Basic Division Officer Course (BDOC) Maritime Warfare (MW) Practice Test

When a suspected cyberattack on navigation data occurs, safety and continuity of operations come first. The best response is to switch to backup navigation sources to maintain awareness and safe maneuvering, isolate the affected systems to prevent the breach from spreading, preserve evidence so investigators can determine what happened, notify command to bring in leadership and resources, and begin the cyber incident response process to coordinate containment, eradication, recovery, and lessons learned. This sequence protects lives and ships, keeps mission capability intact, and follows established BDOC procedures for cyber incidents.

Ignore the alert risks navigation safety; shutting down navigation permanently eliminates the ability to navigate and is not a controlled response. Replacing data with unverified information would corrupt navigation data and mislead operators, creating dangerous conditions.
