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. 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.\nApplicability questions\n\nFor source statement 1 at 33 CFR 105.300(a) (eCFR anchor p-105.300(a)), which observable configuration, record, or test can confirm applicability here?\nFor source statement 2 at 33 CFR 105.300(d)(7), read with 33 CFR 105.300(d) (eCFR anchor p-105.300(d)(7)), 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. Start with applicability, then compare the observed state with the cited source. 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.\nDo not move from citation to production in one step. Pilot the decision where practical, observe agreed signals, retain a reversal point, and verify identity, Windows DNS where used, time, networks, power, life-safety systems, vendors, and monitoring personnel. Handle credentials, keys, recovery data, and personal information through approved secure channels.\nVerification and evidence\nA reviewer should be able to retrace the decision from 33 CFR 105.300(a) (eCFR anchor p-105.300(a)); 33 CFR 105.300(d)(7), read with 33 CFR 105.300(d) (eCFR anchor p-105.300(d)(7)) through asset and firmware inventories, configuration exports, event tests, inspections, alarm response records, and maintenance findings. Record what was collected, where, when, by whom, and which system or role it represents.\nPreserve 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.\nOfficial references\n\n33 CFR 105.300 — Maritime Security: Facilities — U.S. Coast Guard via eCFR",
