The Faculty of Computer Science and Engineering (FCSE) within UKIM is the largest and most prestigious faculty in the field of computer science and technologies in Macedonia, and among the largest faculties in that field in the region. The FCSE teaching staff consists of 50 professors and 30 associates. These include many “best in field” personnel, such as the most referenced scientists in Macedonia and the most influential professors in the ICT industry in the Republic of Macedonia.

    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.

    MetriKG: Profiling Static and Evolving Knowledge Graphs

    Knowledge 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.

    RDFGraphGen: An RDF Graph Generator Based on SHACL Shapes

    Developing and testing modern RDF-based applications often requires access to RDF datasets with certain characteristics. Unfortunately, it is very difficult to publicly find domain-specific knowledge graphs that conform to a particular set of characteristics. Hence, in this paper we propose RDFGraphGen, an open-source RDF graph generator that uses characteristics provided in the form of SHACL (Shapes Constraint Language) shapes to generate synthetic RDF graphs. RDFGraphGen is domain-agnostic, with configurable graph structure, value constraints, and distributions. It also comes with a number of predefined values for popular schema.org classes and properties, for more realistic graphs. Our results show that RDFGraphGen is scalable and can generate small, medium, and large RDF graphs in any domain.
