Embedded firewall fends off cyberattacks against car ECUs

Embedded firewall protects automotive systems
To better protect vehicles from cyberattacks commercial Certificate Authority Sectigo,  and a provider of purpose-built and automated PKI management solutions, has released the Sectigo Embedded Firewall for Automotive.

As a part of the company’s IoT Identity Platform, the product was developed specifically for transportation security. To speed adoption–and security–across the automotive supply chain, EDA software vendor Mentor has integrated the Sectigo Embedded Firewall for Automotive with its Autosar platform. 

To protect from cyber-attacks against connected vehicles, automotive manufacturers need an embedded firewall to control traffic into the exposed electronic control units (ECUs) in a vehicle, similar to how a firewall protects home and corporate networks. Embedded firewalls help prevent access from outside cyberattacks on a car’s electronics, while still enabling authenticated access for software upgrades and updates. 

According to the vendor, the Sectigo Embedded Firewall for Automotive is the only security solution that has been embedded within automotive ECUs to provide anomaly detection, stateful packet inspection, rules-based filtering, and threshold-based filtering.

By protecting ECUs such as advanced driver assistance systems (ADAS), steering, braking, etc. from attack, the firewall prevents access from outside cyberattacks on a car’s electronics, while enabling access to upgrades and updates. The firewall:

  • Works with Autosar, Real Time Operating Systems (RTOS) and Linux to configure filtering rules
  • Offers deep packet inspection for industrial protocols, including CAN bus
  • Meets the requirements of automotive systems by enforcing defined security policies, limiting communication with vehicle control systems to a small set of trusted hosts, and blocking attacks from any other source.
