Trainers Treasure - All that makes a perfect trainer: ISO/SAE 21434 — CYBERSECURITY FOR ROAD VEHICLES From Connected Vehicles to Cyber-Resilient Mobility

Course Introduction

The automobile has evolved.

What was once primarily a mechanical machine has become a complex, software-driven, connected and increasingly intelligent system. Modern vehicles contain dozens of Electronic Control Units (ECUs), millions of lines of software code, multiple communication networks, sensors, cameras, cloud connections, mobile applications, diagnostic interfaces and over-the-air (OTA) update capabilities.

This transformation has created enormous opportunities—but it has also created a new class of engineering risks.

A vulnerability in a vehicle component may no longer remain confined to that component. A weakness in an ECU, communication interface, diagnostic port, mobile application, cloud service, software library or supplier component can potentially become an entry point into a much larger vehicle ecosystem.

The question is no longer:

"Can we build a vehicle that works?"

The question is:

"Can we build a vehicle that continues to work safely and securely when someone deliberately tries to make it fail?"

That is the thinking behind ISO/SAE 21434 — Road Vehicles — Cybersecurity Engineering.

WHY THIS COURSE MATTERS

Cybersecurity cannot be treated as something that is added at the end of vehicle development.

It must be considered from the moment a system is conceived, through architecture, software and hardware development, testing, production, deployment, operation, maintenance, software updates and eventual decommissioning.

This requires a fundamental change in mindset:

From:

"Find vulnerabilities before launch."

To:

"Engineer cybersecurity into the product and its lifecycle."

ISO/SAE 21434 provides a structured framework for managing cybersecurity risks throughout the lifecycle of automotive electrical and electronic systems.

But understanding the standard is only the beginning.

The real value comes from being able to apply its principles to real vehicles, real components, real projects and real engineering decisions.

THINK LIKE AN ATTACKER.

ENGINEER LIKE A DEFENDER.

During this programme, participants will be challenged to look at an automobile from two different perspectives.

THE ATTACKER ASKS:

Where can I enter?

What can I access?

What vulnerability can I exploit?

What happens if I modify it?

Can I move from one system to another?

Can I remain undetected?

THE ENGINEER ASKS:

What are our critical assets?

What can go wrong?

What is the potential impact?

How do we assess the risk?

What cybersecurity goal do we need?

What security requirement should we define?

How do we implement the control?

How do we verify that it actually works?

FROM COMPONENT TO VEHICLE

Video on Internet Security

A central idea throughout this programme will be:

A component does not exist in isolation.

Consider a simple ECU.

It may communicate with:

Sensors → ECU → CAN/Ethernet → Gateway → Other ECUs → Telematics → Cloud → Mobile Application

Now imagine that one component contains a vulnerability.

The important question is not simply:

"Is this component vulnerable?"

The more important question is:

"What could an attacker do with that vulnerability, and what could ultimately be affected?"

This is where Threat Analysis and Risk Assessment (TARA) becomes critical.

THE PRACTICAL LEARNING MODEL

Participants will use a simple working framework throughout the programme:

COMPONENT

What are we analysing?

↓

ASSET

What needs to be protected?

↓

VULNERABILITY

Where could the weakness exist?

↓

ATTACK PATH

How could an attacker reach it?

↓

THREAT

What could the attacker do?

↓

DAMAGE

What could happen?

↓

RISK

How significant is the risk?

↓

CYBERSECURITY GOAL

What must we protect?

↓

REQUIREMENT

What must the system do?

↓

CONTROL

How will we protect it?

↓

VERIFY

How will we prove that the protection works?

This transforms cybersecurity from an abstract concept into an engineering decision-making process.

THIS IS NOT JUST AN ISO AWARENESS PROGRAMME

Over these two days, participants will not simply listen to presentations.

They will:

Map vehicle attack surfaces
Identify assets
Analyse vulnerabilities
Build threat scenarios
Conduct practical TARA exercises
Use Fishbone and 5-Why analysis
Develop cybersecurity goals
Convert threats into cybersecurity requirements
Identify security controls
Analyse ECU and vehicle interfaces
Examine OTA security
Explore supplier cybersecurity
Examine production and manufacturing risks
Connect cybersecurity with functional safety
Work through incident-response scenarios
Build cybersecurity checklists
Develop practical action plans
Apply the learning to a real component or system from their work environment

THE MINDSET WE WANT TO BUILD

The objective is not to make every participant a cybersecurity specialist.

The objective is to make every participant cybersecurity-aware in the decisions they already make.

An engineer changing software should think:

"What new cybersecurity risk does this change introduce?"

