  1. “Exploiting Open Source Intelligence for Enhancing Social Participation: The Local Governance Case”, Miltiadis Kandias, Dimitris Gritzalis, Information Security & Critical Infrastructure Protection (INFOSEC) Laboratory Dept. of Informatics, Athens University of Economics & Business (AUEB), Greece
    15:30 – 16:00 / Session 1 / Room4 


    • The emergence of Web 2.0 and Online Social Networks has enabled individuals towards expressing themselves within their personal social networks. One of these individuals’ identities is that of the citizen’s, thus it is possible to gather and quantify their opinions under the prism of their desires and demands regarding local governance. So, such capabilities can be further utilized in order to facilitate the incessant and unmediated communication between the citizens and the local authorities.Local government institutions could gather and evaluate what citizens reveal online, in order to respond in a timely and fruitful manner. This opportunity materializes a bidirectional means of communication between local society and local authorities and a medium for participatory gover-nance which is able to meet citizens’ needs in a fast and reliable manner. To this end, the NEREUS experimental platform conducts data gathering and sentiment analysis from online sources, where citizens express their opinions, thus facilitating local government in understanding and acting bas-ed on citizens’ requests and needs.This way, local governance institutions are able to act in favor of the citizens according to their opinion. The data collection process is conducted by respecting each individual’s privacy and anonymity through an irreversible anonmization/pseudonymization layer. Then, the collected data is transformed to an analyzable form (greeklish is automatically transformed to Greek, in order to be adequately processed), and fed into an automated sentiment analysis system that extracts each post’s emotional placing (positive, negative, neutral). Finally, the generated results are visualized so as to facilitate the results interpretation by those in-charge for transforming social mandates to actions.According to the above, social gain is improved, as Internet and Data Science technologies are utilized in favor of local authorities’ efficiency and effectiveness, while fragments of direct demo-cracy are encapsulated within the current local governance paradigm. Indirect results of such in-novative initiatives may improve the social cohesion, minimize the social exclusion from the decision-making process, and maximize opportunities for engagement of the society in the local governance matters, thus leading to the reclamation of the commons in the local societies while keeping the barrier between online private and public sphere and respecting (digital) human rights
  2. “Immigration, smart borders and new technologies”, Alexandros Zavos, Institute of Immigration Policy,  Greece
    16:00 – 16:30 / Session 1 / Room4]


    • It is commonly accepted, that the migration flows from the sub-Saharian Africa and from Asia to Europe have become one of the hardest problems to solve in the global community. The escalation of the migration flows dictates the course of action towards the monitoring and recording of these movements, as the conventional means have proven  not to be sufficientEurope seems incapable of managing those migration flows both at the political and the technical level. It is estimated that this year, 400. 000 people will enter Europe’s borders through Greece and Italy. Recently we have observed contradictory actions from the   European Union member states concerning the Syrian Refugee flows, actions such as building fences, integrating policies by welcoming thousands of people and suspending the Schengen Treaty in order to avoid the entrance of these flows.Awareness that information and communication technologies have to be used and developed in order to improve the managing capabilities of this crisis has increased.  The adoption by the European Union of  the “Smart Borders” policy   has been also announced by the European Commissioner in charge. This policy provides a modern monitoring, registration and identification system of new entrants into the European Union within the Schengen Area.New technologies for border control present new financial opportunities which up to now have been by only a few companies, which have had the opportunity to amass considerable financial benefits. This presentation will focus on the migration flows, the current policies and the role new technologies can play.

  3. “Daedalus: Platform for Seeking and Providing Opportunities”, George Koukoulas, Peggy Karaviti, Unisystems SA, Greece
    16:30 – 17:00 / Session 1 / Room4


