Maritime security jobs are positions in which you provide onboard security to protect a commercial vessel and its crew from external threats, such as sea piracy and conflict when operating along contested or disputed shipping lanes. Other maritime security jobs include jobs in the Coast Guard or other border defense organizations. In these careers, you are responsible for securing ports and maritime monuments, such as the Statue of Liberty or other offshore facilities, and policing marine smuggling. Although the duties of these different jobs vary, your responsibilities in each have significant overlap.
