Care Identity Service for end user organisations
How health and social care organisations should prepare to start using Care Identity Service, including how to choose which authenticators to allow their clinical staff to use to log in, and how to get Registration Authority support.
Overview
Care Identity Service (CIS) is a national sign in (authentication) service that allows health and social care workers to access the systems they need securely.
If your organisation uses NHS or commercial software applications that are CIS-enabled, you'll need to set up your organisation to support CIS.
There are 3 activities you'll need to do:
- find a Registration Authority
- choose which authenticator(s) you’ll support
- train your technical support staff
Choose authenticators
Authenticators are the different methods you can use to sign in using CIS.
Your choice of authenticators is limited by which applications you use:
- some applications use our legacy CIS1 product and only support smartcards via HSCN
- some applications use CIS2, need assurance level AAL3 (‘very high’), and are limited to using our strongest authenticators
- some applications use CIS2, only need assurance level AAL2 ('high'), and can be used with all our authenticators
Some authenticators also need special hardware or software, which you’ll need to buy or install.
For more details, see Care Identity Service authenticators.
Train your technical support staff
CIS has specific hardware and software requirements, so you’ll need to train your technical support team to do things like:
- set up a workstation
- troubleshoot issues
- keep up to date with any changes to hardware and software requirements
This applies whether your IT support team are in-house or outsourced.
For more details, see our online guidance for technical support staff.
