## Security and Privacy

### Security and Privacy

When implementing Clinical Note Document (CND), implementers need to be aware of FHIR security and safety considerations and take appropriate measures to protect information privacy and prevent exploitation by malicious actors. In particular, implementers are advised to review:

* [FHIR Security Considerations](https://hl7.org/fhir/R4/security.html)
* [FHIR Implementer Safety Checklist](https://hl7.org/fhir/R4/safety.html)
* [AU Core Security and Privacy](https://build.fhir.org/ig/hl7au/au-fhir-core/security.html)

Implementers of Clinical Note Document need to be aware of their obligations regarding security, privacy, and consent in Australia.

For CND, specific security requirements include:

* Systems **SHOULD** conform to [FHIR Communications Security](https://hl7.org/fhir/R4/security.html#http) requirements.
* Systems **SHALL** use TLS version 1.2 or higher for data exchange.
* Systems **SHOULD** use TLS version 1.3 for data exchange.
* Systems **SHOULD** use the Australian Cyber Security Centre (ACSC) [TLS configuration guidelines](https://www.cyber.gov.au/resources-business-and-government/maintaining-devices-and-systems/system-hardening-and-administration/web-hardening/implementing-certificates-tls-https-and-opportunistic-tls) that include recommendations for configuring protocol features and acceptable cipher suites when implementing TLS.
