Automotive Cybersecurity: How to Prevent Vulnerabilities in Software

Security & Compliance
Static Analysis

Automotive cybersecurity is really important. Especially as software in cars is increasingly connected. In this blog, we share how to prevent automotive cybersecurity vulnerabilities.

Why Cybersecurity in Automotive Is Important

Cybersecurity in automotive embedded software is critical. It's the only way to ensure that automotive software is bulletproof and secure. This improves the security of the vehicle. It keeps passengers safe. And it protects manufacturers and developers. It reduces the risk of damage to reputations.

But, how do you ensure automotive cybersecurity?

That's where it gets tricky.

Knowing where to focus your time and energy can be half the challenge. You can trace most security issues back to software vulnerabilities. And these can be easily prevented.

Top 2 Automotive Cybersecurity Vulnerabilities

Here are two key automotive cybersecurityvulnerabilities — and how to prevent them.

Memory Buffer Problems  

Memory buffer problems are the top automotive cybersecurity vulnerability. This means that software can read or write to locations outside of the boundaries of the memory buffer. One example is buffer overflow.

This includes: 

  • Not checking size of input on copy.
  • Bug allowing writing to arbitrary locations.
  • Out-of-bounds read.
  • Pointers outside expected range.
  • Untrusted pointer dereference.
  • Uninitialized pointers.
  • Expired pointer references.
  • Access of memory beyond buffer end.

It's important to keep memory buffer issues from impacting automotive cybersecurity. 

Code Injections

Code injections are another type of automotive cybersecurity vulnerability. They affect interpreted environments. Code injection most often affects infotainment systems and other complicated in-vehicle systems. 

It's important to prevent code injection attacks to ensure automotive cybersecurity.

How to Prevent Automotive Cybersecurity Vulnerabilities

Here's how to prevent automotive cybersecurity vulnerabilities:

  1. Use design review, manual analysis, and automated static analysis. 
  2. Make sure that you’re aware of all your black box components. Keep them up-to-date.  
  3. Don’t assume that everything is within your own system. Pay special attention to items that may be pulling from a website. 

Static code analysis can help.
