Mobile Application for Network Scanning
Teuchner, Marek ; Bartoš, Václav (referee) ; Kováčik, Michal (advisor)
The subject of this bachelor's thesis is to design and implement an application for Android operating system that allows the discovery of all connected devices in a local network and to display information about it and all of its devices. The application would allow the user to assign a custom icon and a note to each device within the network. Logs and statistics are also collected by the application. In addition, it is possible to attack the selected device using various Denial of Service attacks.

Security of Testing Farm Service
Havlín, Jan ; Malinka, Kamil (referee) ; Drga, Jozef (advisor)
This thesis deals with security of Testing Farm Service in Red Hat company. Specifically, it is about unauthorized usage of testing machines for purposes which are not allowed. The need for implementing security measures comes from the fact that users are allowed to run arbitrary code on test machines as the user root. In the implementation part of the thesis, a monitoring agent was created and deployed to the testing machines of the production environment of the service. This system watches transmitted packets, system resources and configuration. Based on these observations, it creates metrics about the system behavior and sends them over to monitoring server Prometheus.

Detection of Network Attacks Using Tshark
Dudek, Jindřich ; Ryšavý, Ondřej (referee) ; Holkovič, Martin (advisor)
This diploma thesis deals with the design and implementation of a tool for network attack detection from a captured network communication. It utilises the tshark packet analyser, the meaning of which is to convert the input file with the captured communications to the PDML format. The objective of this conversion being, increasing the flexibility of input data processing. When designing the tool, emphasis has been placed on the ability to expand it to detect new network attacks and on integrating these additions with ease. For this reason, the thesis also includes the design of a complex declarative descriptions for network attacks in the YAML serialization format. This allows us to specify the key properties of the network attacks and the conditions for their detection. The resulting tool acts as an interpreter of proposed declarative descriptions allowing it to be expanded with new types of attacks.
