Regulated industries cannot treat AI security as an add-on. It must be part of the system architecture from the beginning.
Healthcare, finance, and other regulated teams need controls that are auditable, repeatable, and aligned with policy.
Defense-in-depth baseline
Every regulated AI stack should include:
- data classification and minimization at ingestion
- encryption in transit and at rest
- strict key/secret rotation policies
- PHI/PII detection and redaction before model calls
- immutable audit logging for access and inference events
Secure request lifecycle
Design each request path with explicit checkpoints:
- authentication and role validation
- policy checks on requested action
- retrieval scoped by permissions
- output filtering and compliance checks
- trace logging for auditability
Vendor and model governance
If third-party models are involved, document:
- data retention behavior
- training-data usage policy
- regional hosting and residency guarantees
- incident response and notification obligations
Metrics and readiness
Track both technical and governance health:
- policy violation rate
- time to detect and contain incidents
- audit finding closure time
- percentage of AI flows with full traceability
Security in regulated AI is not a one-time checklist. It is an operating discipline.
