identification of MAC spoofing vulnerabilities in ethernet switching.. Other considerations are Application Gateway Firewall and router filter security. Mr. Williams presented lectures concerning policy and implementation considerations, designed and developed a review plan testing the integrity of the vendor implementation and conformance with NOAA and Dept. of Commerce security requirements.
Mr. Williams provides next generation ADP security, where Internet is readily accessible, and has lectured extensively on considerations for the establishment of ADP and Telecommunications policies concerning Internet access, network load balancing, management, and physical security, integrity and access control.
