An Explanatory Review on Cybersecurity Capability Maturity Models

Cybersecurity is growing exponentially day by day in both the public and private sectors. This growth also comes with a new and dynamic cyber-threats risk that causes both sectors' performance to halt. These sectors must update their cybersecurity measures and must understand the capability and maturity of their organization's cybersecurity preparedness. Cybersecurity maturity models are widely used to measure how ready an organization is when it comes to cybersecurity. The main aim of this article is to conduct a comprehensive review of the current cybersecurity capability maturity models using a systematic review of published articles from 2011 to 2019. A comparative study was conducted based on Halvorsen and Conradi's taxonomy. The review indicated almost all the cybersecurity maturity model consists of similar elements like maturity levels and processes but significantly lacks the validation process, it was observed each of the models were predominantly designed for a specific purpose and also for different organization size and application domain.
