Network worms spread widely over the global network within a short time, which are increasingly becoming one of the most potential threats to network security. However, the performance of traditional packet-oriented signature-based methods is questionable in the face of unknown worms, while anomaly-based approaches often exhibit high false positive...
Visualising complex data facilitates a more comprehensive stage for conveying knowledge. Within the medical data domain, there is an increasing requirement for valuable and accurate information. Patients need to be confident that their data is being stored safely and securely. As such, it is now becoming necessary to visualise data patterns and tre...

As the complexity and the scale of networks continue to grow, the management of the network operations and security defense has become a challenging task for network administrators, and many network devices may not be updated timely, leaving the network vulnerable to potential attacks. Moreover, the static nature of our existing network infrastruct...
Network Functions Virtualisation (NFV) is a novel paradigm for softwarisation of network functions that allows an operator to leverage large scale virtualisation to enhance availability and flexibility of typical network and security services offered to end users. Virtual Network Functions are proposed as an alternative to traditional hardware appl...
At present, distributed systems have been widely used, and a lot of research has been done on the reliability of distributed systems. However, trusted 3.0 based distributed system node trust behavior recognition research is still relatively rare. This paper focuses on the identification process and evaluation method of distributed node trust behavi...
The advancement of the internet across the globe has made computer users implement several ways of protection against possible network threats. The goal of this thesis is to analyse vulnerabilities and threats that may occur in a home network and design a vulnerability classification for home users with the help of Kali Linux. The classification is...
Účelem této práce je vytvořit nástavbu aplikace Snort umožňující přehlednou analýzu logů prostřednictvím webového rozhraní, které bude schopné provozu i na routerech s relativně malým výkonem. V úvodu práce je čtenář seznámen s nejznámějšími systémy pro odhalení průniku, jejich funkcemi a konfigurací. Následuje porovnání již existujících rozhraní p...
This article consolidates analysis of established (NSL-KDD) and new intrusion detection datasets (ISCXIDS2012, CICIDS2017, CICIDS2018) through the use of supervised machine learning (ML) algorithms. The uniformity in analysis procedure opens up the option to compare the obtained results. It also provides a stronger foundation for the conclusions ab...
Keeping users sensitive information secure and private in todays network is challenging. Networks are large, complicated distributed systems and are subject to a wide variety of attacks, such as eavesdropping, identity spoofing, hijacking, etc. What is worse, encrypting data is often not enough in light of advanced threats such as side channel atta...
Visible Light Communication (VLC) uses light-emitting diodes to provide wireless connectivity in public environments. Transmission security in this emerging channel is not trivial. Chaotic modulation techniques can provide encryption directly in the physical layer based on the random-alike evolution and strong synchronization prospect given by dete...
