Define secured areas, access systems, law-enforcement support, and contingencies in the airport security program

Treat this document as a focused evidence review: Define secured areas, access systems, law-enforcement support, and contingencies in the airport security program. Only the official source and traced locations below supply facts. Confirm applicability before acting.

Source fact:

The official 49 CFR 1542.103 — Airport Security from Transportation Security Administration via eCFR supports the following bounded statements:

• Under 49 CFR 1542, an airport security program must describe the law-enforcement support used to comply with section 1542.215(a). The research record locates this support at 49 CFR 1542.103(a)(12), read with 49 CFR 1542.103(a) (eCFR anchor p-1542.103(a)(12)).
• Under 49 CFR 1542, an airport security program must describe sterile-area access controls used to comply with section 1542.207. The research record locates this support at 49 CFR 1542.103(a)(6)(iii), read with 49 CFR 1542.103(a)(6)|1542.103(a) (eCFR anchor p-1542.103(a)(6)(iii)).

Do not import neighboring assumptions into the source record. The supported task is a scoped comparison involving access control, video, intrusion detection, communications, supporting facilities, operators, and documented response paths and the conditions the source actually describes.

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. The citation is not a substitute for observed state, authorization, compliance evidence, or dependency health. Examine identity, Windows DNS where used, time, networks, power, life-safety systems, vendors, and monitoring personnel before translating the source into an operational decision.

Applicability questions

• For source statement 1 at 49 CFR 1542.103(a)(12), read with 49 CFR 1542.103(a) (eCFR anchor p-1542.103(a)(12)), which observable configuration, record, or test can confirm applicability here?
• For source statement 2 at 49 CFR 1542.103(a)(6)(iii), read with 49 CFR 1542.103(a)(6)|1542.103(a) (eCFR anchor p-1542.103(a)(6)(iii)), which observable configuration, record, or test can confirm applicability here?
• Which owner can attest to the recorded state of access control, video, intrusion detection, communications, supporting facilities, operators, and documented response paths, including exceptions?
• What baseline for identity, Windows DNS where used, time, networks, power, life-safety systems, vendors, and monitoring personnel 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. Use a two-person review for the source interpretation and the resulting operational decision. Record the source location, examined part of access control, video, intrusion detection, communications, supporting facilities, operators, and documented response paths, observed and expected states, owner, and reason for deviation.

An implementation decision needs an owner, approved window, prechecks, observable outcome, stop authority, and rollback path. Validate identity, Windows DNS where used, time, networks, power, life-safety systems, vendors, and monitoring personnel before and after the test, and store only sanitized operational evidence.

Verification and evidence

Keep the source locations 49 CFR 1542.103(a)(12), read with 49 CFR 1542.103(a) (eCFR anchor p-1542.103(a)(12)); 49 CFR 1542.103(a)(6)(iii), read with 49 CFR 1542.103(a)(6)|1542.103(a) (eCFR anchor p-1542.103(a)(6)(iii)) adjacent to the sanitized artifacts used for comparison. Prefer asset and firmware inventories, configuration exports, event tests, inspections, alarm response records, and maintenance findings, with enough identity and timing data for an independent recheck.

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.
