Intrusion Detection System Trends: An Overview of Current Advances in IoV & Communication Networks

The proliferation of Internet of Vehicles (IoV) indeed has paved the way for an inter-connected system of transportation, offering unprecedented convenience and efficiency. However, this network is susceptible to various intrusions of malicious means. The volatility of security in IoV arises from the interconnected and dynamic nature of vehicular communication. With the increasing number of connected vehicles and the continuous evolution of communication protocols, the attack surface expands, rendering traditional security measures inadequate. The potential consequences of security breaches in IoV are far-reaching, encompassing safety risks, privacy infringements, and disruptions to critical transportation infrastructure. Threat identification systems emerge as a critical defense mechanism, along with firewalls and other security measures. This paper assesses a comprehensive overview of existing IDS approaches to cater to different kinds of intrusions, implemented in IoV environments or in a different setting. The study provides a comprehensive overview of existing IDS approaches, evaluating their effectiveness in IoV settings as well as in alternative contexts. The discussion encompasses various aspects of intrusion detection within the IoV framework.
