Safety and Security <img alt="" src="" style="BORDER:0px solid;" /> and SecuritySafety and Security <p style="text-align:justify;">Safety and Security are wide, cross-cutting priorities  The Safety&Security competence manages all the phases where a  failure   of a system can appear, forecasting (fault forecasting), preventing  (fault prevention), mitigating (fault tolerance), identifying for solving (fault removal).  For each phase of the system life cycle from feasibility to disposal/reuse  The approaches are adapted   on the one hand according to the customer requirements,   on the other hand  relating to the state of the art for technical issues and  possibly to the  compliance to prescriptive norms. Besides typical safety and vulnerability assessment to drive system requirements , independent verification and validation can be applied to projects assuring functional requirements compliance as well as  required QoS attributes.</p><p style="text-align:justify;">The unit is in charge of:</p><blockquote dir="ltr" style="margin-right:0px;"><p>1) supporting internal (CIRA) projects and  external projects by: </p><ul><li>risk assessment and impact analysis for new system concepts and/or new technologies  (verus cost efficiency,environment, safety, security,social acceptance,…);<br></li><li>RAMSS (reliability, availability, maintainability, safety and security)analysis: system safety assessment, risk analysis, independent verification and validation, SWAT analysis, FMECA, Fault tree/event tree analysis,…<br></li><li>definition and implementation  (agreed with: ENAC, EASA) certification strategy and related steps (PTF, DO compliance assurance,…airworthiness…).<br></li><li>definition and implementation of approaches  for QoS compliance (cost efficiency, environment, safety, security,social acceptance,…)<br></li><li>definition,application, validation of methodologies  to analyze research impact (safety, security, competitiveness, cost efficiency, , public acceptance….)<br></li></ul><p>2) methods and solutions  on formal methods, risks due to interdependence and unexpected events, liability allocation, real time risk management, Integrated System Health Management (ISHM), Mission Management paradigms, Systems Interoperability.</p></blockquote><p>The Unit collaborates with  national and international entities: universities, EREA Research centers, Eurocontrol, Airbus, Thales, civil Aviation Authorities (Enac,Enav, CAAUK, EASA),airports within European funded initiatives, with masters and training activities, in dissemination initiatives and as participant in international organizations: GARTEUR.
