Item A Survey on honeypots, honeynets and their applications on smart grid(Institute of Electrical and Electronics Engineers Inc., 2019-06) Dalamagkas, Christos; Sarigiannidis, Panagiotis; Ioannidis, Dimosthenis; Iturbe, Eider; Nikolis, Odysseas; Ramos, Francisco; Rios, Erkuden; Sarigiannidis, Antonios; Tzovaras, Dimitrios; Jacquenet, Christian; De Turck, Filip; Chemouil, Prosper; Esposito, Flavio; Festor, Olivier; Cerroni, Walter; Secci, Stefano; CIBERSEC&DLTPower grid is a major part of modern Critical Infrastructure (CIN). The rapid evolution of Information and Communication Technologies (ICT) enables traditional power grids to encompass advanced technologies that allow them to monitor their state, increase their reliability, save costs and provide ICT services to end customers, thus converting them into smart grids. However, smart grid is exposed to several security threats, as hackers might try to exploit vulnerabilities of the industrial infrastructure and cause disruption to national electricity system with severe consequences to citizens and commerce. This paper investigates and compares honey-x technologies that could be applied to smart grid in order to distract intruders, obtain attack strategies, protect the real infrastructure and form forensic evidence to be used in court.Item Towards an anonymous incident communication channel for electric smart grids(Association for Computing Machinery, 2018-11-29) Triantafyllou, Anna; Sarigiannidis, Panagiotis; Sarigiannidis, Antonios; Rios, Erkuden; Iturbe, Eider; Mamalis, Basilis; Karanikolas, Nikitas N.; CIBERSEC&DLTThe Electric Smart Grid (ESG) is an intelligent critical infrastructure aiming to create an automated and distributed advanced energy delivery network, while preserving information privacy. This study proposes the implementation of an Anonymous Incident Communication Channel (AICC) amongst smart grids across Europe to improve situational awareness and enhance security of the new electric intelligent infrastructures. All participating organizations will have the ability to broadcast sensitive information, stored anonymously in a repository, without exposing the reputation of the organisation. This work focuses on the requirements of establishment, the possible obstacles and proposed data protection techniques to be applied in the AICC. Furthermore, a discussion is conducted regarding the documentation of cyber-incidents. Last but not least, the benefits and the potential risks of this AICC concept are also provided.
