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.
Abstract-Text-based passwords, despite their well-known drawbacks, remain the dominant user authentication scheme implemented. Graphical password systems, based on visual information such as the recognition of photographs and / or pictures, have emerged as a promising alternative to the aggregate reliance on text passwords. Nevertheless, despite the advantages offered they have not been widely used in practice since many open issues need to be resolved. In this paper we propose a novel graphical password scheme, NAVI, where the credentials of the user are his username and a password formulated by drawing a route on a predefined map. We analyze the strength of the password generated by this scheme and present a prototype implementation in order to illustrate the feasibility of our proposal. Finally, we discuss NAVI's security features and compare it with existing graphical password schemes as well as text-based passwords in terms of key security features, such aspassword keyspace, dictionary attacks and guessing attacks. The proposed scheme appears to have the same or better performance in the majority of the security features examined.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
