TDA4VM ADAS ECU Cybersecurity Requirements

This site is a collection of automotive cybersecurity requirements documents and TARA (Threat Analysis and Risk Assessment) dashboards, organized per ECU. It exists as a learning and interview-preparation resource for grounding automotive cybersecurity concepts in real hardware/firmware facts (TI TISCI mailbox APIs, DMSC, SA2UL, TIFS, eFuse/OTP, etc.) rather than generic textbook descriptions, while following established standards vocabulary (ISO 21434, ISO 14229 UDS, AUTOSAR SecOC).

Requirement ID taxonomy

TARA (Threat Analysis and Risk Assessment - see each ECU’s TARA dashboard) is what supplies the CSG: every Cybersecurity Goal comes from a TARA risk-treatment decision, and each subsequent ID in the chain below is derived from the one before it, in order:

graph LR
    TARA["TARA (Threat Analysis and Risk Assessment)"] --> CSG["CSG (Cybersecurity Goal)"]
    CSG --> FSC["FSC (Functional Security Concept)"]
    FSC --> FSR["FSR (Functional Security Requirements)"]
    FSR --> SYSR["SYSR (System Requirement)"]
    SYSR --> TSC["TSC (Technical Security Concept)"]
    TSC --> TSR["TSR (Technical Security Requirements)"]
    TSR --> HWR["HWR (Hardware Requirement)"]
    TSR --> SWR["SWR (Software Requirement)"]
    HWR --> HSI["HSI (Hardware-Software Interface)"]
    SWR --> HSI

CSG - Cybersecurity Goal (what must be true)
FSC - Functional Security Concept (the overarching strategy for realizing the CSGs)
FSR - Functional Security Requirements (decomposed, testable, still implementation-agnostic)
SYSR - System Requirement (system-level allocation across entities/trust boundaries)
TSC - Technical Security Concept (how, at a functional level)
TSR - Technical Security Requirements (how, at a concrete TI TDA4VM mechanism level)
HWR - Hardware Requirement
SWR - Software Requirement
HSI - Hardware-Software Interface Requirement (register/API/message contract)

Intended use

This is not a product specification for a real vehicle program - it’s a self-contained knowledge base for studying automotive cybersecurity engineering (requirements writing, TARA-based rationale, and TI TDA4VM-specific security mechanisms) in a realistic, traceable format. See the README on GitHub for the full repo/tooling overview.
