Addressing Cybersecurity Challenges in 5G-enabled IoT and Critical Infrastructures: A Comprehensive Overview

Significant advancements in communication and processing technology over the past two decades have led to the emergence of new intelligent objects known as the "Internet of Things" (IoT). These "things" range from wearable technology, such as smartwatches, to infrastructures for transportation, energy, information, health care, and financial services. They are linked through an Internet-connected control system in order to provide services. The majority of modern industrial critical infrastructures (CIs) rely on Supervisory Regulate and Data Acquisition (SCADA) systems to observe, monitor and control the whole business cycle of operations and data. This article aims to overview and study ICT security in the 5G environment, with many outlines connecting security issues and critical infrastructure. Starting with Protecting 5G infrastructure from cyber risks, to SCADA-based IoT critical infrastructure, third the Security and Privacy Issues of Fog Computing Supported Internet of Things, an intrusion detection system (IDS), Best practices to avoid cyber threats, security recruitment, 5G network vulnerabilities. Finally, concluding remarks and future work are discussed.
