Driving Security Forward: Why Cybersecurity is Now Mission-Critical in the Automotive Sector

By Nichola Hedges -

As vehicles evolve into rolling data centres, the automotive industry is undergoing a digital transformation unlike anything we’ve seen before. From autonomous driving systems to over-the-air software updates, today’s cars are as much about code as they are about combustion or kilowatts.

But with innovation comes risk—and that’s where cybersecurity project managers play a pivotal role.

The Connected Car: A New Attack Surface

Modern vehicles are equipped with dozens of Electronic Control Units (ECUs), connected via internal networks and increasingly linked to the outside world through cellular, Wi-Fi and Bluetooth. This connectivity enables convenience and performance—but it also opens the door to cyber threats.

A single vulnerability in a vehicle’s software stack can be exploited to:

Remotely control vehicle functions (as demonstrated in high-profile Jeep and Tesla hacks)

Access personal data from infotainment systems

Disrupt fleet operations in logistics and mobility services

Undermine brand trust and trigger costly recalls

Why Cybersecurity Must Be Built In—Not Bolted On

Cybersecurity in automotive can no longer be an afterthought. It must be integrated from the earliest stages of design and development. This means:

Threat modelling during system architecture planning

Secure coding practices across all software layers

Rigorous testing and validation of firmware and OTA updates

Compliance with standards such as ISO/SAE 21434 and UNECE WP.29

Project managers are the linchpins in ensuring these practices are embedded across cross-functional teams—from engineering to compliance to supply chain.

The Lifecycle Challenge: Security Doesn’t End at Launch

Unlike traditional IT systems, vehicles remain in use for 10–15 years. That means cybersecurity must be maintained throughout the vehicle’s lifecycle. This includes:

Monitoring for emerging threats

Patching vulnerabilities remotely

Managing cryptographic keys and certificates

Ensuring secure decommissioning

Project managers must plan for long-term security maintenance, not just product delivery.

Collaboration Is Key

Cybersecurity in automotive is a team sport. It requires collaboration between OEMs, Tier 1 suppliers, software vendors and regulators. Project managers must foster a culture of transparency, shared responsibility and continuous improvement.

The Opportunity Ahead

For cybersecurity professionals, the automotive sector offers a dynamic and high-impact arena. As vehicles become more autonomous, electrified and connected, the demand for skilled cybersecurity leadership will only grow.

If you’re a project manager in this space, your role is not just to deliver secure systems—it’s to help shape the future of mobility.
