Pavel Kozak’s research while affiliated with Mendel University in Brno and other places

... In addition to civilian communication services, there is a growing demand for satellite radar for military surveillance and reconnaissance. Amid the uncertainty of localized wars, not only developed countries like the United States, European Union, Japan, and China, but also nations worldwide are increasingly focused on developing satellite communication and radar technology for national security [5,6]. Table 1 compares the electrical properties of major semiconductor materials [8], while Figure 2 illustrates the breakdown voltage characteristics as a function of cutoff frequency for semiconductor devices [9,10]. ...

... The analysis of performance errors showed moderate concern for all error types, with communication errors and misidentification/loss of separation scoring the highest. This highlights the importance of developing clear communication protocols and procedures to minimize the risk of errors (Gupta, Jain, & Vaszkun, 2016;Kozak, Platenka, & Vrsecka, 2022). Additionally, concerns regarding procedural errors, inattention/overload errors, and decision-making errors emphasize the need for ongoing training and support for controllers as they adapt to managing a more complex airspace environment. ...

... For example, a threat actor can use a physical interface (USB port) to attack a system without a network [26]. Due to being able to be carried out remotely network-based attacks make up most attacks observed today [27]- [29]. Table 4 illustrates and references the attack vectors detectable using network logs. ...

... Email phishing is a phishing type in which unsuspecting victim is tricked into divulging credential or sensitive information through email [10], [52]. Here the attacker sends phishing code either through email containing a phishing link or malware attachment in such a way that as soon as the victim clicks on the link [21], it will either redirect it to a phishing site or get the system infected by malware. Sensitive credentials getting by this mean can then be use by the attacker to commit series of cybercrimes against the victim or target organization including but not limited to remote malware installation, instigate Denial of service attack, Cyberstalking, identity theft, and can even be sold in the dark market. ...
