Secure Diagnostics
Authenticated and authorised UDS / OBD diagnostic operations on ECUs.
Secure diagnostics applies authentication (UDS 0x29 or 0x27 security access), authorisation, and audit logging to diagnostic services that can read sensitive data, write calibrations, or unlock ECU functions. Without it, a workshop tool — or a connected attacker — can perform privileged operations on the bus.
