What is it about?

Technologies such as artificial intelligence (AI), blockchain, and the Internet of Things (IoT) have converged in driving the next wave of digital revolution. Amalgamating the aforementioned advancements with critical infrastructure (CI) can significantly help society by offering a quality of life and boosting the nation’s economy and productivity. However, the lack of cybersecurity in CI gave rise to advanced threats and vulnerabilities that hindered the aforementioned societal benefits. In this vein, the paper provides an in-depth analysis of cyber threats and risks associated with different critical infrastructures, such as the financial, agriculture, energy, and healthcare sectors. Further, we thoroughly investigate the staggering benefits of AI and, based on it, present an exhaustive solution taxonomy to showcase the competency of AI mechanisms in confronting cyberattacks on CI. The taxonomy specifically addresses issues like data privacy, algorithmic bias, and human-AI collaboration for CI. Further, we proposed an AI-based secure data exchange framework for smart grid CI, where we attempt to secure the sensor’s data (i.e., power consumption, energy readings, and network data) from malicious adversaries. The proposed framework is evaluated using statistical measures, such as accuracy, training time, and receiver operating characteristic (ROC) curve, and anomaly detection. Further, the paper examines the research challenges that still adhere to the critical systems and require stringent AI-based mechanisms to tackle them.

Why is it important?

Critical infrastructures are essential pillars for any nation’s economic growth and development. The advent of IoT has transformed traditional CI into more interconnected and intelligent systems, revolutionizing the way they operate and interact with each other. It allows seamless communication and data exchange between various components of CI, such as power grids, transportation networks, and healthcare systems. However, IoT networks still rely on legacy protocols that jeopardize the operational performance of any CI.

Perspectives

This research paper delved into implementing AI in cyber security for CI. Exploring the transformative potential of AI-based solutions and the challenges faced in safeguarding essential systems through an extensive literature review, historical analysis, and case study. Further, we highlighted the significant impact of AI on detecting, preventing, and mitigating cyber threats.
