Automated Automotive TARA Threat Analysis Software

why now?

TARA automation for faster regulatory compliance

Automotive regulation and international standards such as UN R155 and ISO/SAE 21434 require threat analysis and risk assessment. This is a manual, time consuming task that requires extensive cyber security knowledge. Unless done efficiently and accurately, it can have a significant impact on the cyber security posture and time-to-market of vehicles or their components.

FAQs

What is the automotive TARA process (Threat Analysis & Risk Assessment)?

TARA is a systematic methodology to identify cybersecurity threats, assess their likelihood/impact, and prioritize mitigation strategies for vehicle systems. It involves asset identification, threat modeling, attack path analysis, and risk scoring, aligned with ISO/SAE 21434 requirements
Is TARA a one-time process?
No. TARA must be repeated whenever:
- New components are added.
- Software is updated.
- New threats are identified (e.g., zero-day vulnerabilities)
Is TARA required by automotive cyber security regulations and industry standards?

Yes. TARA is mandatory under UNECE WP.29 R155 regulation for vehicle type approval. It is also a core requirement of the ISO/SAE 21434 international standard. It ensures compliance with lifecycle cybersecurity risk management obligations
Does TARA apply to automotive components (e.g. ECUs) or to the entire vehicle?

TARA is applied to both vehicle components as well as to vehicles. At the vehicle level TARA assesses system-wide risks (e.g., CAN bus attacks). At the component-level it analyzes specific elements like ECUs, sensors, or communication interfaces
Can you integrate vulnerability management into the TARA

Yes. Vulnerability data (e.g., CVE/NVD feeds) should impact TARA’s feasibility ratings and risk treatment decisions. Automated tools like PX SW Supply Chain Security enable dynamic TARA updates when new vulnerabilities are discovered by integrating into TARA management tools such PX Security AutoDesigner
What are the key benefits of introducing automation into the TARA process?
Some key benefits of introducing automation into the TARA process include:
- Efficiency: Reduces manual effort by 60–80%.
- Time-to-market: reduces delays and accelerates product time to market.
- Consistency: Eliminates human bias in threat scoring.
- Real-time adaptation: Updates risk assessments as threats evolve.
- Audit readiness: Auto-generates ISO 21434-compliant reports.