    • The crisis in the International community and to a much greater extent on the Mediterranean countries, leads many people in seeking new opportunities even outside territorial boundaries. In addition, the use of technological tools to seek the most appropriate opportunity and/or to provide opportunities has been increased.
      DAEDALUS is an innovative High-Tech Solution to deal with Labor Constraints in the Mediterranean Basin, operating through internet providing free services to everybody. It provides a cross-border network of young people, entrepreneurs, ICT companies, online business, regional and local employment associations. It constitutes a valuable pool of young people and professionals across the Mediterranean area. The offered services help to determine the current matching of market demand and supply needs across the various countries and regions participating in the Mediterranean Basin.
      The overall objective of the project is to address the needs of the young residents seeking employment or other career opportunities (such as academic career, investments, partnerships, etc.) in the labour markets of the Mediterranean Sea Basin by enhancing their business opportunities and matching their qualifications and skills with existing needs in neighboring countries. Daedalus operation is based on an updated database able to actively match the opportunities seeking from young people and professionals with opportunities openings from both the South and the North coasts of Mediterranean area, and even beyond the Mediterranean.
      Daedalus provides many innovative characteristics to its users;
      – Seekers may store various profiles (in up to five supported languages) to use for applying for different types of opportunities.
      – Opportunities Providers can use a complete management system for the announcement of the opportunities and the selection of the appropriate individuals, through an advanced matching “qualifications – prerequisites” mechanism.
      – Both Seekers and Opportunity providers can benefit from the Advisors’ articles, as well as from their answers to questions.
      – Finally yet importantly, through the Public Library the user can be informed for the Regulations and Legal Frameworks regarding employment and migration on the project’s participating countries.
      The Daedalus portal aims to involve both the private and the public sector to deal with the labour market constraints in the Mediterranean area, effectively contributing toward a wider integration between different Countries and cultures.
      Daedalus project is being financed by the European Union and the 2007-2013 ENPI CBC Mediterranean Sea Basin Programme for an amount of 1,745,472.60 million Euro (90%), and is being implemented by an international consortium consisting of 9 partners located in 6 Mediterranean countries (Cyprus, Greece, Italy, Lebanon, Palestine, Tunis).

  4. “ICT to Boost Employability and Enhance Social Cohesion” Petros Salichos, Nineta Polemi and Christos Douligeris, Department of Informatics, University of Piraeus
    17:00 – 17:30 / Session 2 / Room4


    • The changing face of the cyberspace is alternating the shape of the digital societal structure affecting all types of activities (e.g. employment seeking, integration of legal immigrants).
      The role of ICT has become essential in the fight against unemployment at national and EU level, since ICT accelerates the efforts of the unemployed youth, disadvantaged groups, minorities etc. to seek employment. The European modern digitalized society, in the threshold of globalization sets as one of the most important objectives of the European Commission (E.C), the facilitation of equal employment opportunities. Employability lies in the center of European ICT initiatives because deprivation of work is one of the most important factors leading to social exclusion. Information technology and the use of Internet can provide useful and powerful tools in today’s society and affect the way that modern Human Resource planning and improvement is achieved nowadays. Internet has also simplified innovations addressing to job seekers and employers and affected the way the Labor Market operates in various ways such as searching for a job, searching for an employee, the delivery of Labor services and the way that local Labor markets shape their demand. Research on this field is underlying the fact that online job search can shorten the time needed in order to find a job and provide better outcomes in the Labor market.
      The need to adopt automated procedures and integrate the available technological tools that can approach in a more holistic way the issue of employability and free movement have introduced many software tools at EU level that provide advising and employment eservices, information and statistical data for work, study abroad and generally cross-border commuting, opportunities, search services, job vacancies, the legislation framework and legal proceedings.

  5. “PACiNNO – a Platform for Academic Cooperation in Innovation”, Phivos Mylonas, Department of Informatics, Ionian University
    17:30 – 18:00 / Session 2 / Room4


    • The goal of PACiNNO is to establish a platform for cooperation in research and innovation covering the whole Adriatic region. Targeting both research institutions, policy makers and business entities, the project will help develop new bridges between the research and scientific activities, carried out at academic institutions, and the economic system, with specific reference to the technological needs of SMEs. More generally, PACiNNO is aimed at overcoming the main obstacles and barriers to the economic development of the Adriatic countries, fostering the competitiveness of their minor firms (both in the high-tech fields and in the traditional industries), and promoting the creation of innovative start-ups.
      To reach such ambitious goals, the project will capitalize on the several programs and initiatives already implemented in the Adriatic region by the EU, the national governments and the local stakeholders. PACiNNO will combine research activities with direct interventions in the local innovation systems.The active involvement and participation to the project initiative of the key innovation stakeholders (research centers, territorial bodies, science and technology parks, business incubators, financial investors, business units, multinational companies based in the region) is meant to create a regional innovation system supported by a permanent platform of collaboration, where private and public institutions can interact and integrate their efforts and resources to favor innovation outcomes across the region, even after the end of PACiNNO.

