Strengths & Limitations

Strengths

  • +Systematic application of established security frameworks.
  • +Development of a novel defense taxonomy.
  • +Focus on a critical and evolving area of technology.

Limitations

The complexity of real-world cyberattacks can be difficult to fully capture with theoretical models. The effectiveness of the assessment depends on the thoroughness of the threat identification.

Reliability & validity

The reliability of the findings depends on the consistent application of the STRIDE and DREAD models by the researchers. Validity is supported by the systematic evaluation of existing methodologies and the application to a specific system architecture, though generalization to all CCAVs may be limited.

Think critically

To what extent can theoretical threat models like STRIDE and DREAD fully anticipate the dynamic and evolving nature of real-world cyberattacks on complex systems like CCAVs?

Design Principles

"Proactive cybersecurity risk assessment is paramount in the design of complex, interconnected systems."

As vehicles become increasingly connected and autonomous, their reliance on complex hardware-software interactions and cloud infrastructure introduces significant cybersecurity risks. A structured approach to threat analysis and risk assessment is crucial for designers and engineers to proactively identify potential attack vectors and develop robust security measures, ensuring the safety and reliability of these systems.

Paragraph starter

This design project addresses the critical need for robust cybersecurity in connected systems by employing established threat analysis and risk assessment methodologies. Utilizing the STRIDE model, potential threats such as spoofing, tampering, and denial-of-service attacks were systematically identified across the system architecture. Subsequently, the DREAD model was applied to quantify the risk associated with each threat, considering factors like damage, exploitability, and affected users. This structured approach enabled a precise understanding of security requirements and informed the development of targeted mitigation strategies, ensuring a more secure and reliable final product.
