Item Dynamic Risk Assessment and Certification in the Power Grid: A Collaborative Approach(Institute of Electrical and Electronics Engineers Inc., 2022) Liatifis, Athanasios; Alcazar, Pedro Ruzafa; Grammatikis, Panagiotis Radoglou; Papamartzivanos, Dimitris; Menesidou, Sofianna; Krousarlis, Thomas; Alberto, Molinuevo Martin; Angulo, Inaki; Sarigiannidis, Antonios; Lagkas, Thomas; Argyriou, Vasileios; Skarmeta, Antonio; Sarigiannidis, Panagiotis; Clemm, Alexander; Maier, Guido; Machuca, Carmen Mas; Ramakrishnan, K.K.; Risso, Fulvio; Chemouil, Prosper; Limam, Noura; SWT; DIGITAL ENERGYThe digitisation of the typical electrical grid introduces valuable services, such as pervasive control, remote monitoring and self-healing. However, despite the benefits, cybersecurity and privacy issues can result in devastating effects or even fatal accidents, given the interdependence between the energy sector and other critical infrastructures. Large-scale cyber attacks, such as Indostroyer and DragonFly have already demonstrated the weaknesses of the current electrical grid with disastrous consequences. Based on the aforementioned remarks, both academia and industry have already designed various cybersecurity standards, such as IEC 62351. However, dynamic risk assessment and certification remain crucial aspects, given the sensitive nature of the electrical grid. On the one hand, dynamic risk assessment intends to re-compute the risk value of the affected assets and their relationships in a dynamic manner based on the relevant security events and alarms. On the other hand, based on the certification process, new approach for the dynamic management of the security need to be defined in order to provide adaptive reaction to new threats. This paper presents a combined approach, showing how both aspects can be applied in a collaborative manner in the smart electrical grid.Item ELECTRON: An Architectural Framework for Securing the Smart Electrical Grid with Federated Detection, Dynamic Risk Assessment and Self-Healing(Association for Computing Machinery, 2023-08-29) Radoglou-Grammatikis, Panagiotis; Liatifis, Athanasios; Dalamagkas, Christos; Lekidis, Alexios; Voulgaridis, Konstantinos; Lagkas, Thomas; Fotos, Nikolaos; Menesidou, Sofia Anna; Krousarlis, Thomas; Alcazar, Pedro Ruzafa; Martinez, Juan Francisco; Skarmeta Gomez, Antonio Fernando; Martín, Alberto Molinuevo; Angulo, Inaki; Nieto, Jesus Villalobos; Koshutanski, Hristo; Rodriguez, Rodrigo Diaz; Siniosoglou, Ilias; Mavropoulos, Orestis; Kyranou, Konstantinos; Saoulidis, Theocharis; Adir, Allon; Masalha, Ramy; Jimenez, Pablo Gallegos; Bellini, Emanuele; Kolokotronis, Nicholas; Shiaeles, Stavros; Franquelo, Jose Garcia; Lalas, George; Zalonis, Andreas; Voulgaridis, Antonis; Bintoudi, Angelina; Votis, Konstantinos; Pampliega, David; Sarigiannidis, Panagiotis; SWT; DIGITAL ENERGYThe electrical grid has significantly evolved over the years, thus creating a smart paradigm, which is well known as the smart electrical grid. However, this evolution creates critical cybersecurity risks due to the vulnerable nature of the industrial systems and the involvement of new technologies. Therefore, in this paper, the ELECTRON architecture is presented as an integrated platform to detect, mitigate and prevent potential cyberthreats timely. ELECTRON combines both cybersecurity and energy defence mechanisms in a collaborative way. The key aspects of ELECTRON are (a) dynamic risk assessment, (b) asset certification, (c) federated intrusion detection and correlation, (d) Software Defined Networking (SDN) mitigation, (e) proactive islanding and (f) cybersecurity training and certification.
