Strategies to secure connected cars
A Practical Infographic for OEMs, Mobility Providers & Tier-1 Suppliers
Connected and software-defined vehicles are rapidly transforming the automotive landscape but they also introduce unprecedented cybersecurity challenges. Today’s vehicles can contain over 150 million lines of code, making them prime targets for sophisticated attacks.
This infographic distills the most pressing threats and provides actionable strategies to protect your vehicles, customers, and brand.
What You’ll Learn
The Evolving Threat Landscape
Real incidents involving connected vehicles—including remote transmission control, key-fob cloning, and sensor manipulation—highlight the urgent need for stronger cybersecurity practices. OEMs face increasing recalls and regulatory pressure as a result.
Attack Surface Categories
- Understand where vehicles are most vulnerable, including:
- Direct Physical Access (e.g., OBD port exploitation)
- Indirect Physical Access via compromised USB devices
- Wireless Threats through Wi-Fi and Bluetooth
- Sensor Spoofing targeting perception systems
Essential Security Layers
- Explore the multilayered approach required to safeguard modern vehicle networks:
- Layer 2 / MACsec for link-level data integrity
- Layer 3 / IPsec for secure IP communication
- Layer 6 / TLS for encrypted network exchanges
- AUTOSAR SecOC for authenticated onboard communication
Firewall Design & Implementation
Learn how rule-based, dynamic, deep-packet, and threshold filtering work together to monitor traffic and stop attacks before they propagate. Review best practices for strategic firewall placement inside vehicle architectures.
