Item type:Publication, Observable and Reproducible Sandbox Environment for Cybersecurity Research(IEEE, 2026-07); ; The availability of controlled sandbox environments from which relevant network traces and system logs can be obtained is a prerequisite for studying network attacks. Such data is also essential for the development of novel security tools as well as for evaluating the effectiveness of various incident response strategies. A persistent challenge faced by security researchers is how to set up these environments in a consistent manner, guaranteeing the integrity of the underlying infrastructure while still providing meaningful data. In this paper we present the design of a secure, reproducible, and observable sandbox in which purposefully vulnerable applications are deployed and exploited. Every interaction is monitored in real time using strategically placed network probes, performance monitoring agents, and log shippers. The use of modern configuration management tools eliminates configuration drift and entropy, guaranteeing reproducibility of the deployed scenarios. We describe practical approaches for implementing the sandbox, detailing the tools and methods required for real-world deployment. Using a recent sandbox instantiation as an example, we demonstrate how the acquired network data can be used to identify attack patterns, analyze defense strategies, and assess overall incident response effectiveness. The obtained dataset is open-sourced and can be reused to support further research. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, MetriKG: Profiling Static and Evolving Knowledge Graphs(ACM, 2026-05-28) ;Günes, Hasan H.; Hose, KatjaKnowledge graphs (KGs) are a foundational technology for representing and integrating information across heterogeneous domains. As some KGs evolve, understanding how their structural and semantic properties change over time is crucial for ensuring quality, consistency, and interpretability. Existing methods for KG evaluation often focus on static graphs or analyze evolution solely at the data level, leaving schema-level dynamics underexplored. To address this gap, we introduce MetriKG, a web-based application that computes a comprehensive set of metrics for both static and evolving KGs. MetriKG enables users to evaluate KGs provided as RDF files or through SPARQL endpoints, allowing for multi-dimensional analysis of aspects such as cohesion, connectivity, and inheritance depth. By supporting metric computation at both data and schema levels, MetriKG allows for systematic profiling, classification, and temporal monitoring of KGs. MetriKG is open-source and publicly available. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Privacy preserving synchronization of directed dynamical networks with periodic data-sampling(Elsevier BV, 2025-01) ;Jia, Qiang ;Yao, XinyiData privacy has become a key issue in networked systems, but few effort was devoted to privacy preservation in synchronization of nonlinear dynamical networks when data sampling is involved. This work focuses on the privacy preserving synchronization in a type of nonlinear dynamical network with sampled data. In order to preserve their private initial states, the nodes conceal the sampled data via certain deterministic perturbation, and exchange the masked data with their neighbors via the communication network. A novel privacy-preserving protocols with sampled data is developed, which differs from existing designs with continuous data, and a commonly used restriction on the nodes’ neighbor sets is unnecessary herein. By establishing a new Halanay-type inequality with decaying perturbation, some sufficient criteria are derived to guarantee synchronization without disclosing the nodes’ privacy, revealing how the decaying rate of the masking functions, the topology and the sampling period influence synchronization. Furthermore, in order to reduce the control update, the analogue of the above design with event-trigger is also given, leading to another useful condition for privacy preserving synchronization. Some numerical examples are finally given to validate the theoretical results and demonstrate the effectiveness of the proposed designs. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, ANTI-VIRUS TOOLS ANALYSIS USING DEEP WEB MALWARES(AIRCC Publication Corporation, 2018-12-22); ;Šćepanović, Sanja; Knowledge about the strength of the anti-virus engines (i.e. tools) to detect malware files on the Deep web is important for people and companies to devise proper security polices and to choose the proper tool in order to be more secure. In this study, using malware file set crawled from the Deep web we detect similarities and possible groupings between plethora of anti-virus tools (AVTs) that exist on the market. Moreover, using graph theory, data science and visualization we find which of the existing AVTs has greater advantage in detecting malware over the other AVTs, in a sense that the AVT detects many unique. Finally, we propose a solution, for the given malware set, what is the best strategy for a company to defend against malwares if it uses a multi-scanning approach. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Interplay Between Spreading and Random Walk Processes in Multiplex Networks(Institute of Electrical and Electronics Engineers (IEEE), 2017-10); ; ;Scepanovic, SanjaReal networks in our surrounding are usually complex and composite by nature and they consist of many interwoven layers. The commutation of agents (nodes) across layers in these composite multiplex networks heavily influences the underlying dynamical processes, such as information, idea and disease spreading, synchronization, consensus, etc. In order to understand how the agents' dynamics and the compositeness of multiplex networks influence the spreading dynamics, we develop a susceptible-infected-susceptible-based model on the top of these networks, which is integrated with the transition of agents across layers. Moreover, we analytically obtain a critical infection rate for which an epidemic dies out in a multiplex network, and latter show that this rate can be higher compared with the isolated networks. Finally, using numerical simulations we confirm the epidemic threshold and we show some interesting insights into the epidemic onset and the spreading dynamics in several real and generic multiplex networks. - Some of the metrics are blocked by yourconsent settings
