• Tabletop exercises at least twice yearly to validate incident playbooks.

Secure development and infrastructure

• Adopt secure SDLC with threat modeling, SAST/DAST, SBOMs, and dependency scanning.
• Harden servers and endpoints; enforce least-privilege service accounts and network segmentation.
• Implement backup, restoration testing, and recovery objectives aligned to clinical needs.

Checklist

• MFA and RBAC enforced for all PHI environments.
• TLS 1.3 everywhere; strong cipher suites only.
• Immutable, queryable audit logs retained per policy.
• Patch management meets defined SLAs; critical fixes expedited.

Device Specifications and Standards

Clinical and regulatory alignment

• Demonstrate AASM guidelines compliance for home sleep apnea testing workflows.
• Align with applicable CMS device standards when devices are used for reimbursable services.
• Document validation, accuracy, and reliability for sensors and scoring algorithms.

On-device security

• Secure boot, signed firmware, and encrypted storage for identifiers and results.
• FIPS-validated cryptographic modules when feasible; hardware-backed keys preferred.
• Local PHI minimization with automatic purge after confirmed upload.

Interoperability and data quality

• Support standard coding and exchange formats to integrate with EHR and sleep lab systems.
• Time synchronization and robust error handling to prevent data drift and gaps.
• Telemetry to flag poor signal quality and prompt patient remediation.

Checklist

• Evidence of AASM guidelines compliance and relevant CMS device standards.
• Signed firmware, encrypted storage, and automatic PHI purge validated in QA.

Data Transmission Protocols

Transport and session security

• Mandate TLS 1.3 transport security with HSTS; consider mutual TLS for device-to-cloud links.
• Use SFTP or HTTPS for batch transfers; disable weak ciphers and legacy protocols.

Integrity, authenticity, and confidentiality

• Digitally sign payloads and use message authentication (e.g., HMAC) to detect tampering.
• Apply field-level encryption for especially sensitive identifiers when crossing multiple services.

Data minimization and context

• Transmit only the minimum data needed: patient name, identifiers required by the provider, and apnea score context.
• Redact optional fields by default; avoid embedding PHI in metadata, filenames, or URLs.

Resilience and delivery assurance

• Queue-and-retry with idempotency keys; confirm receipt via signed acknowledgments.
• Monitor latency, error rates, and failed deliveries; alert and auto-remediate.

Checklist

• All channels enforce TLS 1.3; certificates pinned where appropriate.
