Definition
Inference attacks — submitting carefully crafted input and analysing the output to reveal membership, attributes or features of individuals in the training datasets — increase in severity given larger attack surfaces and natural-language interfaces.

Controls & guardrails that address this
9Grouped by control function, with the AI lifecycle stage(s) to apply each and the other risks it addresses. Filter by control category below.
Design query rate limiting and RBAC for the model inference API at design stage to limit attack surface.
Implement query pattern detection to identify systematic inference attack behaviour (high-volume queries, membership probing).
Train PII-bearing models with DP-SGD under a documented epsilon/delta budget. Approve the budget against the enterprise epsilon-ceiling policy before training.

'Deep Learning with Differential Privacy' (DP-SGD); MITRE ATLAS AML.M0007 (Sanitize Training Data)Strip raw logits, quantise confidence scores and block training-record echoes at the inference gateway. Keep the output-filter policy under change control.

Conduct periodic inference attack vulnerability assessments as new attack methods emerge. Monitor query pattern anomalies.
Attack each candidate model with membership-, attribute-, and inversion-inference harnesses before promotion. Block release when attack advantage exceeds the agreed ceiling.

'Membership Inference Attacks From First Principles' (LiRA); NIST AI RMF MEASURE 2.7Configure per-principal budgets and probing-detection rules on the gateway before exposure. Verify enforcement with synthetic attack traffic.

Define the minimum response surface and test it with membership/attribute-inference probes pre-release. Block promotion if any probe recovers raw confidence signals.

MemGuard (output perturbation defence); OWASP Top 10 for LLM Apps LLM02:2025 Sensitive Information DisclosureMeter inference traffic per principal and flag probing signatures with behavioural analytics. Throttle, step-up, or suspend flagged sessions.
