Architecture-aware automotive TARA for ISO/SAE 21434
Move from vehicle architecture context to a structured TARA — assets, damage scenarios, threat scenarios, attack feasibility, and risk treatment — aligned with ISO/SAE 21434 Clause 15.
WHO THIS PAGE IS FOR
This page is for automotive cybersecurity engineers, TARA leads, and OEM or Tier-1 teams running Threat Analysis and Risk Assessment under ISO/SAE 21434.
THE PROBLEM
TARA is the core risk-assessment method defined in ISO/SAE 21434 Clause 15. It identifies assets, damage scenarios, threat scenarios, attack paths, attack feasibility, and risk-treatment decisions. Done well, it is the spine of the cybersecurity evidence chain. Done in spreadsheets, it is slow, inconsistent, and hard to keep traceable as the architecture changes.
WHERE THE MANUAL WORKFLOW STRUGGLES
Why spreadsheets stop scaling
A manual TARA in spreadsheets typically takes 4–8 weeks per system
Risk ratings drift between engineers and between programmes — there is no shared structure
It does not scale across vehicles with 100+ ECUs
Traceability from asset to threat to control to verification breaks under change
Threat coverage is uneven — engineers reference different sources for different programmes
HOW AGNILE AND KAVACH HELP
An engineering workflow designed to support this
KAVACH ingests vehicle architecture and builds a cybersecurity digital twin — assets, interfaces, data flows, and trust boundaries become the working surface
Architecture-aware threat identification draws on a curated automotive cybersecurity corpus, so coverage is consistent across programmes
Risk scoring is structured per ISO/SAE 21434 Clause 15 — damage scenarios, attack feasibility, risk determination, risk treatment
Engineer-in-the-loop review at every stage; AI-assisted acceleration can be configured or disabled per programme
Agnile engineering services support TARA delivery where the programme needs added capacity
REQUIRED INPUTS
- Vehicle or system architecture description
- ECU, interface, and network list with data flows
- Trust boundaries and external exposure
EXPECTED OUTPUTS
- Structured TARA — assets, damage scenarios, threats, attack paths, attack feasibility, risk determination, risk treatment
- Control mapping aligned with ISO/SAE 21434 Clause 15
- Reviewable work-product evidence
Actual programme outputs depend on scope, architecture, and the engineering review process.
