AIS-189: Automotive Cybersecurity Standard for India

Why AIS-189 Exists

Cars today are not just mechanical systems; they are complex computer networks on wheels.

A modern vehicle may have 100+ ECUs, each connected through CAN, LIN, or Automotive Ethernet, exchanging millions of messages per second.

With connectivity comes exposure — to hackers, spoofing, firmware tampering, and even remote control attacks.

Globally, regulations like UNECE R155 and ISO/SAE 21434 were created to ensure vehicles are designed with cybersecurity in mind.

India followed this global direction through AIS-189 a standard that mandates:

Cybersecurity-by-design in all automotive electronics.

A secure software and hardware development process.

Continuous monitoring and post-production updates.

By 2027, every new vehicle sold in India must comply with AIS-189

This isn’t just a compliance issue
It’s about building trust between drivers, manufacturers, and the digital systems that move us.