A designer adding an interface should ask:

"What new attack surface have we created?"

A supplier-quality professional should ask:

"What cybersecurity evidence should I expect from this supplier?"

A manufacturing engineer should ask:

"Can this programming or diagnostic station become an entry point?"

A tester should ask:

"Can I demonstrate that the cybersecurity requirement actually works?"

A project manager should ask:

"What cybersecurity risks remain open before release?"

A leader should ask:

"Who owns this risk, and where is the evidence?"

THE 5-STEP COURSE FRAMEWORK

Throughout the programme, we will use:

C — CONNECT

Understand the vehicle, system and attack surface.

A — ASSESS

Identify assets, vulnerabilities and threats.

R — RISK

Conduct TARA and understand potential consequences.

E — ENGINEER

Develop cybersecurity goals, requirements and controls.

S — SUSTAIN

Verify, monitor, respond and continuously improve.

CONNECT → ASSESS → RISK → ENGINEER → SUSTAIN

THE ULTIMATE OBJECTIVE

At the end of these two days, participants should not merely be able to answer:

"What is ISO/SAE 21434?"

They should be able to answer:

"What does ISO/SAE 21434 mean for MY component, MY project, MY process and MY vehicle?"

And more importantly:

"What can I do differently tomorrow?"

Because automotive cybersecurity is not achieved by a document, a certificate or a single security test.

It is achieved when cybersecurity becomes part of everyday engineering, manufacturing, supplier management, testing, decision-making and continuous improvement.

Case Study: Jeep Cherokee Remote Hacking

"When the Infotainment System Became a Path to Vehicle Functions"

Case-study purpose

This case demonstrates one of the most important lessons in automotive cybersecurity:

A component that appears to be an infotainment or connectivity system can become a cybersecurity pathway to safety- and vehicle-critical functions when appropriate security boundaries and controls are absent.

In 2015, security researchers Charlie Miller and Chris Valasek demonstrated remote compromise of a 2014 Jeep Cherokee. Their research showed that a vulnerability in the vehicle's Uconnect connectivity/infotainment system could be used as a pathway into the vehicle's internal networks and ultimately affect certain physical vehicle functions. (WIRED)

The demonstration became one of the landmark events in automotive cybersecurity and contributed to a recall involving approximately 1.4 million affected vehicles equipped with certain Uconnect systems. (NHTSA)

1. CASE BACKGROUND

Vehicle

2014 Jeep Cherokee

Researchers

Charlie Miller and Chris Valasek

Technology involved

Uconnect infotainment/connectivity system

Connectivity

The Uconnect system had cellular connectivity, which created a pathway between the vehicle and external networks.

Internal vehicle network

The vehicle's electronic control systems communicated over internal networks including the CAN bus.

Core security problem

The critical architectural lesson was not simply "the infotainment system had a vulnerability."

The deeper issue was:

A remotely reachable component was connected deeply enough into the vehicle architecture that compromise could be leveraged toward other vehicle systems.

The researchers demonstrated that the compromised head unit could be used to send messages into the vehicle's internal CAN network and affect certain vehicle functions. (WIRED)

2. WHAT HAPPENED?

The research demonstrated a chain broadly equivalent to:

This is the most important diagram for your training session.

Don't focus the participants on the specific exploit.

Focus them on the architectural journey of the attack.

3. THE "HOW CAN THIS HAPPEN?" QUESTION

Put this question on the screen:

"How can an apparently harmless infotainment/connectivity pathway potentially become a pathway toward vehicle functions?"

Give participants 3 minutes individually.

Then ask them to discuss in groups.

Expected thought process:

Stage 1

The attacker is not necessarily starting with the braking or steering system.

They begin with an externally reachable connected component.

↓

Stage 2

That component has a software vulnerability.

↓

Stage 3

The attacker gains control over the compromised component.

↓

Stage 4

The compromised component has communication pathways into the vehicle's internal network.

↓

Stage 5

Insufficient isolation allows messages to reach systems beyond the original infotainment function.

↓

Stage 6

The attack therefore moves from:

Cyber domain → Vehicle network → Physical consequences

That is the core lesson.

4. ATTACK CHAIN — DEFENSIVE VERSION

For your training, represent the incident as:

Stage	What happened conceptually	ISO/SAE 21434 question
1	External connectivity existed	What is the attack surface?
2	Vulnerability existed in connected software	What vulnerabilities must be considered?
3	Attacker reached the connected component	What is the entry point?
4	Component was compromised	What assets were exposed?
5	Compromised component had internal network access	Is the trust boundary appropriate?
6	Internal messages could reach other systems	Is network segmentation sufficient?
7	Vehicle functions were affected	What is the damage scenario?
8	Physical consequences became possible	How should impact be assessed?
9	Manufacturer developed mitigation	What risk treatment is required?
10	Software update/recall followed	How should vulnerabilities be managed throughout the lifecycle?

