Implementation of Honeypot tool for monitoring and analysis of network attacks
Němeček, Ladislav ; Červenka, Vladimír (referee) ; Bartl, Milan (advisor)
The goal of this thesis is to describe and categorize the malicious software. Thesis deals with the network attacks and the protection against them as well as how to detect and analyze the attack by the eligible tools. The next part of the thesis deals with the honeypot topic and the possibilities of detection using this software, specifically then the Argos tool. The installation, usage, and the methods of detection of the tool are also being described. The next chapter describes how to secure the honeypot against abuse. Last but not least, the thesis also contains the results of the network monitoring, attacks on the honeypot, and describes the log files used by Argos to interpret the results of the attack detection.

Analysis of Security Incidents from Network Traffic
Serečun, Viliam ; Grégr, Matěj (referee) ; Ryšavý, Ondřej (advisor)
Analýza bezpečnostních incidentů se stala velmi důležitým a zajímavým oborem počítačové vědy. Monitorovací nástroje a techniky pomáhají při detekci a prevenci proti tímto škodlivým aktivitám. Tento dokument opisuje počítačové útoky a jejich klasifikaci. Také jsou tady opsaný některé monitorovací nástroje jako Intrusion Detection System nebo NetFlow protokol a jeho monitorovací software. Tento dokument také opisuje konfiguraci experimentální topologie a prezentuje několik experimentů škodlivých aktivit, které byly detailně kontrolovány těmito monitorovacími nástroji.

Detection of Slow HTTP DoS Attacks
Jakubíček, Patrik ; Kováčik, Michal (referee) ; Bartoš, Václav (advisor)
This thesis deals with the detection of Slowloris attack. Based on the findings a detection module for Nemea system is implemented. It analyzes flow records and performs attack detection. Tests have verified that the module can work in real deployment and detect Slowloris attack quite successfully.

Analysis and Demonstration of Selected Network Attacks
Jirásek, Jakub ; Trchalík, Roman (referee) ; Očenášek, Pavel (advisor)
The aim of this Bachelor thesis is to describe and realize selected network attacks which are taught at the FIT, Brno University of Technology. The thesis includes demonstration exercises that can be used for teaching computer network security. First part of this work discusses theory for each attack and possible security solutions. In the second part the practical realizations (for each network attack) are described.

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.

Analysis and Demonstration of Selected Network Attacks
Gregorová, Pavlína ; Trchalík, Roman (referee) ; Očenášek, Pavel (advisor)
In this Bachelor thesis there are described network attacks which focus on network a computers issues. Attacks are aimed at operation system Windows and its security faults. The aim of this Bachelor thesis is also to prepare materials for lab of course called Security and Computer Networks, which is taught at the Faculty of Information Technology in the University of Technology in Brno.
