• Designed, built, tested and deployed a remote management system to allow administrators to control and monitor high assurance Cross Domain Solutions from around the world. This lowers the cost of management by removing the need for multiple administrators to be deployed to everywhere the CDS systems are installed possibly in high risk areas. Helped design and implement a cross domain logging mechanism allowing remote systems and networking equipment to safely and securely transmit logs across security boundaries and consolidate logs from multiple domains to one system. • Worked as part of the HP NetTop development team helping debug, develop and secure the NetTop product. Also supported onsite customers with new deployments of HP NetTop, helping solve problems such as hardware compatibility, operating system upgrades, kernel bugs, software configurations, custom programming and networking issues.• Modified an existing VPN solution to fully harden and minimize the operating system as well as reducing the disk space used by 85% and memory required by 50%. Hardened the system with a custom SELinux policy and updated system to fully support Suite B encryption algorithms, stronger firewall rules and active connection monitoring to ensure stable and secure connections.• Responsible for direct support of the HP NetTop CT&E effort. Assisted CT&E teams to install a custom configuration of NetTop, answering all questions and providing input and analysis of the base operating system as well as the security features of the system as well as mitigating findings resulting from testing. Performed ST&E of the solution at customer site.• Assisted government CT&E and penetration testing teams in analysis of different cross domain solutions ranging from high speed transfer solutions to mobile devices. Performed white box testing, source code analysis, SELinux policy analysis, system design review, and assisted presenting the findings to the CDTAB.

• Team and Technical lead of the security team for the High Assurance Platform, a system designed to allow multiple Virtual Machines to run a system on different security networks ranging from top secret to unclassified. Primary responsibilities included SELinux policy development, addressing CT&E findings, and general platform security. • Taught introductory and advanced SELinux policy development courses to classes ranging in size from 6 to 25 students not familiar with SELinux and/or computer security.• Assisted CT&E teams in doing SELinux policy analysis of the various high security systems. This work included identifying possible vulnerabilities in the system and assessing if the system met its security objectives. • Contributed to the design and integration the Coalition Secure Management and Operations System. Created a system design to meet DCID 6/3 and DODI 8500.2 security requirements. Worked with a team of over 30 system designers, security engineers and Command and Control experts from the UK, Singapore, Canada and Australia to implement a common system for all coalition partners to use.• Created a fully customized SELinux policy for a Cross Domain Solution focused on real time chat across multiple security enclaves. Using both role based access control and type enforcement, created a policy with an emphasis on least privilege. Also contributed to system design, implementation and testing.• Team and Technical lead of 8 developers and system engineers to create a extensible filtering framework enabling the use of custom and off-the-shelf filter mechanisms. Rapidly designed and developed system prototype in 10 weeks far exceeding customer expectations and successfully demonstrated this prototype to many VIPs.
