Generator of low-rate DoS attacks
Kaiser, Michal ; Gerlich, Tomáš (referee) ; Sikora, Marek (advisor)
The bachelor thesis is focused on the implementation and issues of Low-rate DoS attacks, where based on this information obtained during the compilation of the bachelor thesis, Low-rate DoS attack generators called NewShrew and LoRDAS are constructed. The reader will be introduced to the general issues of DoS attacks, their operation, and the exploitation of network communication, where these basic attacks will then be divided according to their network flow characteristics, and the Low-rate attacks will be described in more detail. After the theoretical introduction, the NewShrew and LoRDAS attacks are described. Subsequently, the methods of their detection and defense techniques will be introduced. Generators of these attacks are implemented in the Python programming language. These attacks will then be tested on test networks. The result of the thesis will be NewShrew and LoRDAS DoS attacks that attempt to make a web server inaccessible, results of correct settings of attacks, and also detection and prevention system are proposed.

The issue of RTO and RPO in business continuity management
Salai, Viktor ; Bruckner, Tomáš (advisor) ; Martanová, Kateřina (referee)
This thesis is concerned about Business Continuity Management with the focus on determination of the RTO and RPO parameters. The work is divided into two main parts. The first section briefly describes theoretical issues of Business Continuity Management in conjunction with IT Service Continuity Management. Then there are described various technologies that are currently used to ensure continuity and recovery of IT systems. In conclusion of the theoretical part, the work focuses on the process of Business Impact Analysis. This thesis thus offers a comprehensive view of main principles and benefits that these concepts have for company and how they should be integrated with each other. It provides an overview of various technologies, their link to RTO and RPO parameters and also the definition of steps of disaster recovery procedure. The work also briefly defines the basic procedure for determination of the RTO and RPO parameters, subsequent steps needed to design recovery solutions and analyzes various aspects which need to be considered when defining the parameters of continuity. The second practical part is based on the previous theoretically defined procedure and its aim is to analyze the data acquired during the questionnaire investigation in chosen company to determine the parameters of continuity for the applications in use and then suggest appropriate ways of addressing their backup and recovery. The result of this thesis is therefore a description of the analysis and practical application of methods for setting the parameters for continuity of information systems and the subsequent establishment of necessary measures.
