Boundaries are
part of the design.

Secure architecture

Define trust boundaries between interfaces, services and storage. Separate product data and avoid assuming that an internal component is automatically trusted.

Authentication & authorization

Identify the user or service, then evaluate what it is allowed to do. Use least privilege and scope permissions to the task.

• Role-aware access
• Scoped service permissions
• Separation of patient and staff views

Encryption & secure storage

Protect information in transit and at rest using appropriate, maintained mechanisms. Key management and recovery need as much attention as encryption itself. No certification or universal control coverage is claimed here.

Data isolation & minimization

Collect information required for the workflow, keep unrelated contexts separate and limit retention. Use local processing where it provides a meaningful privacy benefit.

Infrastructure security

Maintain dependencies, restrict operational access and establish deployment and recovery procedures. Reliability and security must be tested in the environment actually used.

Logging & monitoring

Record operational events that support investigation while avoiding credentials, clinical content and unnecessary personal information in logs.

Secure development lifecycle

Review assumptions during architecture, inspect changes during implementation and validate critical behavior before deployment. Threat models should evolve with new integrations.

Incident response philosophy

Investigate reports, contain affected access, preserve relevant evidence and communicate appropriately. Report suspected issues through the contact page without including passwords or sensitive records.
