Ensure that log data can only be routed to sink or export destinations inside the organisation's defined trust perimeter, so that a misconfigured or compromised sink cannot deliver logs to an external party. Routing logs to a sink is not data replication, so this control is distinct from core CN10.

| CCC.Logging.TH02 | Log Data is Transferred Outside the Trust Boundary | Sensitive log data, including PII, financial transaction details, or system vulnerabilities, may be exfiltrated through the query or API interfaces by a compromised or over-privileged account, or routed out by a sink configured to deliver logs to a destination outside the trusted boundary. Log data leaves the organisation's control, compromising its confidentiality. |
