This chapter presents the outcome of two empirical research studies that assess the implementation and validation of the cybersecurity audit model (CSAM), designed as a multiple-case study in two different Canadian higher education institution. CSAM can be applied for undertaking cybersecurity audits in any organization or nation state in order to evaluate and measure the cybersecurity assurance, maturity, and cyber readiness. The architecture of CSAM is explained in central sections. CSAM has been examined, implemented, and established under three research scenarios: (1) cybersecurity audit of all model domains, (2) cybersecurity audit of numerous domains, and (3) a single cybersecurity domain audit. The chapter concludes by showing how the implementation of the model permits one to report relevant information for future decision making in order to correct cybersecurity weaknesses or to improve cybersecurity domains and controls; thus, the model can be implemented and sufficiently tested at any organization.
