Detection of attacks on the L2 layer
Štefánik, Jaromír ; Martinásek, Zdeněk (referee) ; Gerlich, Tomáš (advisor)
Bachelor thesis is focused on cybernetic attacks on the second layer of the reference model OSI, namely: DHCP starvation, MAC flooding, Eavesdropping. The first, theoretical, part of the bachelor thesis is focused on the OSI model, types of cybernetic attacks and methods used by cybercriminals (attackers). In the practical part of the bachelor thesis an experimental workplace was set up (local network), the cybernetic attacks were realized, detection algorithms for given attacks were theoretically designed and programs designed to detect the given attacks were created.

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.
