Transcript — AI Threat Models

Welcome to Lesson 4.1, AI Threat Models.

With the completion of Module Three, we established a strong foundation in AI data governance.

We explored data lifecycle governance, lawful basis, data residency, lineage, provenance, and privacy-preserving AI techniques.

Those governance controls help organizations manage information responsibly throughout the AI lifecycle.

However, effective AI governance requires more than data management.

Organizations must also understand security.

As AI adoption accelerates, attackers are increasingly targeting AI systems.

These attacks often differ from traditional cybersecurity threats.

They may target training data.

Manipulate model behavior.

Exploit inference processes.

Steal models.

Influence outputs.

Or undermine trust in AI-driven decisions.

As a result, organizations need new approaches for identifying and managing AI-specific risks.

This is where threat modeling becomes essential.

Threat modeling helps organizations understand what could go wrong before incidents occur.

It provides a structured method for identifying threats, assessing risks, and prioritizing security controls.

In many ways, threat modeling serves as the foundation of AI security governance.

Before organizations can defend AI systems, they must first understand what they are defending against.

This lesson explores AI threat models, threat actors, attack surfaces, attacker objectives, and the role threat modeling plays in modern AI risk management.

Let’s begin with a simple definition.

Threat modeling is a structured process used to identify potential threats against a system, understand how those threats might occur, evaluate potential impacts, and determine appropriate mitigations.

The objective is not to predict every possible attack.

That would be impossible.

Instead, the objective is to understand likely risks and establish appropriate controls before problems occur.

Threat modeling encourages proactive thinking.

Rather than waiting for incidents, organizations analyze risks during design, development, deployment, and operational activities.

This approach improves resilience and supports more effective security governance.

Traditional threat modeling has existed within cybersecurity for many years.

Organizations routinely evaluate threats against networks, applications, databases, and infrastructure.

However, AI introduces new attack surfaces and new forms of risk.

As a result, traditional approaches often require adaptation.

AI systems possess characteristics that make them different from conventional software.

They learn from data.

They generate predictions.

They evolve over time.

They may incorporate third-party models.

And their behavior may change as operational environments change.

These characteristics create new security considerations that organizations must address.

One of the first steps in threat modeling involves identifying assets.

Assets are anything valuable that requires protection.

In AI environments, assets extend beyond infrastructure.

Training datasets are assets.

Models are assets.

Inference services are assets.

Feature stores are assets.

Model registries are assets.

Governance documentation may even be considered an asset.

Organizations should understand what they are protecting before attempting to identify threats.

Asset identification provides the foundation for effective risk analysis.

Once assets are identified, organizations evaluate attack surfaces.

An attack surface refers to any point where an attacker may interact with, influence, access, or exploit a system.

AI systems often have larger attack surfaces than organizations initially realize.

Training pipelines may be exposed.

Data ingestion processes may be exposed.

Application interfaces may be exposed.

Model endpoints may be exposed.

Third-party integrations may be exposed.

Every connection creates potential risk.

Understanding attack surfaces helps organizations focus security efforts where exposure is greatest.

Now let’s discuss threat actors.

A threat actor is any individual, group, or entity capable of causing harm.

Threat actors may have different motivations and capabilities.

Understanding those motivations helps improve threat assessments.

External attackers represent one category.

These individuals may seek financial gain, intellectual property theft, disruption, competitive advantage, or reputational damage.

Some attackers target AI systems specifically because models represent valuable assets.

Others may seek access to sensitive training data.

Cybercriminal groups increasingly recognize that AI environments can contain valuable information and capabilities.

Insider threats represent another important category.

Insiders may include employees, contractors, vendors, or partners with authorized access.

Because insiders often possess privileged knowledge, they may bypass controls that would stop external attackers.

Insider threats may be intentional or accidental.

A malicious insider may intentionally alter data or expose sensitive information.

An unintentional insider may create risk through mistakes or poor security practices.

Threat modeling should consider both possibilities.

Another category involves third-party risks.

Modern AI systems frequently rely on vendors, cloud providers, APIs, foundation models, datasets, and external services.

Each dependency introduces potential exposure.

If a third-party component is compromised, downstream systems may be affected.

This is why AI security increasingly overlaps with supply chain security.

Organizations must evaluate not only direct threats but also indirect threats originating from dependencies.

