Blockchain Based Network Access Control (NAC) Management Solution and Architecture

There are many advantages of managing services and products in the cyber security sector through a central system, but this can sometimes be a disadvantage. The adequacy of a cyber security product running on a virtual server is limited by the capacity of the virtual server. It is ideal for cyber security products to operate in a distributed structure so that they can work with redundancy and more reliably. One of these products, the network access control management solution, is a product that checks whether the devices are reliable and includes or blocks them in the network. In this study, the model and architecture of a network access control (NAC) management solution has been revealed by choosing blockchain technology because it has a distributed structure, uses cryptography and hash algorithms, and can be processed with smart contracts.
