Extensive experience with Intelligence Community (IC), Department of Defense (DoD), Defense Information Systems Agency (DISA), NAVINTEL Cybersecurity, Fleet Cyber Command (FLTCYBERCOM), and DoDIIS processes, tools, systems, reporting mechanisms, and requirements supporting Assessment and Authorization (A&A).
Software development experience using Java, C, C++, or other programming or scripting languages, including experience designing and developing host based and network based scanning tools.
Experience with Security Content Automation Protocol (SCAP) based tools and specifications.
Experience installing, configuring, testing, deploying, operating, and maintaining enterprise network based scanning and reporting tools such as Trellix/ESS, ACAS, RedSeal, Evaluate STIG, SteelCloud ConfigOS, and STIG Manager.