5. IDENTIFY THE ENTRY POINT

Ask participants:

Where did the attacker enter the vehicle ecosystem?

Expected answer

The attack leveraged the vehicle's externally connected Uconnect system.

The researchers identified a remotely accessible vulnerability associated with the Uconnect system's connectivity. Contemporary technical reporting described the cellular-connected Uconnect system as the remote entry pathway. (IEEE Spectrum)

Training lesson

The entry point was not an obvious mechanical component.

It was:

Connectivity + software + an externally reachable interface

ISO/SAE 21434 connection

Participants should ask:

What external interfaces exist?
Which interfaces are remotely reachable?
Which services are exposed?
What assets can those interfaces eventually reach?
What trust boundaries exist after initial access?

6. IDENTIFY THE VULNERABLE COMPONENT

Component

Uconnect head unit / infotainment system

It was supplied as part of the vehicle's electronic architecture and provided functions including entertainment, navigation/connectivity and related services.

The researchers found a vulnerability in the head-unit environment that enabled them to gain control of the component and then pivot toward the vehicle network. (WIRED)

Important teaching point

Ask:

"Was the infotainment system itself the final target?"

Not necessarily.

It functioned as an initial foothold and pivot point.

This is an excellent way to explain:

Attack Surface ≠ Final Target

7. IDENTIFY THE TRUST BOUNDARY

"What should happen when an infotainment ECU is compromised?"

Ideal answer

The compromise should remain contained.

A compromised infotainment component should not automatically gain the ability to influence safety- or control-critical systems.

8. THE KEY ARCHITECTURAL LESSON

"COMPROMISE ONE ≠ COMPROMISE EVERYTHING"

This leads directly into:

Segmentation
Least privilege
Gateway security
Authentication
Message validation
Network monitoring
Access control
Intrusion detection
Secure architecture
Defence in depth

9. IDENTIFY THE ATTACK PATH

REMOTE ACTOR

↓

EXTERNAL CONNECTIVITY

↓

UCONNECT

↓

COMPROMISED INFOTAINMENT

↓

INTERNAL VEHICLE NETWORK

↓

CONTROL-RELATED ECUs

↓

VEHICLE FUNCTION

"At which point could we have broken the attack chain?"

Potential answers:

Point 1 - External connectivity → Authentication / access control

Point 2 - Infotainment→ Secure software / vulnerability management

Point 3 Infotainment → internal network → Gateway / segmentation

Point 4 Internal network → Message authentication / filtering

Point 5 Critical ECU → Command validation / least privilege

Point 6 Attack detection → IDS / monitoring / incident response

10. POTENTIAL DAMAGE SCENARIOS

The actual 2015 research demonstrated effects on several vehicle functions, including functions involving braking and steering, under the researchers' controlled test conditions. Contemporary reporting also documented manipulation involving throttle, transmission and other vehicle functions.

For training, don't focus on reproducing those actions.

Instead ask participants to identify the damage scenarios.

Damage Scenario A — Loss of vehicle control

Potential compromise of vehicle-control-related functions could create a safety risk.

Damage Scenario B — Loss of availability

A vehicle function may become unavailable or behave unexpectedly.

Damage Scenario C — Incorrect information

Instrument-cluster or vehicle-status information could potentially be manipulated.

Damage Scenario D — Driver distraction

Unexpected changes to infotainment or vehicle functions could distract the driver.

Damage Scenario E — Privacy impact

Connected systems may expose information such as vehicle/location-related data.

Damage Scenario F — Fleet-level impact

A remotely exploitable vulnerability could potentially affect a large population of similarly configured vehicles.

11. TARA EXERCISE (Threat Analysis and Risk Assessment)

Group assignment

Each group gets one asset.

Group 1 - Infotainment system

"You can install only THREE security controls. Where would you place them?"

Each group must justify its choices.

14. RED TEAM / BLUE TEAM EXERCISE

RED TEAM

Their task:

Identify possible pathways by which compromise of a connected component could propagate toward vehicle functions.

They identify:

☐ External interface
☐ Vulnerable component
☐ Trust boundary
☐ Network pathway
☐ Privilege escalation
☐ Target asset
☐ Potential damage

BLUE TEAM

Their task:

Design controls that prevent the propagation.