  6. “Building Training to Employment Pathways in Agriculture through competence-based ICT services”, Cleo Sgouropoulou, Department of Informatics, TEI of Athens
    18:00 – 18:30 / Session 2 / Room4

State of the art technologies in next generation data networks

Session Organizers: A. Bogris

  1. “Future Internet Space:Cloud-enabled IoT data management for Smart Farming, tracing and business request matching”, Sokratis Mparmpounakis, Research Associate in Self configuring autonomic networking and services Lab, Department of Informatics and Telecommunications, Univ. of Athens.
    11:00 – 11:30 / Session 3 / Room4


    • EU has invested a vast amount of money in building the main platforms for Future Internet in order to boost future internet applications. FISPACE has been a flagship project in the direction of building enablers for future internet IoT applications (e.g., for transportation, farming, logistics etc.) and respective mechanisms for cloud based data management, business process matching and IoT data aggregation. Enablers for data openness are also identified.

  2. “Optical interconnect technologies for exascale cloud datacenters”, Dimitris Apostolopoulos, Research Associate in Photonics Communications Research Laboratory, NTUA
    11:30 – 12:30 / Session 3 / Room4


    • The increasing deployment of optical technologies for rack-to-rack communication in current generation datacenter and HPC systems has so far led to faster and greener system implementations, but is not sufficient to sustain performance trends and contain energy consumption. Photonics have started to migrate into all levels of the interconnect hierarchy as an enabler of future datacenter architectures, in order to meet the rapidly growing demand on digital information transmission, capture, storage and processing. Motivated by recent breakthroughs and emerging technologies in optical interconnects and the evolution of datacenter architectures, this talk presents our work towards the development of a dynamic, scalable, optical network based, disaggregated datacenter architecture and supporting infrastructure.

  3. “In-Network Programmability for Next-Generation personal Cloud service support: The INPUT project”, Dr Constantinos Vassilakis, Senior Researcher, UBITECH
    12:00 – 12:30 / Session 3 / Room4


    • The need for cloud applications’ performance requirements meets the “softwarization” revolution that has been undertaken in the networking and telecom fields during the last few years. In this respect, Software Defined Networking (SDN) and Network Function Virtualization (NFV) are well known to be the best candidates for achieving the suitable levels of flexibility, upgradability and integration with IT services that are needed for supporting the aforementioned revolution in network architectures fitting in the Future Internet (FI). The INPUT Project aims to contribute to the evolution of the Internet “brain” beyond current limitations due to obsolete IP network paradigms, by moving cloud services much closer to end-users and smart-devices. This evolution will be accomplished by introducing intelligence and flexibility (“in-network” programmability) into network edge devices, and by enabling them to host cloud applications capable of cooperating with and of offloading corresponding applications residing in the users’ smart objects and in datacenters to realize innovative personal cloud services.

  4. “RAWFIE: Future Internet Experimentation Platform with Robotic Devices”, Prof. Stathes P. Hadjiefthymiades, Pervasive Computing Research Group, Department of Informatics and Telecommunications, Univ. of Athens.
    13:30 – 14:00 / Session 4 / Room4


    • The focus of this H2020 FIRE+ project is on Road-, Air- and Water- based Future Internet Experimentation. RAWFIE delivers a federation of unmanned vehicle testbeds for experimenting and assessing performance of different technologies in networking, sensing and mobile/autonomic application domains. The unmanned vehicle testbeds of RAWFIE host Unmanned Ground Vehicles (UGVs), Unmanned Aerial Vehicles (UAVs) and Unmanned Surface Vehicles (USVs). The set of RAWFIE partners will be supplemented through 2 open calls cycles.

  5. “Unification and orchestration of network functions in the data center of an operator by using commodity equipment”, George Agapiou, Head of Wireless Research Lab (WRL), OTE
    14:00 – 14:30 / Session 4 / Room4


    • UNIFY aims at creating a new architecture supporting the virtualization of telecom networks and their association with cloud computing technologies. The UNIFY network infrastructure will contribute to the improvement of the quality of experience enabling advanced and highly demanding services along with a simultaneous drastic reduction of the OPEX.

