Challenges

Predicting Client Cybersecurity Integration Needs

Developing a platform product without a known target context required advanced knowledge and experience regarding potential clients' preferences for implementing security controls. This was crucial to ensure maximum compatibility and readiness of the security concept in relation to the security designs of potential clients. Effective allocation of responsibilities for security design interfaces and functions was key to success.

Solution Implemented

DIA-Augmented Security Concept

DIA-Augmented Security Concept

Our solution involved creating a security concept where all identified security risks are addressed through three control categories: organization-owned controls, client-configurable security controls, and client-defined security controls. Each control category comes with a set of documented design responsibilities assigned either to the organization or to the client.

For shared and client-controlled controls, an interface specification was provided to assist clients in evaluating the compatibility of the platform product solution with their systems.

Concept design & idea management

  • Review and additional best practices implementation of an existing TARA and cybersecurity concept
  • Creation and execution of a comprehensive method for documenting cybersecurity controls effect on product life cycle phases other than normal operation, particularly effect on operational environment
  • Specification of cybersecurity requirements derived from security concept

Implementation & Development

  • Creation of a dedicated security architecture
  • Modelling of security functions allocation to product elements
  • Modelling of interfaces between product and potential client controlled parts of overall vehicle security solution
