Actively detecting multiscale flooding attacks & attack volumes in resource-con...
Zahid, Farzana; Kuo, Matthew M.Y.; Sinha, Roopak; Funchal, Gustavo Silva; Pedrosa, Tiago; Leitão, PauloThe significant growth in modern communication technologies has led to an increase in zero-day vulnerabilities that degrade the performance of cyber-physical systems (ICPS). Distributed denial of service (DDoS) attacks are one such threat that overwhelms a target with floods of packets, posing a severe risk to the normal operations of the ICPS. Current solutions to detect DDoS attacks are unsuitable for resourc...
Parameterization and performance analysis of a scalable, near real-time packet ...
Oliveira, Rafael Cardoso de; Pedrosa, Tiago; Rufino, José; Lopes, Rui PedroThe rapid evolution of technology has fostered an exponential rise in the number of individuals and devices interconnected via the Internet. This interconnectedness has prompted companies to expand their computing and communication infrastructures significantly to accommodate the escalating demands. However, this proliferation of connectivity has also opened new avenues for cyber threats, emphasizing the critic...
Edge Multi-agent Intrusion Detection System Architecture for IoT Devices with C...
Funchal, Gustavo Silva; Pedrosa, Tiago; Prieta Pintado, Fernando De la; Leitão, PauloThe Industry 4.0 has brought significant changes in production processes and business models worldwide. Advanced technologies, e.g., Collaborative Robotics, Artificial Intelligence, Cloud Computing, and Internet of Things (IoT) are playing a crucial role in improving efficiency and productivity. However, the adoption of these technologies, particularly IoT, introduces security vulnerabilities and potential atta...
Query log analysis for SQL injection detection
Rocha, Alexandra; Alves, Rui; Pedrosa, TiagoNowadays, more and more services are dependent on the use of resources hosted on the web. The realization of operations such as access to the account bank, credit card operations, among other operations, is something increasingly common in current times, demonstrating not only human dependence on the internet connection, as well as the need to adapt the web resources to the daily life of society. As a result of...
An intrusion detection system dataset for a multi-agent cyber-physical conveyor...
Funchal, Gustavo Silva; Zahid, Farzana; Melo, Victoria; Kuo, Matthew M.Y.; Pedrosa, Tiago; Sinha, Roopak; Prieta Pintado, Fernando De la; Leitão, PauloIndustry 4.0 is built upon the foundation of connecting devices and systems via Internet of Things (IoT) technologies, with Cyber-Physical Systems (CPS) serving as the backbone infrastructure. Although this approach brings numerous benefits like improved performance, responsiveness and reconfigurability, it also introduces security concerns, making devices and systems vulnerable to cyber attacks. There is a nee...
Secure data exchange in Industrial Internet of Things
Sukiasyan, Anna; Badikyan, Hasmik; Pedrosa, Tiago; Leitão, PauloThe use of the Industrial Internet of Things (IoT) is widespread, working as an enabler to implement large, scalable, reliable, and secure industrial environments. Although existing deployments do not meet security standards and have limited resources for each component which leads to several security breaches, such as trust between components, partner factories, or remote-control. These security failures can l...
Learning cybersecurity in iot-based applications through a capture the flag com...
Junior, Alexandre Oliveira; Funchal, Gustavo Silva; Queiroz, Jonas; Loureiro, Jorge; Pedrosa, Tiago; Parra, Javier; Leitão, PauloThe Internet of Things (IoT) is one of the main foundations of Industry 4.0, providing widespread connectivity of systems and devices, which promotes significant benefits, such as improved performance, responsiveness, and reconfigurability. However, it also brings some security problems, which make these devices and systems vulnerable to cyberattacks, consequently demanding efficient learning and training initi...
System architecture for home muscle rehabilitation treatment
Franco, Tiago; Henriques, Pedro Rangel; Alves, Paulo; Pereira, Maria João; Pedrosa, Tiago; Silva, F.; Leitão, Paulo; Oliveira, L.The constant loss of functional capacity due to aging is a serious problem that can severely worsen the quality of life. Among the possible treatments, muscles electrostimulation can be a viable option because it is cheap and easy to access. With the evolution of wearable devices and the Internet of Things, this paper proposes a system architecture that enables an electrostimulation treatment to be performed at...
A scalable, real-time packet capturing solution
Oliveira, Rafael Cardoso de; Almeida, João P.; Praça, Isabel; Lopes, Rui Pedro; Pedrosa, TiagoThe evolution of technology and the increasing connectivity between devices lead to an increased risk of cyberattacks. Good protection systems, such as Intrusion Detection System (IDS) and Intrusion Prevention System (IPS), are essential in trying to prevent, detect and counter most of the attacks. However, the increasing creativity and type of attacks raise the need for more resources and processing power for ...
Implementation of big data analytics tool in a higher education institution
Franco, Tiago; Alves, Paulo; Pedrosa, Tiago; Pereira, Maria João; Canão, JoséIn search of intelligent solutions that could help improve teaching in higher education, we discovered a set of analyzes that had already been discussed and just needed to be implemented. We believe that this reality can be found in several educational institutions, with paper or mini-projects that deal with educational data and can have positive impacts on teaching. Because of this, we designed an architecture...