  6. “Enhancing Satellite & Terrestrial Networks Integration through NFV/SDN technologies”, Dr Harilaos Koumaras, Research Associate in Media Networks Laboratory (MediaNet Lab), NCSR Demokritos, Institute of Informatics and Telecommunications
    14:30 – 15:00 / Session 4 / Room4


    • The combination of satellite and terrestrial components to form a single/integrated telecom network has been regarded for a long time as a promising approach to significantly improve the delivery of communications services. In this context, the satellite industry is clearly committed to revisit and revamp the role of satellite communications in the context of next generation 5G networks, following the paradigm of the terrestrial domain, where limitations such as the lack of automation, limited flexibility in scaling/upgrading networking equipment and services noted above for satellite communications are also present but gradually being confronted via a major technological transition sustained in the emerging concepts and technologies of network function virtualization (NFV) and software-defined networking (SDN). This presentation advocates for the introduction and exploitation of the NFV/SDN paradigms and technologies into the satellite networking domain, as central enablers towards improved and more flexible integration of satellite and terrestrial segments, network service innovation and business agility, and network resources management.

  1. “Enhancing the security of CIIPs in Europe – ENISA’s Approach”, Dimitra Liveri,  Network and Information Security Expert ,Secure Infrastructures and Services Unit – European Network of Information Security Agency
    15:30 – 15:50 / Session 5 / Room4


    • Critical Information Infrastructure Protection is one of the most important objectives of the national cyber security strategies in Europe of the 28. ENISA, always supporting the Member States, has been working closely with the community to issue recommendations and highlight good practices in protecting these critical assets. Focusing on areas like the Finance sector, eHealth, Transport and Energy, ENISA is also influencing the policy makers to understand the emerging CIIP landscape and is contributing to the Commission’s strategic initiatives. The diverse cyber security landscape and the different priorities each country sets are two elements to take into account when suggesting harmonised solutions with the goal to reach a common maturity level: this is the goal of ENISA for CIIP in Europe.

  2. “Risk Mitigation for Critical Infrastructures: Research Initiatives”, G. Stergiopoulos, P. Kotzanikolaou, M. Theoharidou, D. Gritzalis, INFOSEC Laboratory, Dept. of Informatics Athens University of Economics and Business (AUEB), Dept. of Informatics, University of Piraeus, Joint Research Center Institute for the Protection and the Security of the Citizen
    15:50 – 16:10 / Session 5 / Room4


    • Critical infrastructures are the backbone of a nation’s economy, security, and  health. It is those infrastructures that provide power and water to homes, support the  transportation and communication systems people rely on. It is obvious that critical  infrastructures, along with their services and systems must be protected against all types  of failures; both human-made and natural phenomena. To this end, we must be in a  position to pinpoint potential cascading effects amongst depended critical infrastructures  and analyze the impact and potential likelihood of their occurring. Thus, the aim of this  work is twofold:(i) We developed a critical infrastructure dependency analysis methodology which uses   dynamic time-based analysis models. The proposed methodology uses different failure  models and applies fuzzy logic to simulate realistic approximations of dynamic cascading  failures between infrastructures. We implemented the methodology in a tool called CIDA,  which is able to simulate the effects of dynamic, large-scale and major disasters.(ii) We explored how graph centrality metrics can be applied to design and to evaluate the  effectiveness of risk mitigation strategies by pinpointing Critical Infrastructures of high  dependency value amongst interconnected infrastructures. Our algorithm is able to  explore the relation between dependency risk paths using graph centrality characteristics  and proposed critical infrastructures in networks that are critical in the overall stability of  the infrastructure web.

  3. “Software Defined Security Mechanisms for Critical Infrastructure Management”, Dr Anastasios Zafeiropoulos, Senior R&D Architect, UBITECH
    16:10 – 16:30 / Session 5 / Room4


    • Following the continuous evolution and adoption of Software Defined Networking (SDN) and Network Function Virtualization (NFV) technologies and the design of a set of innovative services that take advantage of such technologies, there is clear the potential for adopting such techniques for realising novel software-defined security solutions. In a software-defined world, security need to be everywhere within a network. SDN security needs to be built into the architecture, as well as delivered as a service to protect the availability, integrity, and privacy of all connected resources and information. Combined with the evolution of SDN mechanisms, NFV technologies offer a new way to design, deploy and manage services by decoupling the network function, such as firewalling and intrusion detection, from proprietary hardware appliances, so they can run in software. In this talk, we are providing an overview of the potential provided by SDN and NFV technologies towards the design of novel software-defined security solutions and provide insights with regards to ways that they can be applied for Critical Infrastructure Management purposes.