Attacker objectives are equally important.

Different attackers pursue different goals.

Some seek to steal data.

Some seek to steal models.

Some seek to manipulate outputs.

Others seek disruption.

Understanding attacker objectives helps organizations prioritize defenses appropriately.

For example, an organization protecting highly valuable proprietary models may prioritize intellectual property protection.

An organization operating safety-critical AI systems may focus heavily on output integrity and reliability.

Threat modeling helps align security priorities with business realities.

One of the unique aspects of AI security is the importance of model integrity.

Traditional cybersecurity often focuses on protecting systems from unauthorized access.

AI security also focuses on protecting model behavior.

An attacker may not need to steal a model to cause harm.

Simply influencing outputs may be sufficient.

If an attacker can manipulate model behavior, trust may be undermined even when infrastructure remains secure.

This expands the scope of security considerations.

Data-related threats also play a major role.

AI systems depend heavily on training and operational data.

If attackers influence that data, model performance may suffer.

If data quality declines, outputs may become unreliable.

If sensitive information is exposed, privacy risks may emerge.

Because data plays such a central role in AI, data-related threats often receive significant attention during threat modeling exercises.

Governance teams should understand that protecting AI systems often means protecting data as much as protecting infrastructure.

Threat scenarios help organizations visualize risks.

A threat scenario describes a plausible sequence of events leading to harm.

For example, a threat scenario might involve an attacker gaining access to a model endpoint and exploiting weaknesses to manipulate outputs.

Another scenario might involve unauthorized modifications to training datasets.

Another might involve compromise of a third-party provider.

Threat scenarios help translate abstract risks into concrete situations.

This improves communication between technical and governance stakeholders.

Threat modeling also supports risk assessment.

Not every threat deserves equal attention.

Organizations should evaluate likelihood and impact.

Some threats may be highly probable but relatively low impact.

Others may be unlikely but catastrophic.

Risk assessments help organizations prioritize resources and determine where security investments should be focused.

This prioritization becomes increasingly important as AI environments grow in complexity.

Governance plays an important role throughout this process.

Threat modeling should not be viewed as a purely technical exercise.

Governance teams contribute valuable perspectives regarding compliance, accountability, business impact, operational risk, and stakeholder expectations.

Security decisions often involve tradeoffs.

Threat modeling helps organizations make those decisions more effectively.

Another important benefit involves communication.

Threat models provide a common language for discussing risk.

Executives, governance teams, security professionals, engineers, and auditors may all use threat models to understand exposure and evaluate controls.

This shared understanding improves decision-making and supports stronger governance outcomes.

Let’s consider a practical example.

Imagine a financial institution deploying an AI-powered fraud detection system.

The organization identifies several critical assets, including training data, operational models, customer information, and inference services.

Threat modeling identifies potential attack surfaces such as APIs, training pipelines, and third-party integrations.

Threat actors include cybercriminal groups, malicious insiders, and compromised vendors.

Risk assessments evaluate potential impacts.

Governance teams review findings and prioritize controls.

As a result, the organization gains a clearer understanding of risks before incidents occur.

This is the value of threat modeling.

It creates visibility before problems emerge.

For certification exams, remember several important concepts.

Threat modeling identifies potential threats before incidents occur.

Assets represent resources requiring protection.

Attack surfaces represent points of exposure.

Threat actors may be external attackers, insiders, vendors, or other entities.

Attacker objectives influence threat prioritization.

AI systems introduce unique attack surfaces related to models, data, and inference processes.

Threat scenarios help visualize risks.

Risk assessments evaluate likelihood and impact.

Governance teams contribute important oversight and accountability perspectives.

Most importantly, threat modeling is proactive rather than reactive.

The objective is to identify risks before they become incidents.

As we conclude this lesson, remember that AI security begins with understanding threats.

Organizations cannot effectively defend systems they do not understand.

Threat modeling provides the visibility necessary to identify risks, prioritize controls, and strengthen resilience throughout the AI lifecycle.

In this lesson, we explored AI threat modeling, assets, attack surfaces, threat actors, attacker objectives, threat scenarios, risk assessment methodologies, and governance considerations supporting AI security.

In the next lesson, we will examine Data Poisoning and Training Data Attacks, focusing on how attackers manipulate datasets to influence model behavior and undermine AI system integrity.
