ISPS is an abbreviation for the International Ship and Port Facility Security Code. It is a set of measures that is intended to increase maritime security in ports and on ships. The IMO (International Maritime Organization) operating under the authority of the UN has advocated the Code.
The ISPS Code is divided into security levels. They fluctuate depending on the situation and possible relevant threats. Each country's police authorities determine the security levels, and thus, they may alter from one port to the next.
