Shared digital services need clear ownership even when several organisations depend on the same infrastructure. An audit can follow responsibilities and decisions without assuming the technical cause of a historical incident.
Questions to follow in an audit
- Which organisation owns each service and information risk?
- How are access changes approved across the participating teams?
- How are incidents communicated to the affected organisations?
Connect the records with practice
Trace one shared service through its agreement, named responsibilities, access review and evidence from an incident exercise.
These are illustrative audit trails, not findings about a named organisation, technical instructions or a guarantee of a particular result. The appropriate evidence depends on the activities, risks and agreed scope. The organisation remains responsible for its operations and legal obligations.