They identify:

☐ Authentication
☐ Authorization
☐ Network segmentation
☐ Gateway filtering
☐ Secure boot
☐ Message validation
☐ IDS
☐ Logging
☐ Vulnerability management
☐ Incident response

15. THE "WHAT IF?" EXERCISE

Give participants six hypothetical modifications.

Scenario 1

What if the infotainment system had no connection to the vehicle-control network?

Would the attack path change?

Scenario 2

What if the gateway filtered messages between infotainment and critical ECUs?

Would the potential impact change?

Scenario 3

What if every ECU authenticated critical commands?

What changes?

Scenario 4

What if the vulnerability was discovered before SOP?

What lifecycle activities should have detected/addressed it?

Scenario 5

What if the vulnerability was discovered after 500,000 vehicles were sold?

What changes?

Scenario 6

What if the vulnerability exists in a Tier-1 supplier component?

Who needs to be involved?

This last question naturally leads into:

OEM ↔ Tier-1 ↔ Tier-2 ↔ Software Supplier

and supplier cybersecurity management.

16. INCIDENT RESPONSE EXERCISE

Now change the scenario:

Monday 09:00: Security researchers report a vulnerability.

Monday 10:00: Engineering confirms the affected component.

Monday 14:00: 250,000 vehicles may be affected.

Tuesday: A workaround is identified.

Wednesday: A permanent software update is being developed.

Ask:

What do you do?

First 24 hours

☐ Establish incident team
☐ Validate vulnerability
☐ Identify affected products
☐ Assess severity
☐ Identify affected software versions
☐ Contact relevant suppliers
☐ Assess exploitation evidence
☐ Define containment measures
☐ Establish management communication

First 7 days

☐ Root-cause analysis
☐ TARA reassessment
☐ Develop mitigation
☐ Develop patch
☐ Security testing
☐ Regression testing
☐ Deployment planning
☐ Customer/service communication as appropriate

Longer term

☐ Lessons learned
☐ Update TARA
☐ Update cybersecurity requirements
☐ Update architecture
☐ Update supplier controls
☐ Update security testing
☐ Update cybersecurity knowledge base

17. WHAT ACTUALLY HAPPENED AFTER THE RESEARCH?

This is important because the case should not end with "hackers controlled the Jeep."

The industry response is equally valuable.

The researchers had shared aspects of their findings with Chrysler before the public demonstration, allowing the company to prepare a software fix. FCA subsequently implemented network-level measures and issued a safety recall for approximately 1.4 million vehicles with affected Uconnect configurations.

NHTSA's investigation documents that FCA and its network provider blocked the relevant remote access pathway and that further security evaluation and regression testing identified additional vulnerabilities addressed through network or software changes. (NHTSA)

The FCA recall covered specified 2013–2015 vehicles equipped with certain Uconnect 8.4-inch systems, including the 2014–2015 Jeep Cherokee.

18. THE ISO/SAE 21434 CONNECTION

Now ask:

"If ISO/SAE 21434 principles had been applied rigorously throughout the lifecycle, where could this type of risk have been identified or reduced?"

Build the following mapping with participants.

Jeep Case Lesson	ISO/SAE 21434 Activity
External connectivity	Item Definition
Uconnect interface	Attack Surface Analysis
Internal network connectivity	Architecture Analysis
Vulnerability	Cybersecurity Risk Management
Vehicle-control exposure	Damage Scenario
Attack pathway	Threat Scenario / Attack Path
Potential safety/operational consequence	Impact Assessment
Network isolation	Cybersecurity Concept
Security controls	Cybersecurity Requirements
Security testing	Verification/Validation
Vulnerability discovery	Post-development cybersecurity activities
Software update	Cybersecurity maintenance
Recall	Incident/Vulnerability response
Supplier component	Supplier Cybersecurity Management
Lessons learned	Continuous improvement

19. THE BIGGEST LESSON

"The attack did not begin with the brakes."

It began with connectivity.

Then:

CONNECTIVITY

↓

SOFTWARE

↓

VULNERABILITY

↓

COMPROMISED COMPONENT

↓

NETWORK ACCESS

↓

VEHICLE SYSTEM

↓

PHYSICAL CONSEQUENCE

That is the perfect introduction to cyber-physical risk.

20. PARTICIPANT TAKEAWAY CARD

CONNECTED VEHICLE CYBERSECURITY — 10 QUESTIONS

Before approving a connected automotive system, ask:

☐ 1. What are our external interfaces?

☐ 2. What assets are reachable through those interfaces?

☐ 3. What happens if the connected component is compromised?

☐ 4. What trust boundaries exist?

☐ 5. Can compromise propagate to another ECU?

