A review of security attacks and intrusion detection in the vehicular networks

With the proliferation of Vehicular Ad Hoc Networks (VANETs), ensuring the security and integrity of communication within these networks has become a paramount concern. This paper elaborates on the architecture, characteristics, security services, and various threats in the VANET. Moreover, this paper presents a comprehensive review of Intrusion Detection Systems (IDS) designed for VANETs, aiming to thoroughly understand the challenges, existing solutions, and future directions in this dynamic field. A discussion of the current practices on the evaluation techniques, tools, and datasets is shown. The paper emphasises the need for adaptive and resource-efficient IDS mechanisms, real-world validation, and a deeper exploration of the practical impact of security threats on specific vehicular functionalities. This review serves as a foundation for future research directions to enhance the security of VANETs, contributing to the evolution of intelligent transportation systems.
