If you look at the headlines, the story is about Artificial Intelligence. But if you look at the architecture, the story is about APIs.

The reality of modern tech is simple: You can’t have AI security without API security.

As we move rapidly from simple chatbots to autonomous agents, the way we secure our infrastructure must evolve. That is why we are thrilled to announce the release of the 4th Edition of AI & API Security For Dummies, Salt Security Special Edition.

We have rebuilt this guide to address the seismic shift in the threat landscape. While it still covers the essentials of API discovery and protection, this new edition features a brand-new focus on Chapter 6: Securing the AI-Powered World.

Here is a look at the new concepts we are introducing in this edition and why they matter for your security strategy.

The “Nervous System” of AI

In the new edition, we introduce a core analogy to help visualize the risk: Think of a powerful AI model like a brilliant brain in a jar.

It has incredible capabilities, but it is useless in isolation. It needs a way to see, hear, and act. APIs are the “nervous system” that connects that brain to the real world. Whether you are using a customer service bot or an internal coding assistant, every request is packaged into an API call.

If that nervous system is compromised, the brain, no matter how smart, becomes dangerous.

Securing the “Agentic Action Layer”

The most exciting update to this edition is our deep dive into the Agentic AI Action Layer.

We are moving past the era where a human prompts a bot and gets text back. We are entering a world of Agent-to-Agent (A2A) communication, where multiple specialized AI agents collaborate via APIs to autonomously fulfill complex requests.

Imagine a “Travel Agent AI” talking to a “Flight Agent AI” and a “Hotel Agent AI” to book a trip. These agents use interfaces like Model Context Protocols (MCP) to share context and data.

Securing this web of interactions is critical. As we explain in the book, a vulnerability in just one agent’s API could compromise the entire workflow, allowing attackers to hijack the “action” layer of your enterprise.

New Threats for a New World

With new architecture comes new attack vectors. The 4th Edition details exactly how attackers are exploiting the unique nature of LLMs, including:

• Prompt Injection: How attackers use “social engineering for AIs” to bypass safety guidelines and trick models into revealing sensitive data.
• Model Poisoning: How attackers spam APIs with biased or malicious data to corrupt the model’s learning process.
• Resource Consumption: How a single complex query to a Generative AI model can be used to launch an application-layer Denial of Service (DoS) attack, driving up massive cloud bills.

Mastering API Posture Governance

With great power comes great need for governance. Chapter 3 of the new guide focuses heavily on API Posture Governance, ensuring that your APIs are secure, reliable, and compliant throughout their lifecycle.

This is critical for AI workloads. A simple misconfiguration in an API could accidentally expose massive datasets to an LLM. We discuss how to achieve full visibility into your API landscape, including “Shadow” and “Zombie” APIs, and implement the right controls to stop data exposure before it happens .

The Fundamentals Still Apply

While the AI updates are exciting, this guide remains the definitive resource for foundational API security. We cover:

• The OWASP API Security Top 10: Including deep dives on BOLA (Broken Object Level Authorization).
• API Discovery: How to find and inventory the “Zombie” and “Shadow” APIs lurking in your network.
• Runtime Protection: Why “shifting left” isn’t enough and why you need to stop attacks in real-time.