☐ 6. Is the communication path necessary?

☐ 7. Is the communication appropriately authenticated/authorised?

☐ 8. Can abnormal behaviour be detected?

☐ 9. Can the affected software be updated securely?

☐ 10. Can we demonstrate evidence that the controls work?

21. FINAL FACILITATOR QUESTION

"If the infotainment system in our next vehicle programme were completely compromised tomorrow, what could the attacker reach?"

5 minutes.

"What should the attacker NOT be able to reach—and what architectural control guarantees that?"

This takes participants from awareness → TARA → architecture → cybersecurity requirements, which is exactly the behaviour you want from an ISO/SAE 21434 workshop.

Recommended reference material

The original Miller–Valasek research paper, "Remote Exploitation of an Unaltered Passenger Vehicle," is particularly useful for the facilitator because it documents the research methodology and architecture at a technical level. (IOActive)

The 2015 Black Hat presentation provides the researchers' own technical presentation of the research and its limitations. (infocondb.org)

For a later reflection, Miller and Valasek's 2025 USENIX retrospective, "Ten Years After the Jeep Hack," is useful for discussing what the automotive cybersecurity ecosystem learned during the decade following the demonstration. (USENIX)

Facilitator safety note: For an OEM classroom, use the case to analyse assets, attack surfaces, trust boundaries, TARA, controls and lifecycle response. Do not reproduce the exploit, scan live vehicles, inject CAN messages into production systems, or attempt remote access to vehicles.

MODULE 2

ISO/SAE 21434 — Understanding the Framework

Duration

45 minutes

Introduce:

Four lifecycle perspectives

1. Concept

4. Operations / Maintenance / Decommissioning

ISO describes the standard as covering the cybersecurity lifecycle of vehicle E/E systems and their components/interfaces.

ACTIVITY 2

"Where Does Cybersecurity Begin?"

Give teams 10 cards:

Vehicle concept
Supplier selection
ECU design
Software development
Testing
Production
Vehicle delivery
OTA update

MODULE 3

AUTOMOTIVE ATTACK SURFACE MAPPING

Duration

60 minutes

Attack surfaces

In automotive cybersecurity, a vehicle is no longer an isolated mechanical system—it is a connected ecosystem of in-vehicle networks, external interfaces, software, mobile applications, cloud services, manufacturing systems, and service tools. Each connection creates an attack surface that must be identified, assessed, protected, and monitored throughout the vehicle lifecycle under ISO/SAE 21434. The table below gives a quick practical understanding of each interface with an automotive example.

Interface / System	Short Introduction	Automotive Example	Cybersecurity Concern
CAN	Controller Area Network used for communication between ECUs.	Engine ECU ↔ Transmission ECU ↔ ABS ECU	Unauthorized messages, spoofing, lack of authentication
CAN-FD	Enhanced CAN supporting larger data payloads and higher data rates.	ADAS, powertrain and body-control communication	Message injection, compromised ECU communication
Ethernet	High-speed networking used for modern vehicle systems and diagnostics.	ADAS cameras, infotainment, gateway, zonal controllers	Network intrusion, unauthorized access, malware
OBD	On-Board Diagnostics interface used to access vehicle diagnostic information.	Technician connects a diagnostic scanner during service	Unauthorized diagnostic access, ECU manipulation
USB	Physical interface for data transfer, media and software updates.	USB drive used to update infotainment software	Malicious files, infected USB devices, unauthorized updates
Bluetooth	Short-range wireless communication between vehicle and devices.	Driver connects smartphone to infotainment	Unauthorized pairing, device compromise, data leakage
Wi-Fi	Wireless network connectivity for vehicle occupants and vehicle systems.	In-car Wi-Fi hotspot or wireless software update	Rogue access, credential theft, network intrusion
Cellular	Mobile-network connectivity enabling remote vehicle services.	Connected vehicle communicates with OEM cloud through 4G/5G	Remote attack, unauthorized commands, service disruption
GNSS	Satellite-based positioning system used for navigation and location services.	GPS/GNSS provides vehicle location to navigation system	Spoofing, jamming, manipulated location data
Keyless Systems	Electronic systems that authenticate a key/fob without conventional mechanical keys.	Passive keyless entry and push-button start	Relay attacks, unauthorized vehicle access
Mobile Apps	Smartphone applications that allow owners to interact with vehicles remotely.	Lock/unlock vehicle or check vehicle status through an app	Account takeover, API abuse, unauthorized commands
Cloud	Backend infrastructure supporting connected-vehicle services and data.	OEM cloud receives vehicle telemetry and sends authorised services	API attacks, data breaches, account compromise
OTA	Over-the-Air technology for remotely delivering software/firmware updates.	OEM remotely updates infotainment or ECU software	Malicious update, compromised update server, rollback attacks
Charging Infrastructure	EV charging ecosystem connecting vehicle, charger and backend systems.	EV communicates with an AC/DC charger and charging network	Authentication attacks, charging manipulation, data exposure
Diagnostic Tools	Software/hardware used by technicians to diagnose and configure vehicles.	Workshop technician uses OEM diagnostic equipment	Unauthorized ECU access, credential misuse
Supplier Software	Software, firmware or libraries supplied by Tier-1/Tier-2 vendors.	Supplier provides ECU firmware to an OEM	Vulnerabilities, insecure components, supply-chain compromise
Manufacturing Equipment	Production machines and systems that interact with vehicle ECUs/software.	ECU programming station flashes firmware during assembly	Unauthorized firmware, compromised programming station
Service Tools	Tools used during maintenance, repair, calibration and configuration.	ADAS calibration or ECU configuration tool	Privilege misuse, unauthorized configuration, infected tools

