Uncover the vulnerable points of your automotive systems

UN R 155 and other international regulations have made a risk-based approach to vehicle architecture development a prerequisite for type approval. In addition, ISO/SAE 21434 sets the framework for the implementation of these guidelines. Threat Analysis and Risk Assessment (TARA) has thus become an indispensable part of automotive system design and development processes.

Threat Analysis & Risk Assessment methodology

ESCRYPT CycurRISK is a TARA software tool that helps you to uncover and evaluate the potential attack surfaces in automotive systems and architectures at an early stage.

ESCRYPT CycurRISK allows you to systematically identify and analyze threats via attack feasibility (based on attack potential) using attack trees. Damage scenarios are used to assess the impact on road users and your business. The tool provides a structured documentation of threat scenarios and risks to a given system. Further, it allows to compare different variants and to share and reuse knowledge from previous analyses through catalogues. Thus, ESCRYPT CycurRISK enables you to prioritize risks and countermeasures and to create a security concept compliant to the requirements of security engineering processes, ISO/SAE 21434 and UN R 155.
