Cybersecurity Engineering

ISO/SAE 21434 and UN R155-aligned engineering support using ALM tools such as KDP Library for TARA analysis, security requirements, ECU protection, weakness testing, and evidence management.

How tool adoption supports automotive cybersecurity

Automotive cybersecurity has to reach ECU design, communication matrices, diagnostics, software update, and key management. KopherBit uses KDP Library to manage specifications, TARA templates, requirements, test evidence, and cybersecurity knowledge assets, helping connect TARA analysis, cybersecurity goals, design, validation, and vulnerability closure into ALM-backed engineering workflows.

Engineering Focus

TARA Analysis and Requirements

Set up traceability for assets, damage scenarios, threat scenarios, attack paths, risk ratings, and cybersecurity requirements.

ECU Security Implementation

Define Secure Boot, Secure Flash, SecOC, diagnostic authorization, key management, and software update protection.

KDP Library and Weakness Evidence

Adopt fuzzing, static analysis, penetration testing, and issue tracking, then consolidate results, vulnerability closure, and cybersecurity evidence in KDP Library or existing ALM tools.

Engineering Scope

01

TARA Data Model and Templates

Build fields and templates for items, assets, damage scenarios, threat scenarios, attack paths, attack feasibility, and risk ratings.

02

Security Requirements and ECU Design

Turn cybersecurity goals, CSC / TSC, diagnostic permissions, communication protection, key management, and update protection into engineering requirements.

03

Security Validation Tooling

Support fuzzing, static analysis, weakness scanning, penetration testing, diagnostic security tests, and result consolidation.

04

KDP Library and Evidence Tracking

Organize requirements, design, tests, vulnerability closure, and software update records in KDP Library or existing ALM tools as traceable evidence for product review and UN R155 preparation.

Start cybersecurity tool adoption

We help review ECU architecture, communication and diagnostic interfaces, update mechanisms, KDP Library / ALM toolchains, TARA needs, and validation gaps, then turn them into an executable engineering rollout plan.
