  Systems, technologies, protocols, and infrastructures all face
interoperability challenges. It is among the most crucial parameters to give
real-world effectiveness. Organizations that achieve interoperability will be
able to identify, prevent, and provide appropriate protection on an
international scale, which can be relied upon. This paper aims to explain how
future technologies such as 6G mobile communication, Internet of Everything
(IoE), Artificial Intelligence (AI), and Smart Contract embedded WPA3
protocol-based WiFi-8 can work together to prevent known attack vectors and
provide protection against zero-day attacks, thus offering intelligent
solutions for smart cities. The phrase zero-day refers to an attack that occurs
on the day zero of the vulnerability's disclosure to the public or vendor.
Existing systems require an extra layer of security. In the security world,
interoperability enables disparate security solutions and systems to
collaborate seamlessly. AI improves cybersecurity by enabling improved
capabilities for detecting, responding, and preventing zero-day attacks. When
interoperability and Explainable Artificial Intelligence (XAI) are integrated
into cybersecurity, they form a strong protection against zero-day assaults.
Additionally, we evaluate a couple of parameters based on the accuracy and time
required for efficiently analyzing attack patterns and anomalies.