A simple way to remember the attack surface

Vehicle Cybersecurity = Inside the Vehicle + Outside the Vehicle + Vehicle Lifecycle

Area	Examples
Inside Vehicle	CAN, CAN-FD, Ethernet, ECUs, OBD
Wireless / External	Bluetooth, Wi-Fi, Cellular, GNSS, Keyless
Digital Ecosystem	Mobile Apps, Cloud, OTA
EV Ecosystem	Charging Infrastructure
Service Lifecycle	Diagnostic Tools, Service Tools
Supply Chain	Supplier Software
Manufacturing	Manufacturing Equipment

Training takeaway:

“Every interface is a potential entry point; every connection needs a reason, a boundary, a control and evidence that the control works.”

This is an excellent starting point for an ISO/SAE 21434 Attack Surface Identification activity: give each participant/team one interface and ask them to identify Entry Point → Asset → Threat → Attack Path → Damage Scenario → Cybersecurity Control.

ACTIVITY 3

ACTIVITY 7

DESIGN A SECURE VEHICLE

Components

Here is a simple, training-friendly version you can use directly in your ISO/SAE 21434 automotive cybersecurity module:

Component / System	Short Definition	Automotive Example	Cybersecurity Relevance
TCU	Telematics Control Unit – connects the vehicle to external networks such as cellular and cloud services.	Sends vehicle location and diagnostic data to the OEM cloud through 4G/5G.	Remote access, authentication, data protection, cellular attack surface
Gateway	A network controller that manages and filters communication between different vehicle networks.	Allows selected messages to pass between CAN and Ethernet networks.	Critical security boundary; message filtering, segmentation and access control
ADAS ECU	Electronic Control Unit responsible for Advanced Driver Assistance System functions.	Processes radar/camera inputs for Adaptive Cruise Control or Lane Keeping Assist.	Sensor spoofing, malicious inputs, unauthorized commands, data integrity
Infotainment	Vehicle system providing entertainment, navigation, connectivity and driver/passenger information.	Touchscreen system providing navigation, music, Bluetooth and smartphone integration.	Large attack surface through USB, Bluetooth, Wi-Fi and cellular connectivity
Powertrain ECU	ECU that controls or manages vehicle propulsion-related functions.	Engine ECU controls fuel injection, ignition and engine operation.	Unauthorized commands could affect vehicle performance or availability
BMS	Battery Management System – monitors and controls an EV's battery system.	Monitors battery voltage, temperature, State of Charge (SoC) and charging conditions.	Manipulated battery data, unauthorized commands, charging and safety impacts
Cloud	Remote computing infrastructure that stores, processes and exchanges vehicle-related data and services.	OEM cloud receives vehicle telemetry and supports connected-car services.	API security, authentication, data protection and unauthorized remote access
Mobile App	Smartphone application that allows users to access vehicle-related services remotely.	Owner checks battery status or locks/unlocks the vehicle using a smartphone.	Account takeover, insecure APIs, unauthorized vehicle commands and privacy risks

Mobile App → Cloud → Cellular → TCU → Gateway → Vehicle ECUs

For example:

“A simple mobile-app command such as ‘check vehicle status’ may travel through several connected components before reaching the vehicle. Each connection and trust boundary must therefore be considered during cybersecurity analysis.”

Key training question:
If the infotainment system or TCU is compromised, what should the attacker not be able to reach—and which gateway/security control prevents that?

Teams design:

A cybersecurity architecture that limits the attacker's movement.

