Confirm Coast Guard jurisdiction, the approved Facility Security Plan, the current MARSEC level, and any approved alternatives; this is not legal advice or a universal facility-design standard. No current deployment state or change approval follows from the source alone. Validate identity, Windows DNS where used, time, networks, power, life-safety systems, vendors, and monitoring personnel, and treat examples or options as conditional inputs rather than defaults.\nApplicability questions\n\nFor source statement 1 at 33 CFR 105.253(a)(3), read with 33 CFR 105.253(a) (eCFR anchor p-105.253(a)(3)), which observable configuration, record, or test can confirm applicability here?\nFor source statement 2 at 33 CFR 105.253(b) (eCFR anchor p-105.253(b)), which observable configuration, record, or test can confirm applicability here?\nWhich owner can attest to the recorded state of access control, video, intrusion detection, communications, supporting facilities, operators, and documented response paths, including exceptions?\nWhat baseline for identity, Windows DNS where used, time, networks, power, life-safety systems, vendors, and monitoring personnel must accompany the source-specific observation?\nWhich success, stop, and escalation criteria are written before testing begins?\n\nDSE recommendation:\nDSE recommends using the cited source as the evidence anchor for this decision. Anchor the review in the cited section and keep observation separate from interpretation. 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.\nFor an approved change, define prerequisites, a limited test path, success and stop conditions, monitoring, and rollback. Check identity, Windows DNS where used, time, networks, power, life-safety systems, vendors, and monitoring personnel in design order. Protect credentials, keys, recovery material, personal data, and sensitive topology in evidence.\nVerification and evidence\nEvidence should let another reviewer reproduce this decision. Retain observations beside the traced locations 33 CFR 105.253(a)(3), read with 33 CFR 105.253(a) (eCFR anchor p-105.253(a)(3)); 33 CFR 105.253(b) (eCFR anchor p-105.253(b)). Favor asset and firmware inventories, configuration exports, event tests, inspections, alarm response records, and maintenance findings, linked to stable identifiers, time, and operator.\nKeep 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.\nOfficial references\n\n33 CFR 105.253 — Maritime Security: Facilities — U.S. Coast Guard via eCFR",
