Your efforts will directly contribute to safeguarding FEMA's mission-critical systems and data. The Senior ISSO will serve as the single point of contact for the Cybersecurity Division on all systems security matters, leading cybersecurity engineering efforts for assigned Program Management Organizations with direct support to the Compliance Branch Lead.

The Senior ISSO will ensure proper access controls are implemented for both system access and physical access to data processing facilities, track and suggest technologies, processes, and practices designed to protect networks, devices, programs, and data from malicious attack, damage, or unauthorized access, and research and maintain proficiency in tools, techniques, countermeasures, and trends in computer and network vulnerabilities, data hiding, and network and device security and encryption.
