Tip

This change only affects customers whom are connecting to our Hl7 API over the Public Internet, which is the minority. Majority of connections are made over HSCN.

New endpoints

We plan to introduce three new endpoints:

Deprecations

Motivations/Goals

We want to tighten our security. Efforts we make on this front include:

...

All new endpoints have WAF protection. Two out of the three new only accepts ciphers that are deemded as

Status
colourGreen
titlerecommeded
and
Status
colourGreen
titlesecure
by the industry, while the third provides backward compatilibity.

Better support clients in the clould

We offer mtls.hl7.uk.patientsknowbest.com to those customers who moved to the cloud and can’t use static IPs when accessing our services. It is also our prefered setup for new customers.

Identity is still derived from client credentials and not the client certificate. mTLS in this scenario is only used to replace IP allow listing.

Improve security

Customers, who have

  • up-to-date client software toosl that support to state of the art cipher suits,

  • have static IPs that we can allow-list and

  • can’t allocate budget to implement mTLS in short term

can move to no-mtls.hl7.uk.patientsknowbest.com.

Backward compatibilty

deprecated-ciphers.no-mtls.hl7.uk.patientsknowbest.com is intended for customers whom are on ore out of date software systems hence still using ciphers that are considered to be weak and cannot update their system in short term.

Note

We urge all our customers to get their systems up to date as it is a common best interest to exchange data as safely as possible.

Standard ports

Using standard ports will allow us to consolidate our server certificate management and fully automate the renewall process for all our endpoints.

Supported ciphers

my.patientsknowbest.com:7443 supports all ciphers in below table. The new endpoints are compared with this - now deprecated - endpoint.
