Application of Constraint Satisfaction framework to zero trust security Model

Abstract

The zero-trust era has dawned with the advent of security models which addresses the gap between established security models. As cyber-security risks are advancing with the various natures of attacks, the threat has to be minimized by application of robust security models based on mathematical foundations. This study attempts to rehash few challenges existing in popular trust computing models and tries to bring out the characteristic features of constraint satisfaction framework to deploy zero security models in ubiquitous computing ecosystems. By applying constraint satisfaction in development of trust models, we represent the trust value to be minimum or which tends to zero-in a secure computing environment. We have arrived at a zero-trust model in such a scenario where the proposed framework proves to induce zero trust. We intend to draw light on the inherent challenges in applying the zero trust models which in future will become a pertinent aspect in secure computing establishments. Be it IoT ecosystem or any other smart environment under the spectrum of Industry 4.0, zero trust models will hold the fort of security in years to come.
