In this paper, we present already existing academic experience and literature about Cybersecurity training related topics, through attack and defense scenarios in a specially configured environment, which for the purposes of defense includes a Security Operations Center and for the purposes of the attack includes specially configured information systems which are intentionally vulnerable. Our results indicate that while there is existing literature available regarding the creation of functional SOC for educational purposes, it is not combined or used with applied attack and defense scenarios. There are also no instructions for practical use of the available information for educational purposes. We propose a theoretical structure and topology of an environment that can be used for applied training in Cybersecurity through attack scenarios using intentionally vulnerable information systems as targets and defense scenarios using a SOC to detect and respond to those attacks.","PeriodicalId":164036,"journal":{"name":"Proceedings of the 26th Pan-Hellenic Conference on Informatics","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130044495","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Citizen (or customer) satisfaction is determined and influenced by a variety of factors, such as the municipality's environment, operations, document requirements and customer service representative behavior, among others. The main purpose of this study is to create a tool for co-creation and co-design in public service provision by using Natural Language Processing techniques to analyze all the available reviews on Greek municipalities, in order to determine the current status of service quality and customer satisfaction, while also suggesting future improvements that can be derived based on the study results. Five major topics that municipalities must focus on in order to provide services to citizens emerged: \"services and processes\", \"response time and location of municipality\", \"employees\", \"communication channels\", and \"employees’ behavior\". These five identified topics can be utilized to improve the service provision behind each of them, towards the end-users. In this manner, the citizens can actively participate towards the improvement of processes based on their needs, requirements and expectations.","PeriodicalId":164036,"journal":{"name":"Proceedings of the 26th Pan-Hellenic Conference on Informatics","volume":"30 17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128883219","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, straightforward yet interactive and easy-to-understand tools let users’ complex demands be satisfied within minutes. The objective of this work is to give an optimized graphical user interface for the Apache Spark MLlib library to apply machine learning algorithms quickly, conveniently, and effectively. We introduce SparkReact, a responsive graphical user interface that allows users to apply clustering, classification, and regression techniques within just a few mouse clicks by implementing and evaluating a certain algorithm and pre-building the code ready for import to Spark. To evaluate the usefulness of our tool we performed crowdsourcing to two categories, computer experts and ordinary users. The results indicate that both populations were satisfied with the tool at a surprising 98 percent. As per the time required to construct and evaluate a machine learning model, it took approximately 4 minutes using SparkReact while with ordinary methods it took almost 4 times longer. Ultimately, future extensions will seek to provide more algorithmic choices.","PeriodicalId":164036,"journal":{"name":"Proceedings of the 26th Pan-Hellenic Conference on Informatics","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125782814","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
