This document summarizes the International Ship and Port Facility Security (ISPS) Code, which establishes measures to enhance maritime security. It lays out regulations for ship and port facility security that are binding under the Safety of Life at Sea convention. The code requires vessels and ports to conduct security assessments, develop security plans, perform drills and exercises, and obtain related certificates. It also provides guidelines for setting security levels, access control, monitoring, training, and roles and responsibilities for ship crews, port facility personnel, and contracting governments. The goal is to enhance maritime security and deter threats to ships and port facilities engaged in international voyages.
