Cloud Services Technical Explainer

Could a file be created by an application or service account?¶

Yes. Software can create reports, exports, logs, backups, converted documents and other cloud objects under its own technical identity or under authority delegated by a user.

Identify the actor model¶

An application may use a user's delegated permission, so the resulting object appears inside that account. A service account may act under a separate non-human identity. A workflow can run when a schedule or another event triggers it.

The visible owner may be the folder owner or authorising user rather than the process that generated the content. Provider audit and API records may identify the application, service account, operation and job or request ID more accurately.

Generated content has a provenance chain¶

Ask what inputs the process used, which rules or template transformed them, when it ran and where it wrote the result. A generated spreadsheet, for example, may combine records from several systems and reflect extraction logic rather than a person's direct observation.

Configuration, ownership and change history can show who designed or altered the process. Trigger history may identify whether a person initiated this run or whether it executed automatically.

Do not confuse automation with unreliability¶

System-generated files may be valuable contemporaneous records. Their evidential meaning depends on the reliability and scope of the generating process. State that the application created the object, then address any human configuration, trigger or control separately.

Power Automate run RUN-204 uses service principal SP-88 to create daily-risk.csv, OneDrive object OBJ-9910, from SharePoint list snapshot LIST-44 and template version TPL-6. The report can reliably show what that configured process output at 02:01. To interpret its contents, preserve the input snapshot, query or transformation rules, workflow version and execution result - not merely the visible filename or owner.

A generated file inherits provenance from inputs, rules and execution

EstablishedThe chain can establish which retained inputs and rule version produced the identified output in this run.

Still openWhether the inputs were complete, the rules were valid and a particular person designed, triggered or adopted the result.

The next useful comparison is the output object and hash against the run log, application identity, API request, exact input snapshot, transformation version and configuration-change history.

Another linked device can also originate a cloud change through a client process, so device and application identifiers should remain attached to the event.

Current Microsoft application-identity example - checked 3 September 2026

Microsoft Entra currently records user, non-interactive user, service-principal and managed-identity sign-ins separately. Microsoft Graph activity logs can record HTTP requests received for a tenant and support correlation of requests made by a user or app with sign-in information. Availability depends on licensing and diagnostic configuration.

The point to remember

A cloud file may be produced by software rather than manually authored. Preserve the technical identity, inputs, rules and trigger so creation and human responsibility remain separate propositions.
