Make facility security response sustain critical operations and required reporting

Treat this document as a focused evidence review: Make facility security response sustain critical operations and required reporting. Only the official source and traced locations below supply facts. Confirm applicability before acting.

Source fact:

The official 33 CFR 105.280 — Maritime Security: Facilities from U.S. Coast Guard via eCFR supports the following bounded statements:

• Under 33 CFR 105, the rule requires that for each MARSEC Level, the facility owner or operator ensure the Facility Security Officer and facility security personnel are able to respond to security threats or breaches of security and maintain critical facility and vessel-to-facility interface operations. The research record locates this support at 33 CFR 105.280(a), read with the unnumbered introductory paragraph of 33 CFR 105.280 (eCFR anchor p-105.280(a)).
• Under 33 CFR 105, the rule requires that for each MARSEC Level, the facility owner or operator ensure the Facility Security Officer and facility security personnel are able to report security incidents as required in section 101.305 of this subchapter. The research record locates this support at 33 CFR 105.280(c), read with the unnumbered introductory paragraph of 33 CFR 105.280 (eCFR anchor p-105.280(c)).

Do not import neighboring assumptions into the source record. The supported task is a scoped comparison involving essential functions, upstream providers, recovery sequences, alternate work paths, and tested recovery objectives and the conditions the source actually describes.

What the source does not establish

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. No current deployment state or change approval follows from the source alone. Validate identity, DNS, communications, facilities, suppliers, and the people authorized to invoke recovery, and treat examples or options as conditional inputs rather than defaults.

Applicability questions

• For source statement 1 at 33 CFR 105.280(a), read with the unnumbered introductory paragraph of 33 CFR 105.280 (eCFR anchor p-105.280(a)), which observable configuration, record, or test can confirm applicability here?
• For source statement 2 at 33 CFR 105.280(c), read with the unnumbered introductory paragraph of 33 CFR 105.280 (eCFR anchor p-105.280(c)), which observable configuration, record, or test can confirm applicability here?
• Which owner can attest to the recorded state of essential functions, upstream providers, recovery sequences, alternate work paths, and tested recovery objectives, including exceptions?
• What baseline for identity, DNS, communications, facilities, suppliers, and the people authorized to invoke recovery 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 essential functions, upstream providers, recovery sequences, alternate work paths, and tested recovery objectives, observed and expected states, owner, and reason for deviation.

Translate the conclusion into change control only after documenting dependencies, impact, test method, expected signals, failure signals, and restoration steps. Include identity, DNS, communications, facilities, suppliers, and the people authorized to invoke recovery, while excluding secrets and sensitive personal or topology data from ordinary tickets.

Verification and evidence

Keep the source locations 33 CFR 105.280(a), read with the unnumbered introductory paragraph of 33 CFR 105.280 (eCFR anchor p-105.280(a)); 33 CFR 105.280(c), read with the unnumbered introductory paragraph of 33 CFR 105.280 (eCFR anchor p-105.280(c)) adjacent to the sanitized artifacts used for comparison. Prefer business-impact records, dependency maps, exercise results, recovery timings, and open corrective actions, with enough identity and timing data for an independent recheck.

Record the decision even when no change is made, including uncertainty and the next trigger. Use safe testing conditions for disruptive work, preserve rollback proof, and revisit the conclusion after relevant platform, dependency, vendor, or ownership changes.
