Security inspection of network traffic
Kult, Viktor ; Havránek, Martin (advisor) ; Ladislav, Ladislav (referee)
Thesis topic concerns the issue of information security in corporate environments. Literature search includes information obtained by studying articles and literature in the field of information security. Resources were selected with a focus on the security risks, security technologies and legislative regulation. Attention is focused on technology that supports monitoring of communication flows in the data network. Overview of traffic operating a data network provides important information for the prevention or investigation of security incidents. Monitoring also serves as a source of information for the planning of the network infrastructure. It can detect faults or insufficient transmission capacity. The practical part is dedicated to implementation of the monitoring system in the real corporate networks. Part of the experience is the analysis of the network structure and choice of appropriate tools for actual implementation. When selecting tools, you can use the scoring method of multicriterial analysis options. The integration of the monitoring system is also the configuration of active network elements. Subsequent analysis of network traffic provides information about the most active users, most used applications or on the sources and targets of data transmitted. It provides a source of valuable information that can be used in case of failure on the network or security incident. The conclusion is a summary of the results and workflow.

Virtualization for the x86 platform
Müller, Pavel ; Kyselý, František (referee) ; Pelka, Tomáš (advisor)
A thesis describes a virtualization of x86 platform. In the first part the virtualization, its utilization and specific types of virtualization are described in a general way. The specific types of virtualization are full virtualization, paravirtualization, virtualization on core level, hardware virtualization and application virtualization. There is also described a general function of virtual machine, reasons of virtualization implementing, current development, focusing on future development and virtualization security. In the second part the thesis tries to find a solution with establishment charges of virtualization. To test purposes the following software programs were used. The first one is freeware benchmark Sandra from SiSoft company and second one is a software created on the basis of the thesis. For the tests the CPU overhead both an arithmetic-logical unit and a unit for work with numbers and floating decimal point, a RAM data transmission efficiency and a hard disk logging rate were chosen. The following test machines were described: VMWare, VirtualBox and Xen. In the third and the last part of the thesis is a description of network interface virtualization methods with a utilization of tun and tap system. In each particular step a virtual network interface creation and implementation are presented. Model situations of communication among virtual and physical machines with usage of these devices are described at the end of the thesis.

On the increase of cutting performance of thread cutting taps with coatings
Světlíková, Jitka ; Sliwková, Petra (referee) ; Píška, Miroslav (advisor)
This bachelor thesis deals with the process of cutting, the wear of cutting tools and the fact, that coating makes tools more durable and increases cutting power. The goal of the experimental part is to determine, compare and evaluate cutting features in the process of thread cutting with taps of different coatings. For the experiment invariable cutting conditions were chosen, the only variable is the type of used coating. The result of the experiment is the measurement of cutting torque dependent on time and the grade of the wear of cutting tools.

The Role of Imaging in Surgical Inflammatory Complications
KOPRDOVÁ, Eliška
The Role of Imaging in Surgical Inflammatory Complications Interventional radiology is a dynamic and fast developing specialization. Development of new methods and instruments extends possibilities of mini-invasive treatment of a wide range of illnesses. Introduction of a specific percutaneous drain in case of abdominal abscess in clinical practice counts among most important progress of 1980s concerning this field. The percutaneous drain is relatively fast and simple method and it belongs to urgent interventional operations. Indication for the percutaneous drain is a treatment or a palliative treatment of sepsis accompanied by an infected lesion. Most authors agree that there is no absolute contraindication of the percutaneous drain for pathological liquid collection. Therefore, this type of drain may be considered as a method selection. It is possible to execute it even before a possible surgical operation. The goal of my work was to assess retrospectively the experience of the Radiological Department of the Teaching Hospital in Plzeň Bory concerning this field within the selected period of time. For this reason, a single-purpose database has been created, which contains data of patients who underwent the percutaneous drain under the supervision of the CT or UZ within a certain period of time. Such data has been processed statistically. The work did not prove any of the hypotheses of mine that interventional techniques may in all cases substitute surgical operation while treating suppurative inflammatory lesions in the area of chest, abdomen and soft tissues. The percutaneous drain brings unquestionable advantages into clinical practice. Among most important ones, there are a removal of a surgical operation risk and of total anaesthesia, above all in the acute phase of illness. Simplification of post-operative care, shortening of the average hospitalization as well as economic advantages. This concerns a method that should always be considered as the first step among possible treatments of infected lesion.