  4. “ROPInjector: Using Return-Oriented Programming for Polymorphism and Antivirus Evasion”, Giorgos Poulios, Christoforos Ntantogian, Christos Xenakis, Systems Security Laboratory, Department of Digital Systems, University of Piraeus
    16:30 – 16:50 / Session 5 / Room4


    • The downside of current polymorphism techniques lies to the fact that they require a writeable code section, either marked as such in the corresponding Portable Executable (PE) section header or by changing permissions during runtime. Both approaches are identified by AV software as alarming characteristics and/or behavior, since they are rarely found in benign PEs unless they are packed. In this paper we propose the use of Return-Oriented Programming (ROP) as a new way to achieve polymorphism and evade AV software. To this end, we have developed a tool named ROPInjector which, given any piece of shellcode and any non-packed 32-bit Portable Executable (PE) file, it transforms the shellcode to its ROP equivalent and patches it into (i.e. infects) the PE file. After trying various combinations of evasion techniques, the results show that ROPInjector can evade nearly and completely all antivirus software employed in the online VirusTotal service. The main outcome of this research is the developed algorithms for: a) analysis and manipulation of assembly code on the x86 instruction set, and b) the automatic chaining of gadgets by ROPInjector to form safe, and functional ROP code that is equivalent to a given shellcode.

  5. “Promoting Critical Infrastructure Security and Resilience”, George Eftychidis and George Leventakis, Center for Security Studies – Kemea, Ministry of Interior and Administrative Reconstruction.
    17:00 – 17:20 / Session 6 / Room4


    • The European Commission has set out since 2006 the principles and instruments needed to strengthen Security of both European and national Critical Infrastructures in context of the Council Directive 2004/114/EC and the European Programme for Critical Infrastructure Protection (EPCIP). Several R&D initiatives contribute to implementing this initiative. The Center for Security Studies – KEMEA, being the National Contact Point (NCP) for implementing the respective Presidential Decree 39/2011 in Greece contributes to two different research projects of the EC. The first (ARGOS) is a FP7 project concerning the development of an ICT solution aiming to support the physical protection of critical buildings and installations from malevolent actions  while the second (EU-CIRCLE) is a Horizon 2020 project focusing to the development of a modelling framework, which can analyze the resilience of critical infrastructures against impacts related to climate change. This presentation refers to the objectives and expected results of ARGOS and   EU-CIRCLE projects.

  6. Port Security: Results  from the EU projects SUPPORT and AUGGMED”,  Y. Papagianopoulos,  Pireaus Port Authority
    17:20 – 17:40 / Session 6 / Room4


    • Lines of authority and responsibility in port security are complex, even conflicting in some cases, and different in practically every European port.  Present security systems depend also, to a great extent, on a vast array of legacy systems which would be uneconomic to replace in their entirety. The challenge for SUPPORT, and its ultimate aim, is to create innovative, versatile, configurable and highly automated port security solutions that can thrive in such complex environments and bring about a new generation of port security practices.  To be able to achieve that, SUPPORT also aims at converting legacy systems into services that can be seamlessly combined with new innovative solutions.In addition, common approaches and interdependencies with the AUGGMED are also explored.

  7. “Medusa: A risk assessment tool for ports’ supply chain services”, Dr. S. Papastergiou, Assoc. Professor N. Polemi,  Dept. of Informatics, University of Piraeus
    17:40 – 18:00 / Session 6 / Room4


    • The main objective of MEDUSA is to contribute to the effective protection of the maritime supply chain that arises from the ICT and physical interconnections and interdependencies of a set of maritime entities (e.g. port authorities, ministries, maritime companies, ship industry, customs agencies, maritime/ insurance companies other transport CIIs (e.g. airports) and other CIIs (e.g. transport networks, energy networks, telecommunication networks)). Serving this scope, the MEDUSA project has developed an innovative, open, collaborative, integrated, comprehensive and personalized Risk Management system in order to continuously monitor the efficient identification, assessment and treatment of cyber and physical risks and threats associated with three specific multi-sector cross-border supply chain scenarios (the Vehicles Transport, the Container Management and the LNG Transport). The presentation will provide a brief overview of the main capabilities and the supported functionality of the proposed MEDUSA Risk Management system.
