Multi-Factor Authentication Modeling using Petri Nets: Review

As the cyber security field enhanced within years, threats and vulnerabilities have increased massively among the world by each second. Such risks have resulted an immediate action by businesses and organization by implementing and deploying different technologies in order to secure and defend such attacks that may cause problematic actions by hackers. This paper will discuss one of the key techniques to increase the security for the organizations' data. Multi-Factor Authentication (MFA) is known as a technique that uses two - or more- factors of authentication when accessing the systems/software of the business in order to rise data's protection. However, to design and plan the implementation of such technique, another model is presented and benchmarked with other models mentioned to improve the representation of MFA using Petri Nets.
