ISO SAE 21434: Cybersecurity of Road Vehicles
Automotive cyber attacks are a growing concern for the . Malicious actors can exploit vulnerabilities in vehicles to access their systems, causing chaos, disruption, and safety concerns.
Some of the most common attacks against cars include remote access exploits where bad actors can take control of a 's systems remotely, Wi-Fi hacks that enable bad hackers to gain access to internal networks via the Wi-Fi system, malware, and Bluetooth hacks.
The ISO SAE 21434 provides automakers and other stakeholders in the automotive industry with guidance on how to help protect road vehicles from cyberattacks, including those mentioned above. This post will broadly cover what ISO SAE 21434 is, who it directly affects, and how interested parties can comply.
What is ISO SAE 21434?
