What you’ll learn

  1. Don't let the vendor write itBound the incident, build a sourced timeline, and classify findings before accepting a vendor summary.A usable improvement review starts with scope, evidence, and four kinds of finding — not a patch note.
  2. Change the path the incident usedTest the live vendor boundary, access, CBP notice clock, and customs continuity against observed facts.The broker owns the 72-hour SOC duty; downtime is case by case; a ticket is not proof of access.
  3. Close only on a changed stateAssign testable actions, write checkable vendor duties, verify reconnection evidence, and record residual risk.CBP reconnects ACE on a third-party investigation summary; leftover uncertainty needs an owner and a trigger.

Questions this course answers

Which statement best describes a useful improvement finding?

Separating event, conditions, failed controls, and evidence limits leads to a proportionate, testable action.

Put these vendor-improvement actions in a defensible order.

A bounded evidence review supports targeted action, testing, and an owned closeout decision.

Within how many hours of discovering a known breach of customs-business records must a broker electronically notify CBP SOC?

19 CFR 111.21(b) requires electronic notice to CBP SOC within 72 hours of discovery, including known compromised importer identification numbers. Additional known numbers follow within ten business days.

Match each improvement artifact to the question it answers.

Distinct artifacts keep facts, scope, action, testing, and risk decisions from being confused.

Why is a completed corrective-action ticket not enough to close a vendor-breach improvement review?

CBP reconnects ACE on a documented third-party investigation summary, not a vendor patch note. NIST treats lessons as Identify work that should feed the next controls, not a closed ticket.
