A robust firewall security based on software defined networking for mitigating data availability attacks in smart grid AMI network

The global transition from conventional grids to smart grids is advancing rapidly, bringing with it new opportunities as well as challenges. One of the most significant challenges facing the smart grid is safeguarding it against potential cyberattacks. With millions of sensors continuously transmitting and receiving data packets across the network, managing such an extensive system presents a formidable challenge. Cyberattacks can severely compromise the confidentiality, integrity, and availability of the smart grid, undermining its core functions.
The smart grid is comprised of three primary layers, each of which is vulnerable to cyberattacks: customers accessing the network, the communication infrastructure of smart devices and sensors, and the decision-makers responsible for managing the network. In this survey, we examine the various threats and vulnerabilities that can impact the key cybersecurity elements within the smart grid and propose security measures to mitigate these risks across all three levels. Additionally, we recommend techniques to reduce the likelihood of cyberattacks and enhance the resilience of the smart grid at each layer.
