10 Enterprise AI Security Architecture

You now understand the major building blocks of AI Security.

You have learned about:

AI and Machine Learning systems
Generative AI and Large Language Models
Enterprise AI architecture
AI attack surfaces
The AI threat landscape
OWASP GenAI risks
MITRE ATLAS
AI security roles and responsibilities

The final step in Module 01 — AI Security Foundations is to bring these concepts together and answer a practical enterprise question:

How should we design an AI system securely from the beginning?

This is the purpose of Enterprise AI Security Architecture.

An AI Security Engineer must be able to look beyond individual controls and understand how:

Identity
Applications
Models
Data
RAG
AI agents
Cloud infrastructure
APIs
Networks
Secrets
Logging
Governance

fit together as one secure system.

The objective is not simply to add security products.

The objective is to build an architecture where security is enforced throughout the AI lifecycle.

What Is Enterprise AI Security Architecture?

Enterprise AI Security Architecture is the structured design of security controls, trust boundaries, identities, data flows and operational protections around AI-enabled systems.

It answers questions such as:

Who can access the AI?
        ↓
What can they access?
        ↓
What data can the AI use?
        ↓
Which systems can it communicate with?
        ↓
What actions can it perform?
        ↓
How are models protected?
        ↓
How is misuse detected?
        ↓
How do we respond?
