Infrastructure

Production

The PKB infrastructure is hosted by Carelink in the UK, a specialised Health and Social Care Network (HSCN) - formerly the N3 network - hosting provider. Carelink is one of a shortlist of hosting providers to be certified to the stringent ISO 27001 standard. All facilities are tier 4 data centres (Telehouse, Docklands and Equinix, Heathrow). Additionally, Carelink holds the following accreditations: ISO 20000, ISO 9001.


No data is processed outside of PKB’s core infrastructure, or by contractors or third parties. All data processing is completed and controlled in-house, additionally no data is processed outside of the HSCN network.


HSCN (N3) Sandbox

PKB provides a sandbox environment, hosted as above, for clients wishing to test without leaving the HSCN firewall.


Sandbox

PKB sandbox is hosted by Rackspace.


Backups

Nightly data backups are facilitated via CareLink through Asigra, these backups are fully encrypted with no unauthorised access to clinical data possible.


Data is encrypted to disk as above with a second layer applied by Asigra: 3DES 56bit with public and private keys stored separately. PKB employs RAID5 for our database servers, utilizing an array of SSD’s.


PKB makes use of CareLink’s hardware firewalls (Check Point FireWall-1, running version 77.30) to protect our infrastructure against attacks and unauthorized entry as well as system level firewalls.


Replication

PKB utilizes live asynchronous replication to a secondary server (mirroring) enabling point-in-time recovery.
