# Train maritime-facility security personnel for assigned duties and changing threat levels > Use 33 CFR 105.210 -- Maritime Security: Facilities to review this narrow operational decision without extending the source beyond its stated scope. - Canonical URL: https://update.dsesecurity.com/updates/train-maritime-facility-security-personnel-for-assigned-duties-and-changing-threat-levels/ - Publisher: Detection Systems & Engineering (DSE Security) - Author: DSE Security Editorial Team - Published: 2026-08-27T12:11:20+00:00 - Modified: 2026-08-27T13:09:37+00:00 - Last reviewed by DSE: 2026-08-26 - Resource type: Briefing - DSE priority: Advisory - Topics: Access Control, Cybersecurity, Video Surveillance - Reading time: 3 minutes ## What you need to know Use 33 CFR 105.210 -- Maritime Security: Facilities to review this narrow operational decision without extending the source beyond its stated scope. ## Potentially affected Teams, systems, services, or facilities within the stated scope of 33 CFR 105.210 -- Maritime Security: Facilities ## DSE recommendation Compare the observed state with the cited official source, document applicability and exceptions, and test any approved change with rollback safeguards. ## Article Use this document to resolve one bounded operational decision: Train maritime-facility security personnel for assigned duties and changing threat levels. Only the official source and traced locations below supply facts. Confirm applicability before acting. ## Source fact: The official [33 CFR 105.210 — Maritime Security: Facilities](https://www.ecfr.gov/current/title-33/section-105.210) from U.S. Coast Guard via eCFR supports the following bounded statements: - Under 33 CFR 105, facility personnel responsible for security duties must maintain a TWIC, and must have knowledge, through training or equivalent job experience, in the following, as appropriate: the meaning and the consequential requirements of the different MARSEC Levels. The research record locates this support at 33 CFR 105.210(m), read with the unnumbered introductory paragraph of 33 CFR 105.210 (eCFR anchor p-105.210(m)). - Under 33 CFR 105, facility personnel responsible for security duties must maintain a TWIC, and must have knowledge, through training or equivalent job experience, in the following, as appropriate: crowd management and control techniques. The research record locates this support at 33 CFR 105.210(e), read with the unnumbered introductory paragraph of 33 CFR 105.210 (eCFR anchor p-105.210(e)). Only the traced statements above are asserted as source facts. Apply the review to access control, video, intrusion detection, communications, supporting facilities, operators, and documented response paths after confirming that the source and deployed context match. ## 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, 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. ## Applicability questions - For source statement 1 at 33 CFR 105.210(m), read with the unnumbered introductory paragraph of 33 CFR 105.210 (eCFR anchor p-105.210(m)), which observable configuration, record, or test can confirm applicability here? - For source statement 2 at 33 CFR 105.210(e), read with the unnumbered introductory paragraph of 33 CFR 105.210 (eCFR anchor p-105.210(e)), 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. Begin by recording scope and current state before deciding whether a change is warranted. 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. If the review warrants change, use a bounded implementation with prerequisites, test population, monitoring, abort criteria, and a rehearsed reversal. Sequence checks for identity, Windows DNS where used, time, networks, power, life-safety systems, vendors, and monitoring personnel and sanitize protected material before retention. ## Verification and evidence Tie each conclusion back to 33 CFR 105.210(m), read with the unnumbered introductory paragraph of 33 CFR 105.210 (eCFR anchor p-105.210(m)); 33 CFR 105.210(e), read with the unnumbered introductory paragraph of 33 CFR 105.210 (eCFR anchor p-105.210(e)) and to observable material such as asset and firmware inventories, configuration exports, event tests, inspections, alarm response records, and maintenance findings. Preserve provenance and stable identifiers without copying secrets into the evidence set. 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. ## Official references - [33 CFR 105.210 — Maritime Security: Facilities](https://www.ecfr.gov/current/title-33/section-105.210) — U.S. Coast Guard via eCFR ## Primary reference - Name: 33 CFR 105.210 -- Maritime Security: Facilities - Authority: www.ecfr.gov - URL: https://www.ecfr.gov/current/title-33/section-105.210 - Source publication date: Not stated by the source ## Citation and use Preferred citation: “Train maritime-facility security personnel for assigned duties and changing threat levels,” DSE Security, https://update.dsesecurity.com/updates/train-maritime-facility-security-personnel-for-assigned-duties-and-changing-threat-levels/ Publishing principles: https://update.dsesecurity.com/updates/dse-updates-editorial-methodology/ Usage and citation policy: https://update.dsesecurity.com/usage/ Copyright © 2026 Detection Systems & Engineering.
