Industrial cyber-physical systems protection: A methodological review
No full textUbiquitous utilization of Information and Communication Technologies in modern manufacturing plants has transformed them into Cyber-Physical Systems (CPSs), making them susceptible to cyber-attacks, which can have huge economic and social impact. In this paper, we focus on the security issues that may affect the Industrial Control System (ICS) supervising an industrial establishment. The purpose of this work is to provide readers with an up-to-date view of the methodologies that current literature suggests as the most appropriate to defend an ICS against cyber-attacks. We firstly provide a classification of existing attacks according to the methodology used by the attacker. Subsequently, we propose a classification of defensive countermeasures in Model and Artificial Intelligence-based approaches by analyzing most recent research contributions. Furthermore, we describe the most used datasets in literature that are available to researchers and practitioners. We conclude the paper by discussing today's open issues, which need to be addressed to cope with the increasing complexity of ICS security

Suggesting cultural heritage points of interest through a specialized chatbot
No full textResearchers and companies are making great efforts to create new ways of interaction with a increasing number and types of electronic devices, with particular attention to the conversational interface, whether spoken or written. The cultural heritage domain can bring many benefits from the great effort in this field, as a smart conversational system can provide both room/hotel/apartment information and information related to the area, natural or cultural points of interest, tourist routes, social events, history etc. The paper’s main goal is to present a quick and effective service to the tourists visiting a city for the first time. Learning the cultural preferences of the users can enhance customer satisfaction, since a smart system can propose them customised tours in order to reach point of interests according to the expressed preferences. The interaction with the user is simplified by a conversational interface (chatbot). © Springer Nature Switzerland AG 2021
Software Defined Wide Area Networks: Current Challenges and Future Perspectives
No full textSoftware Defined Wide Area Network (SD-WAN) is rapidly becoming an attractive solution for enterprise networks as it offers several benefits such as cost efficiency, increased bandwidth, and improved application performance. However, SDWAN also brings new challenges that must be addressed for effective deployment (i.e. openness, interoperability, network automation, monitoring, QoS guarantees, scalability and security). In this paper, we highlight the criticalities of this technology and analyze the solutions proposed by the state of the art. We then present a scalable framework based on distributed Reinforcement Learning agents for guaranteeing availability and QoS to business applications. We believe that our work provides valuable insights into the opportunities and challenges of SD-WAN technology and offers new perspectives for future research in this area
