Keep this document to one review outcome: Withdraw airport access immediately and tightly control temporary credentials. Only the official source and traced locations below supply facts. Confirm applicability before acting.

\n

Source fact:

\n

The official 49 CFR 1542.207 — Airport Security from Transportation Security Administration via eCFR supports the following bounded statements:

\n\n

These statements are the factual basis for this document. Do not extend them into a broader assurance. Review credentials, readers, controllers, panels, door hardware, access decisions, monitoring, and life-safety interfaces only where the source and recorded environment align.

\n

What the source does not establish

\n

Applies only to airport operators, tenants, personnel, and areas covered by 49 CFR part 1542 and the cited section. Confirm the TSA-approved security program and current directives; this is not legal advice or a universal access-control standard. Do not read the source as proof of implementation or permission to change production. Its guidance remains conditional on identity sources, DNS where used, time, networks, power, fire systems, monitoring, and authorized operators and the environment’s recorded constraints.

\n

Applicability questions

\n\n

DSE recommendation:

\n

DSE recommends using the cited source as the evidence anchor for this decision. Start with applicability, then compare the observed state with the cited source. Record the source location, examined part of credentials, readers, controllers, panels, door hardware, access decisions, monitoring, and life-safety interfaces, observed and expected states, owner, and reason for deviation.

\n

Translate the conclusion into change control only after documenting dependencies, impact, test method, expected signals, failure signals, and restoration steps. Include identity sources, DNS where used, time, networks, power, fire systems, monitoring, and authorized operators, while excluding secrets and sensitive personal or topology data from ordinary tickets.

\n

Verification and evidence

\n

A reviewer should be able to retrace the decision from 49 CFR 1542.207(a)(2), read with 49 CFR 1542.207(a) (eCFR anchor p-1542.207(a)(2)); 49 CFR 1542.207(d)(3), read with 49 CFR 1542.207(d) (eCFR anchor p-1542.207(d)(3)) through approved configuration exports, access-event tests, controller state, door inspections, alarm handling, and exception records. Record what was collected, where, when, by whom, and which system or role it represents.

\n

Keep before-state evidence, approval, test or change result, exceptions, and after-state evidence together. Use an approved lab, window, or nonproduction path for risky tests. Set a recheck trigger for version, architecture, dependency, vendor, incident, or ownership change. A check proves only what was observed.
