Glossary

AI security, clearly defined.

A starting point for understanding the language of AI risk and defense.

A

Adversarial machine learning

Techniques that deliberately influence a machine learning system’s inputs, training data, or behavior.

A

Agent

Software that uses a model to choose steps or tools in pursuit of a task. Its permissions define much of its security exposure.

A

AI guardrail

A control applied around an AI system to constrain inputs, outputs, actions, or access.

D

Data poisoning

Deliberate interference with data used to train, tune, retrieve, or evaluate a model.

M

Model artifact

A packaged model and the files, dependencies, and metadata needed to use it.

P

Prompt injection

Untrusted instructions that attempt to redirect a model or its surrounding application away from its intended task.

R

Red teaming

Authorized testing that challenges a system’s assumptions, controls, and behavior through adversarial scenarios.

R

Runtime security

Controls and monitoring applied while an application or model is operating.

S

Supply chain

The people, packages, models, data sources, and infrastructure on which a system depends.

Put understanding into practice.

Talk through your application, your infrastructure and the questions you want an assessment to answer.
