Projects
Mentor-Teacher for SANS Network Security Certification Conference
Taught three 11-week series of local mentoring sessions to teach students in technical network security material required for the SANS GIAC GSEC and GCIH Certification tracks. Sessions included hands-on usage of security tools, question and answer sessions and discussions of current and emerging security issues and defenses. Also developed new material security training on Web Application Security including hands-on labs for the SANS Institute LAMP (Linux, Apache, MySql and PHP) track.
Application and Network Security Consulting
Provided network, system and application security consulting for a wide variety of corporate projects from architecture and design consulting and site audit. Developed corporate security technical standards for Windows and Unix platforms. Performed security audits, vulnerability analysis and risk assessments for corporate data centers. Web Application security training and application security code inspections.
Remote Authenticated, Secure Mail Relay Service
Setup and administration of secure SMTP and POP3 services using sendmail, qpopper and openssl on a Unix platform for a remote office networks. All services included host and user authentication and encryption over SSL, as well as effective SPAM filtering with Spam-Assassin and Anti-Viral filtering with ClamAV.
Java Server Architecture, Security and Administration
Developed secure, scalable architecture for optimal price and performance. Deployed with security hardening, audits and monitoring, and secure remote access, using Apache, J2EE, JServ, openssl, ssh, vnc, perl, Nessus, Whiskers, and nmap.
Firewall setup and monitoring
Proposed and installed multiple open source Linux dual home proxy firewall for private school and office LAN, included log security monitoring, intrusion detection, and proxied web access with content filtering service. Software used included iptables, ipchains, apache, ssh, syslogd, sendmail.
XML Web Server secure HTTPS communication
Enabled secure browser to web server communication and XML web server to web server communication by integrating and configuring openSSL, X509 client and server certificates and Java Secure Sockets Extension (JSSE) for two different XML web server software products using the Apache+Jserv+mod_ssl web server on Solaris, Linux, FreeBSD, NT4.0 and Win2000 platforms.
Web Server Performance Analysis
Benchmarked and analyzed the performance of a client web site with competitive web sites, and proposed hosting and design changes that would bring a more than five fold increase in performance.
Software Methodology Training
Provided a series of in-house hands-on seminars on a full spectrum of software methodology, including object design technology, object modeling techniques, C++ programming, project management, requirements analysis with use-cases, and software configuration management with TeamWare. Also provided consulting services to analyzed current requirements for Software Configuration Management (SCM) tools and methodology in support of a SEI CMM (Capability Maturity Model) level 2 effort. Effort resulted in a detail requirements matrix, which was used in selecting SCM tools for several projects.
Embedded Web Server Administration Interface for Network Switch
Acting manager of a team of five software engineers to design, schedule, implement and maintain a web based network management system (NMS) for a fault tolerant switch. The NMS was implemented in current web technologies (HTML, DHTML, JavaScript and Java) through two generations of a fault tolerant network switch product. Proposed and supervised the design and implementation of cascading style sheets to decrease maintenance costs while increasing consistency in look and feel. Proposed, and help implement perl utilities which automated the build of the web servers file system and function control table.
Internet based Software Development and Administration
Designed and developed a C++ CORBA server with Orbix and Oracle, which provided document printing production services to a Java User Interface, developed using Visual Café. Developed perl scripts for the installation and configuration of the Apache web server, HTML and Java files. Also maintained the DNS zone and mail server for the project sub-domain.
Real Time Software Design and Development
Proposed several alternative design improvements for an RPC based lookup services used in an automated voice telephony assistance software subsystem. Implemented in a tight schedule a greater than five fold performance improvement in the service requests, which allowed the project to meet necessary real-time response requirements.
11/93 - 5/96 QUESTRA CONSULTING Rochester, NY
Project manager for the second largest on-site project, as well as project manager for the most successful to date in-house project. The three components of the out-source contract were awarded time-to-market bonuses for early delivery, of 1, 2 and 3 weeks respectively ahead of the contracted fix priced schedule which was only 11 weeks long. The project was the most profitable to date for the company in terms of the effective hourly rate, by exceeding its goal by 34%.
As the UNIX system expert for the Xerox DCS35 Multi-function printer, made a wide variety of recommendations and fixes for kernel and system level problems. Designed a UNIX System Vr3 device driver to emulate the BSD socket calls on VxWorks. The driver was designed for high performance by minimizing data movement, and while maximizing concurrency. Developed an advanced C++ seminar, and held two sessions of an intensive 4 day hands-on seminar, for a total of 27 consultants. The seminar covered all of the C++ language, including up-to-date ANSI innovations, the Standard Template Library (STL), as well as an introduction to current object oriented design methodologies.
5/91 - 11/93 ASEA BROWN BOVERI (ABB) PROCESS AUTOMATION Rochester, NY
Senior Software Engineer and technical project leader responsible for development of a central part of an object oriented management facility implemented in C++ to be used for process automation.
