1 Technical Description

UniDesk is an ITIL based shared service. It is available using Shibboleth over the web for Higher and

Further Education. The service includes:

A Service Desk using TOPdesk software

Self service incident logging and knowledge management

Integrated ITIL compliant Incident, Problem, Change and Release processes

The service is hosted at Edinburgh but provides service management to all participating organisations, via

a web interface. The user interface does not require any software components to be installed by users of the

system and delivers excellent cross-browser compatibility.

Access to the software is facilitated via Shibboleth, with federated authentication at each site. Each

institution’s service is registered as a service provider with the UK Federation and makes use of the already-

existing shibboleth identity providers at each institution.

The software is installed in a virtualised environment, with each server having a Veeam replica residing in

a different physical location (live only). Failover to the secondary site is manual with the replicas being

taken nightly. The service uses a SQL Server database back-end; which has been configured as a mirror

across 2 sites.

UniDesk application software uses a built in web server which includes Shibboleth 2.x for webhosting

Note for point 1, 4: for tdeskapp* servers there is no cold standby server. The application servers are now

11 Resilience Measures

A mirrored pair of SQL Server servers in High Safety configuration is used. Manual intervention is required

to connect the database to the secondary SQL server database as automatic failover is not supported by

Topdesk.

15 Security Considerations

Access to Unidesk is made using HTTPS. Connections to external institutions for user data are carried out

over an encrypted channel (SFTP) to comply with Data Protection Legislation.

16 Authentication and Authorisation

Authentication is facilitated via shibboleth. Each institution has a separate install of Topdesk that uses

separate Service Provider (SP) registered with the UKFederation.

The eduPersonPrincipalName (EPPN) attribute requires to be released by the institutions Identity Provider

(IdP). The Topdesk application performs authorisation of the user based on the value of this attribute (e.g

[email protected])

17 Load Testing

Load testing has been carried out by Topdesk against Topdesk version 5. The results of these load tests

have been used to determine the memory configuration. No internal load testing has been performed with

version 5.

18 Interfaces and Dependencies

The University of Edinburgh feed of customer data is made using HTTPS connections to IDM web services.

Customer data from partners and member institutions is transferred using SFTP. In the event of

unavailability of these interfaces the data from the previous successful download remains within Unidesk.

Outgoing email is send via bulkmailrelay.ucs.ed.ac.uk, in the case of non-Edinburgh installations the email

will be send via the external institutions mail infrastructure. The configuration to perform this forwarding

is configured in the mailrelay infrastructure by IS ITI Unix Team.
