This work presents an advanced security model to prevent vulnerable invasions through highly dense fog networks. Advantages: One of the strengths that fog computing has revealed is how beneficial its native design can be, but on the other hand, one critical aspect to keep in mind is that it brings several fresh security subjects because of its extremely dynamic and decentralized nature. The framework uses anomaly detection and secure communication protocols to identify the potential intrusion into a network. This also includes clustering fog nodes and more frequent network updates to improve security across the whole network. We evaluate our framework by implementing it in simulation experiments. We show that communication among existing trusted peers can be enhanced, whereas non-trusted sources entering the network cannot conduct attacks. Generally, this framework provides an attractive approach to improve fog networks’ security and renders them more attack-resistant.
