Prevent and detect unauthorized entry into airport secured areas

Treat this document as a focused evidence review: Prevent and detect unauthorized entry into airport secured areas. Only the official source and traced locations below supply facts. Confirm applicability before acting.

Source fact:

The official 49 CFR 1542.201 — Airport Security from Transportation Security Administration via eCFR supports the following bounded statements:

• Under 49 CFR 1542, the rule requires that each airport operator required to establish a secured area prevent and detect the unauthorized entry, presence, and movement of individuals and ground vehicles into and within the secured area by doing the following: establish and carry out measures for controlling entry to secured areas of the airport in accordance with section 1542.207. The research record locates this support at 49 CFR 1542.201(b)(1), read with 49 CFR 1542.201(b) (eCFR anchor p-1542.201(b)(1)).
• Under 49 CFR 1542, the rule requires that each airport operator required to establish a secured area prevent and detect the unauthorized entry, presence, and movement of individuals and ground vehicles into and within the secured area by doing the following: train each individual before granting unescorted access to the secured area, as required in section 1542.213(b). The research record locates this support at 49 CFR 1542.201(b)(5), read with 49 CFR 1542.201(b) (eCFR anchor p-1542.201(b)(5)).

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.

What the source does not establish

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.

Applicability questions

• For source statement 1 at 49 CFR 1542.201(b)(1), read with 49 CFR 1542.201(b) (eCFR anchor p-1542.201(b)(1)), which observable configuration, record, or test can confirm applicability here?
• For source statement 2 at 49 CFR 1542.201(b)(5), read with 49 CFR 1542.201(b) (eCFR anchor p-1542.201(b)(5)), which observable configuration, record, or test can confirm applicability here?
• Which owner can attest to the recorded state of credentials, readers, controllers, panels, door hardware, access decisions, monitoring, and life-safety interfaces, including exceptions?
• What baseline for identity sources, DNS where used, time, networks, power, fire systems, monitoring, and authorized operators must accompany the source-specific observation?
• Which success, stop, and escalation criteria are written before testing begins?

DSE recommendation:

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.

Do not move from citation to production in one step. Pilot the decision where practical, observe agreed signals, retain a reversal point, and verify identity sources, DNS where used, time, networks, power, fire systems, monitoring, and authorized operators. Handle credentials, keys, recovery data, and personal information through approved secure channels.

Verification and evidence

A reviewer should be able to retrace the decision from 49 CFR 1542.201(b)(1), read with 49 CFR 1542.201(b) (eCFR anchor p-1542.201(b)(1)); 49 CFR 1542.201(b)(5), read with 49 CFR 1542.201(b) (eCFR anchor p-1542.201(b)(5)) 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.

Preserve both successful and failed observations, along with approval and rollback evidence. Avoid uncontrolled production experiments. Assign an expiry or event-driven recheck so the conclusion is not treated as permanent.
