Infrastructural Challenges and Good Practices in a Security Operation Center

Authors: Dimitri Alexandre da Silva, José Luís Costa, and João Rafael Almeida

Published in: OASIcs, Volume 120, 13th Symposium on Languages, Applications and Technologies (SLATE 2024)

Abstract
Organizations are facing some challenges in cybersecurity, due to the increasing of cyber threats, vulnerabilities, insufficient cybersecurity frameworks, and scarcity of proficient cybersecurity experts. The criticality of mitigating these challenges is underscored by the European Union’s Network and Information Systems (NIS) Directive. This directive is instrumental in fostering a uniformly high level of cybersecurity throughout the EU, mandating that Member States implement robust national cybersecurity strategies and collaborate effectively in responding to cyber incidents. A possible solution is the implementation of a Security Operations Center (SOC). However, SOCs are not a one-size-fits-all solution and each organization has specific needs depending on their business domain. This task can be complex, and it can be simplified when organizations can identify in the initial stages the infrastructural challenges that may emerge when implementing a SOC. In this paper, we analyzed the main considerations that should be considered when using current frameworks reviewed in the literature. We identified the core operating models that are currently in use and being deployed, and which are the best practices when designing a SOC’s infrastructure.

A Study of Security Issues of Eduroam Networks in Portugal

Authors: Luís Miguel Batista, Hélder Gomes, and João Rafael Almeida

Published in: OASIcs, Volume 120, 13th Symposium on Languages, Applications and Technologies (SLATE 2024)

Abstract
Enterprise Wi-Fi networks provide seamless connectivity for businesses and public entities. In educational settings, these networks are essential for delivering services to students. Eduroam is one of the most widely recognized university Wi-Fi enterprise networks. It uses 802.1x protocols and TLS tunnels to establish mutual authentication. Eduroam caters to a diverse population of students and faculty worldwide, managing a vast number of unregulated devices, some of which, require manual configuration to operate in a secure setting. This study aims to evaluate the security robustness of the 802.1x protocol, particularly within the Eduroam framework. A comprehensive study was conducted to examine compliance with institutional instructions for network configuration guidance. The results from 91 Portuguese institutions using Eduroam revealed that many lacked knowledge of Wi-Fi security. This lack of awareness is then passed on to users, resulting in vulnerable connections.

Question Answering For Toxicological Information Extraction

Authors: Bruno Carlos Luís Ferreira, Hugo Gonçalo Oliveira, Hugo Amaro, Ângela Laranjeiro, and Catarina Silva

Published in: OASIcs, Volume 104, 11th Symposium on Languages, Applications and Technologies (SLATE 2022)

Abstract
Working with large amounts of text data has become hectic and time-consuming. In order to reduce human effort, costs, and make the process more efficient, companies and organizations resort to intelligent algorithms to automate and assist the manual work. This problem is also present in the field of toxicological analysis of chemical substances, where information needs to be searched from multiple documents. That said, we propose an approach that relies on Question Answering for acquiring information from unstructured data, in our case, English PDF documents containing information about physicochemical and toxicological properties of chemical substances. Experimental results confirm that our approach achieves promising results which can be applicable in the business scenario, especially if further revised by humans.

Classification of Public Administration Complaints

Authors: Francisco Caldeira, Luís Nunes, and Ricardo Ribeiro

Published in: OASIcs, Volume 104, 11th Symposium on Languages, Applications and Technologies (SLATE 2022)

Abstract
Complaint management is a problem faced by many organizations that is both vital to customer image and highly dependent on human resources. This work attempts to tackle a part of the problem, by classifying summaries of complaints using machine learning models in order to better redirect these to the appropriate responders. The main challenges of this task is that training datasets are often small and highly imbalanced. This can can have a big impact on the performance of classification models. The dataset analyzed in this work suffers from both of these problems, being relatively small and having labels in different proportions. In this work, two different techniques are analyzed: combining classes together to increase the number of elements of the new class; and, providing new artificial examples for some classes via translation into other languages. The classification models explored were the following: k-NN, SVM, Naïve Bayes, boosting, and Deep Learning approaches, including transformers. The paper concludes that although, as expected, the classes with little representation are hard to classify, the techniques explored helped to boost the performance, especially in the classes with a low number of elements. SVM and BERT-based models outperformed their peers.

Reasoning with Portuguese Word Embeddings

Authors: Luís Filipe Cunha, J. João Almeida, and Alberto Simões

Published in: OASIcs, Volume 104, 11th Symposium on Languages, Applications and Technologies (SLATE 2022)

Abstract
Representing words with semantic distributions to create ML models is a widely used technique to perform Natural Language processing tasks. In this paper, we trained word embedding models with different types of Portuguese corpora, analyzing the influence of the models' parameterization, the corpora size, and domain. Then we validated each model with the classical evaluation methods available: four words analogies and measurement of the similarity of pairs of words. In addition to these methods, we proposed new alternative techniques to validate word embedding models, presenting new resources for this purpose. Finally, we discussed the obtained results and argued about some limitations of the word embedding models' evaluation methods.

Digital Collection Creator, Visualizer and Explorer

Authors: Luís F. Martins, Cristiana Araújo, and Pedro Rangel Henriques

Published in: OASIcs, Volume 74, 8th Symposium on Languages, Applications and Technologies (SLATE 2019)

Abstract
In this paper we introduce and discuss a recent project, called CortaColaEspia, aimed at extending with some extra relevant features the 'Ontology-based Collection Processor' developed previously in the context of a Compilers course. The basic processor, based on the OntoDL tool, was able to read the ontological description of a small collection of objects (cards, pencils, toys, etc.) and produce automatically a web-based exhibition space to display the objects, providing a conceptual navigation through them. The extension under discussion is intended to create a new DSL to describe the details of the exhibition room organization (what concepts and relations to show; where and how to show them; etc.). A second objective consists of a new module to merge two collections, or to enrich a collection with extra information about the collected objects. The last requirement is the incorporation of a natural language processor to analyze the objects' captions or short inscriptions in order to extract information that can create knowledge about a specific domain, a society or an epoch.

I will provide a historical perspective on wait-free simulations of multi-bit shared registers using single-bit shared registers, starting with classical results from the last century and ending with an overview of the recent resurgence of interest in the topic. Particular emphasis will be placed on the space and step complexities of such simulations.

Distributed Systems and Databases of the Globe Unite! The Cloud, the Edge and Blockchains (Keynote)

Abstract
Significant paradigm shifts are occurring in Access patterns are widely dispersed and large scale analysis requires real-time responses. Many of the fundamental challenges have been studied and explored by both the distributed systems and the database communities for decades. However, the current changing and scalable setting often requires a rethinking of basic assumptions and premises. The rise of the cloud computing paradigm with its global reach has resulted in novel approaches to integrate traditional concepts in novel guises to solve fault-tolerance and scalability challenges. This is especially the case when users require real-time global access. Exploiting edge cloud resources becomes critical for improved performance, which requires a reevaluation of many paradigms, even for a traditional problem like caching. The need for transparency and accessibility has led to innovative ways for managing large scale replicated logs and ledgers, giving rise to blockchains and their many applications. In this talk we will be explore some of these new trends while emphasizing the novel challenges they raise from both distributed systems as well as database points of view. We will propose a unifying framework for traditional consensus and commitment protocols, and discuss novel protocols that exploit edge computing resources to enhance performance. We will highlight the advantages and discuss the limitations of blockchains. Our overall goal is to explore approaches that unite and exploit many of the significant efforts made in distributed systems and databases to address the novel and pressing needs of today's global computing infrastructure.
