Item ANALISIS DE RIESGOS DE CIBERSEGURIDAD EN ARQUITECTURA DE VEHICULOS AUTOMATIZADOS(2018) González, Leonardo; Vaca, Myriam; Lattarulo, Ray A.; Calvo, Isidro; Perez, Joshue; Ruiz, AlejandraLos vehiculos conectados y automatizados han sido recientemente concebidos como entes ci- berf sicos, estrechamente relacionados con la red del Internet de las cosas (IoT). Este hecho supone un incremento en la super cie de ataque del veh culo, que junto a la creciente tendencia hacia veh culos automatizados, hacen que estos riesgos de ciberseguridad puedan tener conse- cuencias catastr o cas en seguridad vial. En el presente trabajo se expone un an alisis de riesgos de ciberseguridad en el marco de una arquitectura de veh culos automatizados. Este an alisis previo se realiza en el contexto de dos escenarios de estudio en maniobras cooperativas. Inicialmente se presenta un estado del arte de la ciberseguridad en automoci on, as como tambi en su repercusi on en entornos automatizados, haciendo especialenfasis en las comunicaciones entre veh culos y con infraestructura. Adem as, se analizan dos maniobras cooperativas, y se ilustran una serie de posibles ataques en la plataforma.Item Substation-Aware. An intrusion detection system for the IEC 61850 protocol.(Association for Computing Machinery, 2022-08-23) Lopez, Jose Antonio; Angulo, Iñaki; Martinez, Saturnino; POWER SYSTEMS; DIGITAL ENERGY; Tecnalia Research & InnovationThe number of cyberattacks against the Smart Grid has increased in the last years. Considered as a critical infrastructure, power system operators must improve the cybersecurity countermeasures of their installations. Intrusion Detection Systems (IDS) appears as a promising solution to detect hidden activity of the hackers before launching the attack. Most detection tools are generalist, designed to find predefined patterns such as frequency of messages, well-known malware packets, source and destination of the messages or the content of each packet itself. These tools also allow plugging modules for different protocols, offering a better understanding of the analysed data, such as the protocol action (read, write, reset...) or data model/schema understanding. However, the semantics of the data transmitted cannot be inferred. The Substation-Aware (SBT-Aware) tool adds the latest feature for primary and secondary substations, taking into account not only the protocols defined in the IEC 61850 standard, but the substation topology as well. In this paper we present the SBT-Aware, an IDS that has been developed and tested in the course of the H2020 SDN-microSENSE project.
