Does a recorded event prove that a person caused it?¶

A recorded event proves that a system recorded activity or a state change. It does not automatically prove that a person directly caused it.

That distinction is fundamental to log interpretation.

Avoid this assumption: That every event associated with a user account represents a deliberate action by that user. It may not.

Events can be created by operating systems, applications, background services, scheduled tasks, scripts, APIs, security products and synchronisation processes. A user may have triggered the wider process without directly causing every downstream event.

An account name may appear because the process ran within that account’s session or security context. That does not establish that the account holder was present, understood the action or intended the result.

Some events do reflect direct interaction, such as a button press or command entered at a terminal. Even then, attribution requires evidence that the relevant person controlled the device, account or session at the time.

Investigators should identify what component created the event and what normally triggers it. Ask whether the action can occur automatically, remotely or through an existing session. Preserve process, session, request and correlation identifiers that may show how the event arose.

Correlate the event with authentication, device, application, network and communications evidence. Look for surrounding activity consistent with deliberate interaction rather than relying on the event label alone.

Use careful language. Describe what the system recorded before moving to an inference about who caused it. Make clear where the conclusion depends on correlation rather than direct observation.

Operational takeaway¶

A recorded event establishes system-observed activity, but personal causation requires evidence linking the event to a person’s control, interaction and intent rather than merely to an account or device.
