Port Information and Communication Technology (PICT) systems offer a series of critical services rendering their effective security management an issue of vital importance. Existing regulation, standardization, and risk management methodologies do not adequately address the cyber threats the dependent environment of PICT systems is exposed to. In the SPort project, we identified and addressed these needs by proposing a collaborative environment offering customized security management services targeted at the unique needs of port authorities. The success of S-Port has been deployed in three commercial ports, so as to assist them in self managing security and risks. In this paper, we present the main objectives and core functionalities of S-Port environment, as well as the overall results of its assessment.
