Use this document to connect an official requirement or behavior to observable evidence: Document vulnerabilities, countermeasures, and constraints in the Facility Security Assessment. Only the official source and traced locations below supply facts. Confirm applicability before acting.

\n

Source fact:

\n

The official 33 CFR 105.305 — Maritime Security: Facilities from U.S. Coast Guard via eCFR supports the following bounded statements:

\n\n

These statements are the factual basis for this document. Do not extend them into a broader assurance. Review access control, video, intrusion detection, communications, supporting facilities, operators, and documented response paths only where the source and recorded environment align.

\n

What the source does not establish

\n

Applies only to facilities within 33 CFR part 105 and the cited section. 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.

\n

Applicability questions

\n\n

DSE recommendation:

\n

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 access control, video, intrusion detection, communications, supporting facilities, operators, and documented response paths, observed and expected states, owner, and reason for deviation.

\n

For 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.

\n

Verification and evidence

\n

A reviewer should be able to retrace the decision from 33 CFR 105.305(a)(9), read with 33 CFR 105.305(a) (eCFR anchor p-105.305(a)(9)); 33 CFR 105.305(a)(7), read with 33 CFR 105.305(a) (eCFR anchor p-105.305(a)(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.

\n

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.
