The U.S. National Institute of Standards and Technology (NIST) identified that approximately 1.8 million cybersecurity positions were vacant in 2021 because of a lack of professionals with the required skill sets and who remained in their jobs long enough to contribute to their organizations' cybersecurity needs. Also shown was the rising global need to develop a sustainable pipeline of cybersecurity professionals. Organizations of all types were increasingly dependent on information technology and internet-connected devices, subject to numerous and frequent threats to their IT systems. University graduates with the required cybersecurity skills were not available in sufficient numbers to meet the cybersecurity needs of organizations. As a result, the cybersecurity work of organizations was hampered. An evidence-based approach was used to examine the gap between the need for university-prepared cybersecurity professionals and the availability of skilled cybersecurity professionals who remained in their positions. Using the CIMO method, the research question for this dissertation was: What are the best practices for developing university graduates for the global cybersecurity workforce? A systematic review of the literature, using thematic analysis, was conducted to investigate how managers could deal with this cybersecurity workforce deficit. The systematic review findings based on coding, supported by 28 relevant studies, identified three main findings/recommendations: (a) implementing an organizational learning environment using organizational learning theory (OLT), demonstrated by an apprenticeship strategy program; (b) the need for a global cybersecurity management skill set supported by inhouse skills training institutes; and (c) the need for an enduring cybersecurity pipeline, exemplified by an internal promotion strategy. Risks to implementation of these recommendations also is provided. [The dissertation citations contained here are published with the permission of ProQuest LLC.
