Abstract

The modern vehicles are becoming highly integrative and connected through the use of digital technologies which have transformed the user experience through the infotainment systems. Nonetheless, with this development has come a variety of cybersecurity risks to vehicular networks. The infotainment gateway is one of the most essential points of vulnerability since it is a key node that oversees the flow of data both between the in-vehicle networks and external cloud services through Over-The-Air (OTA) updates. This study examines the architecture, vulnerabilities, and mitigation measures of the lateral attacks in OTA in automotive architecture. It suggests a composite security structure that complements intrusion detection systems (IDS), secure firmware validation schemes, and behavioural checking on the infotainment gateway level to ensure a diminishing of the spread of attacks on both the Controller Area Network (CAN) bus and Ethernet realms. The paper is based on empirical data of actual OTA system, so Indian automotive cybersecurity practises and new regulation framework have been highlighted. Conclusions indicate that the application of a layered defence model under simulated conditions reduces the success of an attempt of lateral intrusion by 82% and therefore the likely success of an attack by a significant margin.
