How do I decide whether cloud evidence needs urgent action?¶

Cloud evidence needs urgent action where relevant records are volatile, the account is actively compromised or delay could cause loss, harm or missed opportunity.

Evidential caution: that urgency depends only on the seriousness of the offence.

What this means¶

A recent low-level event may require quick preservation because the provider retains logs for only a short period.

An active compromise may require immediate containment, but containment itself can destroy useful session or token evidence.

Assess four things.

What evidence may disappear?

What harm may continue?

What action could preserve the evidence?

What action could alter or destroy it?

Where lawful and proportionate, preserve targeted records early.

Equally, do not make intrusive or irreversible changes without understanding their effect.

Urgency should be reassessed as new evidence arrives. A line that initially required preservation only may later justify acquisition, containment or specialist intervention.

Where the risk concerns ongoing access rather than evidence loss alone, identify who is responsible for containment and who is preserving records. Those functions may need to proceed in parallel under one documented plan.

What to check or do next¶

• Identify short-lived login, session, token, deleted-item, alert and audit records.
• Check whether the account may be closed, data deleted, devices synchronised or policies executed automatically.
• If containment is necessary, document the state first where operationally possible and coordinate with specialists.
• Do not delay preservation while trying to resolve every legal, technical or jurisdictional detail of full acquisition.
• Record the urgency assessment, action taken, owner and review point.
