AI Security vs. Security of AI
A practitioner research paper on protecting AI systems, securing AI-enabled enterprises, and using AI for defence

Abstract
"AI security", "security of AI", "secure AI" and "AI for security" are used interchangeably in vendor material, procurement documents and board papers. They describe different problems with different owners, controls and evidence. This paper separates them and gives practitioners a working model for deciding which problem is actually on the table.
The argument has four parts.
- Terminology. Security of AI is the protection of AI systems and their lifecycle. AI for security is the use of AI in defensive work. AI security is the enterprise umbrella that contains both, plus the security consequences of AI-enabled business processes and AI-enabled attackers. (Page 1)
- A two-axis model. Every AI security question can be placed by what is being protected (the object) and what outcome is required (the mission). The same technology, such as a coding agent, generates obligations in several cells at once. (Page 1)
- A design principle. Treat the model as an untrusted component whose output is advisory. Authority to act, access data or spend money must be enforced outside the model by deterministic controls. (Pages 2, 4, 5, 7)
- An operating model. Conventional controls, AI-specific controls and governance controls need to be run as one programme, tied to evidence, and mapped to the standards that auditors and regulators already use. (Pages 8 to 11)
The paper is a synthesis. It does not report new experiments. Where a claim rests on published research or a standards document it is cited; where it is the author's analysis it is labelled as such.
How claims are labelled
| Label | Meaning |
|---|---|
| [Documented] | Stated in a cited paper, standard or regulation |
| [Reported] | Stated in a cited secondary source (vendor, law-firm or community report); verify before relying on it |
| [Analysis] | The author's reasoning or recommendation; not independently evidenced |

Important notice
This is practitioner research, not legal advice, certification guidance or a vendor assessment. Standards and regulations change; confirm the current text and applicability of each instrument before relying on it. AI security is an empirical field, and attack feasibility and mitigation effectiveness change quickly.
