ECU Cyber Security: SELinux & Host Protection – PlaxidityX Ep 3

Cars, Hackers & Cyber Security

As the automotive industry moves toward software-defined vehicles, ensuring the security of ECUs is paramount. ECUs handle critical vehicle functions, and with their increasing connectivity, they are more vulnerable to cyber attacks. SELinux is a trusted solution for managing access control in Linux-based systems, including ECUs, but on its own, it cannot fully meet the stringent requirements of automotive cyber security. To bridge these gaps, many OEMs are turning to Host Intrusion Detection and Prevention Systems (IDPS).

In this episode, we explore how SELinux and Host IDPS work together to secure automotive ECUs. While SELinux provides crucial safeguards by controlling system processes, it lacks the dynamic threat detection capabilities required in today’s automotive landscape. Host IDPS complements SELinux by offering real-time detection, protection against sophisticated cyber threats, and compliance with automotive cyber security regulations, such as ISO 21434 and UNR 155.

We’ll also discuss how this multi-layered approach helps automakers protect vehicles from emerging cyber risks and ensure the safety and integrity of their ECUs. Join us to learn why relying solely on SELinux is not enough and how Host IDPS enhances the overall security of automotive systems.
