What evidence may support insider attribution?¶

Insider attribution should combine independent account, device, physical, communication and contextual evidence. Workplace access alone does not make the answer straightforward.

Test access, opportunity and control¶

Compare session logs, device IDs, schedules, physical access, files and searches, approvals, media, cloud, email, finance, witnesses and communications. Determine whether the person had authority, knowledge, opportunity, session control and a link to recipient or benefit.

Motive without access and access without personal control are insufficient. Coercion, compromise and automation remain alternatives.

Check independence of corroboration¶

Account use, device location and network address may all derive from one shared workstation and are not three independent facts. Evidential strength comes from genuinely different sources.

Formal assignment can differ from working practice where assistants, delegates or shared offices are involved. Test ownership against actual use and preserve conflicts rather than counting repeated versions of one event.
