Senior Information Risk Owners 

A Senior Information Risk Owner (SIRO) is an Executive Director or member of the Senior Management Board of an organisation with overall responsibility for an organisation's information risk policy.

The SIRO is accountable and responsible for information risk across the organisation. They ensure that everyone is aware of their personal responsibility to exercise good judgement, and to safeguard and share information appropriately.

A SIRO is responsible for user access into Systems and Service Delivery (SSD) systems and this is done by submitting a Data User Certificate (DUC) via the exeter helpdesk.  The ODS Team will process the form, when sign off has been verified, and set up the user account on the Open Exeter system.  There is only one registered SIRO per organisation, however they can delegate responsibilty of user access sign-off to an Information Asset Owner (IAO).

Information Asset Owner

The Information Asset Owner (IAO) will be a senior member of staff who is the nominated owner for one or more identified information assets of the organisation. IAOs will support the organisation's SIRO in their overall information risk management function as defined in the organisation's policy. 

The IAO nomination form must be sent by the registered SIRO from the SIRO's email account. There is no limit to the number of IAO's a SIRO can nominate within their organisation.
