Executive summary

What you need to know

Use 49 CFR 1542.203 -- Airport Security to review this narrow operational decision without extending the source beyond its stated scope.

Potentially affected

Teams, systems, services, or facilities within the stated scope of 49 CFR 1542.203 -- Airport Security

DSE recommendation

Compare the observed state with the cited official source, document applicability and exceptions, and test any approved change with rollback safeguards.

Frame this document as a source-led configuration and assurance check: Control and monitor entry into the airport air operations area. Only the official source and traced locations below supply facts. Confirm applicability before acting.

Source fact:

The official 49 CFR 1542.203 — 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 an AOA prevent and detect the unauthorized entry, presence, and movement of individuals and ground vehicles into or within the AOA by doing the following: provide security information as described in section 1542.213(c) to each individual with unescorted access to the AOA. The research record locates this support at 49 CFR 1542.203(b)(3), read with 49 CFR 1542.203(b) (eCFR anchor p-1542.203(b)(3)).
  • Under 49 CFR 1542, the rule requires that each airport operator required to establish an AOA prevent and detect the unauthorized entry, presence, and movement of individuals and ground vehicles into or within the AOA by doing the following: provide for detection of, and response to, each unauthorized presence or movement in, or attempted entry to, the AOA by an individual whose access is not authorized in accordance with its security program. The research record locates this support at 49 CFR 1542.203(b)(2), read with 49 CFR 1542.203(b) (eCFR anchor p-1542.203(b)(2)).

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 1542.203(b)(3), read with 49 CFR 1542.203(b) (eCFR anchor p-1542.203(b)(3)), which observable configuration, record, or test can confirm applicability here?
  • For source statement 2 at 49 CFR 1542.203(b)(2), read with 49 CFR 1542.203(b) (eCFR anchor p-1542.203(b)(2)), 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.

For an approved change, define prerequisites, a limited test path, success and stop conditions, monitoring, and rollback. Check identity sources, DNS where used, time, networks, power, fire systems, monitoring, and authorized operators in design order. Protect credentials, keys, recovery material, personal data, and sensitive topology in evidence.

Verification and evidence

A reviewer should be able to retrace the decision from 49 CFR 1542.203(b)(3), read with 49 CFR 1542.203(b) (eCFR anchor p-1542.203(b)(3)); 49 CFR 1542.203(b)(2), read with 49 CFR 1542.203(b) (eCFR anchor p-1542.203(b)(2)) 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.

Close the review only when the evidence, exception handling, resulting action, and after-state are linked. Schedule a new review after material technical, organizational, incident, or source changes; today’s observation is not a continuing guarantee.
