Smart ways to secure your vehicle's data, apps and digital access.

The modern car is no longer just a machine - it's a computer on wheels.

With connected infotainment, mobile apps and even remote start functions, today's vehicles carry just as much data as your smartphone. That convenience comes with a catch: cyber security is now part of car ownership.

Here's how to protect yourself and your car from unwanted digital guests.

Those "update available" alerts aren't just about new features. They often patch critical security flaws discovered by researchers or the manufacturer.

If your vehicle has over-the-air (OTA) updates, let them install promptly. For older models that need dealer servicing, ask specifically whether any software updates are pending when you book in.

The same goes for the apps linked to your vehicle. Whether it's the brand's companion app or a third-party service like a charging-station locator, keep everything current. Out-of-date software is a hacker's easiest entry point.

Many new cars pair to your smartphone for remote lock, start or GPS tracking. If your phone's compromised, so is your car.

Use a strong PIN or biometric lock, enable two-factor authentication on the connected app, and don't share your login casually.

If you sell or trade in your car, perform a full reset of both the car's infotainment system and your app account. You'd be surprised how often old owners still have remote access to their previous vehicles because nobody unlinked them.

It's easy to forget your car broadcasts signals. Public Wi-Fi networks, especially in service stations or parking buildings, can be spoofed. If your infotainment system auto-connects to "free" networks, disable that setting.

Likewise, set Bluetooth to "hidden" or "not discoverable" when not in use. Attackers can use a method called "bluejacking" to try connecting or sending malicious data while your phone or car system is visible.

If you regularly plug in via USB at public chargers or shared EV points, use a data-blocking adapter - it charges your device without exposing data lines.

Cars collect more information than most drivers realise: navigation history, contacts, call logs, even home addresses saved as "favourites." Go through your infotainment settings and clear stored data every so often.

If you're renting or sharing a car, make it a habit to delete paired devices and user profiles when you hand back the keys.

And yes, even dashcams and OBD-II diagnostic devices can be weak spots. Stick to reputable brands with ongoing firmware support, as a cheap gadget with no updates is a bigger risk than it's worth.

That new aftermarket device promising remote stats or better fuel economy? Research it first. Ask whether it encrypts data, who owns the cloud service and how updates are delivered. If answers aren't clear, skip it.

In the same way you wouldn't let an unknown mechanic under the bonnet, don't let an unknown app into your car's brain.

Cybersecurity isn't just for tech buffs anymore. It's basic car care for the connected age.

Staying alert, updating regularly, and managing digital access takes minutes but can save you from a costly, confusing headache later.

Your car keeps an eye on the road. You just need to keep an eye on its network.