RED TEAM vs BLUE TEAM

Red Team

Identifies:

Attack paths
Weak trust boundaries
Single points of failure
Excessive privileges
Unprotected interfaces

Blue Team

Designs:

Segmentation
Authentication
Monitoring
Access controls
Detection
Recovery

This can be performed entirely on a paper/simulation architecture, avoiding live vehicle exploitation.

MODULE 10

SECURE DEVELOPMENT, VERIFICATION & VALIDATION

Key concepts

Here is a short, training-friendly table for these automotive cybersecurity verification and testing techniques:

Technique	Short Definition	Automotive Example	Main Purpose
Secure Coding	Developing software using practices that prevent common security weaknesses.	ECU software validates inputs before processing CAN/Ethernet data.	Prevent vulnerabilities at the source
Static Analysis	Examining source code or binaries without executing the software.	Tool detects buffer overflow or insecure function usage in ECU code.	Find coding weaknesses early
Dynamic Analysis	Testing software while it is running to identify abnormal or vulnerable behaviour.	Monitor an infotainment application while feeding different inputs.	Detect runtime security problems
Code Review	Human examination of code to identify security, quality and design issues.	Cybersecurity engineer reviews authentication and access-control code in a TCU.	Identify issues automated tools may miss
Vulnerability Scanning	Automatically checking systems, software or components for known vulnerabilities.	Scan an automotive Ethernet system for known vulnerable services or libraries.	Identify known weaknesses
Penetration Testing	Controlled security testing that attempts to exploit identified weaknesses within an authorized test environment.	Security testers assess whether an infotainment interface can be abused to cross a network boundary.	Validate real-world security resilience
Fuzz Testing	Sending large amounts of unexpected, malformed or randomised inputs to discover failures.	Send malformed diagnostic or network messages to an ECU in a test bench.	Find crashes, unexpected behaviour and input-handling weaknesses
Interface Testing	Testing communication interfaces to ensure only expected and authorized interactions occur.	Verify that a diagnostic interface cannot access functions outside its permitted scope.	Validate interface security and boundaries
Security Requirements Verification	Checking that implemented software/system controls satisfy defined cybersecurity requirements.	Requirement: “Only authenticated users can initiate a software update.” Test whether the control works as specified.	Demonstrate requirements are actually implemented
Regression Testing	Re-testing previously verified functionality after changes to ensure security controls have not been broken.	After an ECU firmware update, repeat authentication, access-control and communication-security tests.	Prevent previously fixed vulnerabilities from returning

Easy way to remember the sequence

Prevent → Inspect → Review → Scan → Attack → Stress → Verify → Re-test

Secure Coding → Prevent
Static Analysis → Inspect code
Code Review → Human review
Vulnerability Scanning → Find known weaknesses
Penetration Testing → Controlled attack simulation
Fuzz Testing → Stress with unexpected inputs
Interface Testing → Test boundaries
Security Requirements Verification → Confirm requirements
Regression Testing → Make sure fixes stay fixed

Training takeaway:

“Finding a vulnerability is not the finish line—verification must demonstrate that the risk has been addressed and remains addressed after every change.”

PRODUCTION & OPERATIONS

Manufacturing Attack Surfaces in Automotive Cybersecurity

Automotive cybersecurity does not stop at the vehicle. Manufacturing and production environments can become attack paths into vehicle software, ECUs, production systems, and intellectual property. A compromised programming station, engineering laptop, supplier connection, or calibration system could potentially introduce malicious or unauthorized changes during vehicle production. Therefore, manufacturing cybersecurity should be considered as part of the vehicle's broader cybersecurity lifecycle.

Manufacturing Attack Surface	Short Definition	Automotive Example	Key Cybersecurity Concern
Programming Stations	Systems used to load software or configuration into vehicle ECUs during production.	Station programs firmware into an engine or body-control ECU.	Unauthorized or malicious firmware
ECU Flashing	Process of installing or updating ECU firmware/software.	Production line flashes approved software into 500 ECUs.	Wrong, outdated or tampered software
Diagnostic Tools	Tools used to diagnose, configure or communicate with vehicle systems.	Technician uses an OEM diagnostic device to configure an ECU.	Unauthorized commands or access
Production Networks	Networks connecting manufacturing machines, computers, PLCs and production systems.	Factory Ethernet connects assembly-line controllers and servers.	Lateral movement and production disruption
Engineering Laptops	Computers used by engineers for development, testing, configuration and troubleshooting.	Engineer connects a laptop to an ECU test environment.	Malware, credentials and sensitive data exposure
USB Devices	Removable storage used to transfer software, configuration files or data.	USB drive transfers ECU calibration data to a production station.	Malware or unauthorized files
Supplier Connections	Digital connections between OEM facilities and suppliers.	Tier-1 supplier remotely provides software or production support.	Supply-chain compromise and unauthorized access
MES	Manufacturing Execution System that monitors and manages production activities.	MES tracks vehicle build status and ECU programming results.	Unauthorized access, data manipulation or production disruption
Manufacturing Servers	Servers supporting production applications, software repositories and manufacturing data.	Server stores approved ECU firmware packages.	Firmware tampering, ransomware, data theft
Test Equipment	Equipment used to test vehicle components and systems during manufacturing.	End-of-line tester verifies ECU communication and functionality.	Unauthorized test commands or compromised equipment
Calibration Systems	Systems used to configure and calibrate vehicle components or ECUs.	ADAS calibration equipment configures camera/radar parameters.	Incorrect or unauthorized calibration

