There is a general perception that there is a shortage of cybersecurity professionals within the United States, and a particular shortage of these professionals within the federal government, working on national security as well as intelligence. Shortages of this nature complicate securing the nation’s networks and may leave the United States ill-prepared to carry out conflict in cyberspace. RAND examined the current status of the labor market for cybersecurity professionals—with an emphasis on their being employed to defend the United States. This effort was in three parts: first, a review of the literature; second, interviews with managers and educators of cybersecurity professionals, supplemented by reportage; and third, an examination of the economic literature about labor markets. RAND also disaggregated the broad definition of cybersecurity professionals to unearth skills differentiation as relevant to this study. In general, we support the use of market forces (and preexisting government programs) to address the strong demand for cybersecurity professionals in longer run. Increases in educational opportunities and compensation packages will draw more workers into the profession over time. Cybersecurity professionals take time to reach their potential; drastic steps taken today to increase their quantity and quality would not bear fruit for another five to ten years. By then, the current concern over cybersecurity could easily abate, driven by new technology and more secure architectures. Pushing too many people into the profession now could leave an overabundance of highly trained and narrowly skilled individuals who could better be serving national needs in other vocations.
