This bill establishes a new DHS Cybersecurity On-the-Job Training Program within the Department of Homeland Security to enhance its internal cybersecurity workforce. The program's primary goal is to voluntarily train existing DHS employees who are not currently in cybersecurity roles, preparing them for cybersecurity-related work within the Department. This initiative will be led by the Director, in consultation with the Under Secretary for Management, to ensure effective implementation and oversight. The Director is tasked with several key responsibilities for the program's success. These include developing a comprehensive curriculum, potentially incorporating existing resources like the Federal Cyber Defense Skilling Academy, and ensuring consistency with the National Initiative for Cybersecurity Education Framework. The Director must also establish participation criteria, make cybersecurity training available to DHS employees, and potentially to other federal employees. Furthermore, the Director is required to submit annual reports for seven years detailing participation numbers, positions filled by trained employees, and metrics used to measure program success. The Under Secretary for Management also plays a crucial role in supporting the program. Their duties include submitting annual reports to the Secretary on cybersecurity position vacancies across the Department for seven years. They are also responsible for supporting the Director's efforts to identify and recruit employees for the program, implementing policies like continuing service agreements to encourage participation, and conducting outreach to program graduates regarding cybersecurity job opportunities within DHS.