Simple Attack Path

A useful training scenario is:

Supplier Software → Manufacturing Server → Programming Station → ECU Flashing → Vehicle

Ask participants:

“If an attacker compromises the manufacturing environment, what could potentially reach the vehicle—and where should we place controls to stop the attack?”

Manufacturing Cybersecurity Control Points

Stage	Example Control
Software received	Supplier verification + digital signatures
Software stored	Access control + integrity protection
Software transferred	Secure communication + authentication
ECU flashing	Authorised programming + firmware validation
Production network	Network segmentation
USB usage	Controlled/approved removable media
Engineering laptops	Endpoint protection + least privilege
Supplier access	MFA + restricted access + monitoring
Calibration	Authorised configurations + change control
Final vehicle	Software integrity verification + production cybersecurity records

Key message for ISO/SAE 21434 training:

“The vehicle can inherit cybersecurity risk from the factory. Secure the software before it becomes part of the vehicle.”

2. Bollywood / Indian Cinema

1. A Wednesday!

Connection

Cyber/terrorism/security mindset and threat response.

Activity

Show a short relevant scene and ask:

"If the threat were digital instead of physical, what would our incident-response process look like?"

2. Special 26

Connection

Social engineering, deception and human vulnerability.

Training topic

"The weakest link may not always be the technology."

Use it when introducing:

Social engineering
Insider threats
Authentication
Human factors

3. Mard Ko Dard Nahi Hota

Not directly a cybersecurity movie, but selected scenes can be used for a different discussion:

"What happens when a system behaves outside the assumptions made by its designer?"

Useful as a bridge into assumptions, unintended behaviour and risk analysis.

4. Irumbu Thirai

⭐ Strongest Indian cybersecurity choice

This is particularly suitable for your training.

The film directly deals with data theft, hacking and digital crime; contemporary coverage described it as bringing data-theft issues into mainstream Tamil cinema. (India Today)

Recommended Cinema Exercise

Don't simply play movie clips.

Use the:

"HOLLYWOOD vs ISO/SAE 21434" GAME

Show a 2–3 minute scene.

Then give teams this worksheet:

Movie Event	ISO/SAE 21434 Question
System is accessed	What is the attack surface?
Attacker gains access	What asset is compromised?
System behaviour changes	What is the damage scenario?
Attack propagates	What is the attack path?
Vehicle/system affected	What is the impact?
Defence activated	What cybersecurity control is required?
Recovery	How do we restore trust?

This converts entertainment into a TARA exercise.

60-Day Implementation Roadmap

7. The "2026 India Automotive Cybersecurity" Case Study

I strongly recommend making this the final capstone case rather than using only foreign examples.

Scenario

Your OEM has 500,000 connected vehicles on the road.

A vulnerability is discovered involving a connected EV subsystem.

The issue potentially involves:

Mobile App → Bluetooth → BMS → TCU → Cloud → OTA

Participants must answer:

STEP 1 — IDENTIFY

What assets are involved?

STEP 2 — MAP

What is the attack surface?

STEP 3 — TARA

What are the damage and threat scenarios?

STEP 4 — PRIORITISE

Which risks require immediate treatment?

STEP 5 — PROTECT

What cybersecurity controls are required?

STEP 6 — VERIFY

How will we test them?

STEP 7 — RESPOND

What happens if exploitation is confirmed?

STEP 8 — RECOVER

How do we restore the affected vehicles?

STEP 9 — LEARN

What must change in the next vehicle programme?

This scenario is particularly timely because India's 2026 automotive cybersecurity developments are explicitly focusing attention on connected vehicles, EV software, authentication, OTA security and lifecycle cybersecurity. (Business Standard)
