Explainability

The degree to which the reasoning behind a model's output can be understood by humans, ranging from inherently interpretable models to post-hoc techniques that approximate feature contributions.

The deliberate placement of human review, approval, or intervention points in an AI workflow so that consequential decisions are not left solely to automated systems.

Human in the loop

A control pattern in which a person reviews and can approve, modify, or reject an AI recommendation before the action is executed, preserving accountability for high-impact decisions.

Related: Human oversight, Automation bias
Automation bias

The human tendency to over-trust automated output and accept it with less scrutiny than an equivalent human judgment, which can undermine the effectiveness of oversight controls.

Adversarial example

An input deliberately perturbed in ways imperceptible to humans so that a model misclassifies it or produces an attacker-chosen output, exploiting the model's learned decision boundaries.

Related: Evasion attack, Adversarial robustness
Evasion attack

An attack performed at inference time in which crafted inputs are submitted to a deployed model to bypass detection or cause a wrong result, without altering the model itself.

Related: Adversarial example, Model poisoning
Model poisoning

Tampering with training data or the training process so that a model learns malicious behavior or hidden triggers, degrading its integrity before or during deployment.

Related: Backdoor trigger, Data provenance
Backdoor trigger

A hidden pattern embedded during training that causes a model to produce attacker-desired output whenever the pattern appears in input, while behaving normally otherwise.

Related: Model poisoning, Supply chain risk
Prompt injection

An attack in which crafted text in user input or retrieved content causes a language model to ignore its instructions and follow the attacker's, potentially triggering unintended tool actions.

Related: Indirect prompt injection, Jailbreak
Indirect prompt injection

A prompt injection delivered through content the model ingests, such as a web page, document, or email, rather than through the user's direct input, making it hard to spot.

Related: Prompt injection, Data exfiltration
Jailbreak

A technique that circumvents a model's safety alignment or content restrictions, often through role-play or reframing, to elicit outputs the provider intended to refuse.

Related: Prompt injection, Guardrail
Model extraction

An attack that queries a deployed model systematically to reconstruct an approximation of its behavior or parameters, enabling theft of intellectual property or cheaper follow-on attacks.

Related: Membership inference, API rate limiting
Membership inference

A privacy attack that determines whether a specific record was part of a model's training data by exploiting differences in how the model responds to seen versus unseen examples.

Related: Model extraction, Differential privacy
Data exfiltration

Unauthorized transfer of sensitive data out of an environment, which in AI contexts can occur through model outputs, tool calls, or plugins manipulated by injected instructions.

Related: Indirect prompt injection, Shadow AI
Supply chain risk

Exposure created by dependencies on third-party models, datasets, libraries, and services whose provenance, integrity, or security practices are outside the organization's direct control.

Related: Backdoor trigger, Model signing
AI red teaming

Structured adversarial testing in which a team deliberately attacks a model or AI system to find safety, security, and misuse weaknesses before adversaries do.

Related: Adversarial example, Guardrail
Adversarial robustness

The ability of a model to maintain correct and safe behavior when subjected to crafted inputs, distribution shift, or other adversarial conditions, often improved through adversarial training.

Related: Adversarial example, Guardrail
Guardrail

A runtime control that constrains model input or output, such as content filters, topic restrictions, or schema validation, to prevent harmful, off-policy, or malformed responses.

Related: Jailbreak, AI red teaming
Differential privacy

A technique that adds calibrated noise to data or query results so that outputs reveal little about any single individual, limiting the success of privacy attacks on models.

Related: Membership inference, Data minimization
Data minimization

The practice of collecting and retaining only the data actually needed for a defined purpose, reducing exposure and regulatory burden when training or operating AI systems.

Related: Differential privacy, Data provenance

The documented origin and history of a dataset, including who collected it, how it was transformed, and what rights apply, used to verify trustworthiness and licensing.
