- Improved Resilience of Interdependent Critical Infrastructures via on-line Alerting SystemPublication . Capodieci, Paolo; Diblasi, Stefano; Ciancamerla, Ester; Minichino, Michele; Foglietta, Chiara; Lefevre, Davide; Oliva, Gabriele; Panzieri, Stefano; Setola, Roberto; De Porcellinis, Stefano; Delli Priscoli, Francesco; Castrucci, Marco; Suraci, Vincenzo; Lev, Leonid; Shneck, Yosi; Khadraoui, Djamel; Aubert, Jocelyn; Iassinovski, Serguei; Jiang, Jianmin; Simoes, Paulo; Caldeira, Filipe; Spronska, Agnieszka; Harpes, Carlo; Aubigny, MatthieuThis paper illustrates the activities under development within the FP7 EU MICIE project. The project is devoted to design and implement an on-line alerting system, able to evaluate, in real time, the level of risk of interdependent Critical Infrastructures (CIs). Such a risk is generated by undesired events and by the high level of interconnection of the different infrastructures. Heterogeneous models are under development to perform short term predictions of the Quality of Service (QoS) of each CI according to the QoS of the others, to the level of interdependency among the Infrastructures, and according to the undesired events identified in the reference scenario.
- Policy Based and Trust Management for Critical Infrastructure ProtectionPublication . Caldeira, Filipe; Monteiro, Edmundo; Simões, PauloCritical infrastructure (CI) services are consumed by the society constantly and we expect them to be available 24 hours a day. A common definition is that CIs are so vital to our society that a disruption or destruction would have a severe impact on the social well-being and the economy on a national and an international level. CIs can be mutually dependent on each other and a failure in one infrastructure can cascade to another interdependent infrastructure to cause service disruptions. Methods to better assess and monitor CIs and their interdependencies in order to predict possible risks have to be developed. This work addresses the problem of the quality of information exchanged among interconnected CI, the quality of the relationship in terms of trust and security and the use of Trust and Reputation management along with the Policy Based Management paradigm is the proposed solution to be applied at the CI interconnection points for information exchange.
- Trust and Reputation for Information Exchange in Critical InfrastructuresPublication . Caldeira, Filipe; Monteiro, Edmundo; Simoes, PauloToday’s Critical Infrastructures (CI) are highly interdependent in order to deliver their services with the required level of quality and availability. Information exchange among interdependent CI plays a major role in CI protection and risk prevention for interconnected CI were cascading effects might occur because of their interdependencies. This paper addresses the problem of the quality of information exchanged among interconnected CI and also the quality of the relationship in terms of trust and security. The use of trust and reputation indicators associated with the information exchange is the proposed solution. The proposed solution is being applied to information exchange among interconnected CI in scope of the European FP7 MICIE project, in order to improve information accuracy and to protect each CI from using inconsistent and non trustable information about critical events.
- Trust and Reputation Management for Critical Infrastructure ProtectionPublication . Caldeira, Filipe; Monteiro, Edmundo; Simoes, PauloToday’s Critical Infrastructures (CI) depend of Information and Communication Technologies (ICT) to deliver their services with the required level of quality and availability. ICT security plays a major role in CI protection and risk prevention for single and also for interconnected CIs were cascading effects might occur because of the interdependencies that exist among different CIs. This paper addresses the problem of ICT security in interconnected CIs. Trust and reputation management using the Policy Based Management paradigm is the proposed solution to be applied at the CI interconnection points for information exchange. The proposed solution is being applied to the Security Mediation Gateway being developed in the European FP7 MICIE project, to allow for information exchange among interconnected CIs.
- Trust based interdependency weighting for on-line risk monitoring in interdependent critical infrastructuresPublication . Caldeira, Filipe; Schaberreiter, Thomas; Monteiro, Edmundo; Jocelyn, Aubert; Simoes, Paulo; Khadraoui, DjamelCritical infrastructure (CI) services are constantly consumed by the society and are expected to be available 24 hours a day. A common definition states that CIs are so vital to our society that a disruption or destruction would have a severe impact on the social well-being and the economy nationally and internationally. CI sectors include, amongst others, the electricity, telecommunication, air traffic and transport sectors. CIs can be mutually dependent on each other and a failure in one CI can cascade to another dependent or interdependent CI to cause service disruptions. Methods to better assess and monitor CIs and their dependencies in order to predict possible risks have to be developed. Information about the current risk in a service provided by a CI can contribute not only to increase CI security, but also to increase the confidence of consumers and CIs that depend on this service. In this paper, a previous work on CI security modelling is extended. A trust based component is added to the security model as a means to improve its accuracy and its resilience to inconsistent information provided by dependent CIs allowing to evaluate the correctness of information received from those dependencies.
