Pigmans, Max (author)Most of the adversarial attacks suitable for attacking decision tree ensembles work by doing multiple local searches from randomly selected starting points, around the to be attacked victim. In this thesis we investigate the impact of these starting points on the performance of the attack, and find that the starting points significantly impact...master thesis 2024

Gnanavarothayan, Kabilan (author)The use of Internet of Things (IoT) devices has experienced an increase since its inception and is expected to continue to do so. However, this growth has also attracted individuals with malicious intentions. Botnet attacks on IoT devices have become more potent each year, exploiting new vulnerabilities and attacking more devices. Therefore, it...master thesis 2023

ZHANG, JIAXUAN (author)Cyber-physical systems are vulnerable to malicious attacks, which can lead to severe consequences. Active detection methods have emerged as a promising approach for identifying such attacks. However, existing active detection methods are susceptible to malicious parameter identification attacks, where attackers exploit eavesdropped data to...master thesis 2023

Kruijsse, Hendrik Jan (author)Nowadays, the society strongly depends on computer networks and systems as a means of reliable communication and data storage. In order to maintain absolute security of the networks and thus the society, one would need to separate everything, but this is not feasible. Consequently, sharing of resources is inevitable. There are security products...master thesis 2023

Murillo, Andrés (author), Taormina, R. (author), Tippenhauer, Nils Ole (author), Galelli, Stefano (author)A fundamental problem in the realm of cyber-physical security of smart water networks is attack detection, a key step towards designing adequate countermeasures. This task is typically carried out by algorithms that analyze time series of process data. However, the nature of the data available to develop these algorithms limits their...journal article 2023

Presekal, A. (author), Stefanov, Alexandru (author), Subramaniam Rajkumar, Vetrivel (author), Palensky, P. (author)The cyber attacks in Ukraine in 2015 and 2016 demonstrated the vulnerability of electrical power grids to cyber threats. They highlighted the significance of Operational Technology (OT) communication-based anomaly detection. Many anomaly detection methods are based on real-time traffic monitoring, i.e., Intrusion Detection Systems (IDS) that may...conference paper 2023

Akkaoui, R. (author), Stefanov, Alexandru (author), Palensky, P. (author), Epema, D.H.J. (author)The solar industry in residential areas has been witnessing an astonishing growth worldwide. At the heart of this transformation, affecting the edge of the electricity grid, reside smart inverters (SIs). These IoT-enabled devices aim to introduce a certain degree of intelligence to conventional inverters by integrating various grid support...journal article 2023

Presekal, A. (author), Stefanov, Alexandru (author), Subramaniam Rajkumar, Vetrivel (author), Palensky, P. (author)Electrical power grids are vulnerable to cyber attacks, as seen in Ukraine in 2015 and 2016. However, existing attack detection methods are limited. Most of them are based on power system measurement anomalies that occur when an attack is successfully executed at the later stages of the cyber kill chain. In contrast, the attacks on the Ukrainian...journal article 2023

Al-Kaswan, Ali (author)Reverse engineering binaries is required to understand and analyse programs for which the source code is unavailable. Decompilers can transform the largely unreadable binaries into a more readable source code-like representation. However, many aspects of source code, such as variable names and comments, are lost during the compilation and...master thesis 2022

Thiessen, Sven (author)The uprise of the Internet of Things (IoT) has been a hot topic for several years. While many see these devices and think they bring ease to their lives, it is far from reality. Researchers found many privacy and security problems within these devices in the last years. The popularity of these devices causes many users to bring a device into...master thesis 2022

Steenbrink, Tim (author)Recent advances in the field of ‘Zero Trust’ security strategies have revealed that there is still much novelty regarding the concept of Zero Trust architecture (ZTA). Zero Trust has recently gained attention as the traditional approach, based on network perimeter security, is being outplayed by sophisticated cyber attacks. This research...master thesis 2022

Maquelin, Suzanne (author)Interpreted applications are often vulnerable to remote code execution attacks. To protect interpreted applications, we should reduce the tools available to the attackers. In this thesis, we investigate the possibilities for the automation of policy generation for interpreted applications in terms of system call arguments. These policies are...master thesis 2022

de Los Santos Subirats, Alex (author)Software-Defined Networks (SDNs) are a promising new network design paradigm that allows for better control of the network. But as with any new software implementation, there are new security concerns that arise. In the past there have been various papers covering specific side-channel attacks on SDNs; most of them consist of either using time...bachelor thesis 2022

Jeong, Yoon Hwan (author)In order to combat increasing spam calls, many applications are developed and downloaded to block those calls. Some studies about performance of the applications were previously conducted, however, the actual processes the applications go through to intercept and block the spam calls are not well studied. This research presents a method to...bachelor thesis 2022

Mulder, Tijmen (author)From 2019 into 2021, phishing incidents tripled, while phishing was found to be the largest used cyberattack vector. One commonly used type of phishing is a credential phishing attack over email. This is an act where an attacker tries to steal credential information from a target via a phishing website. This phishing website is delivered to the...master thesis 2022
