Detection of attacks targeted at web applications
Jégrová, Eliška ; Gerlich, Tomáš (referee) ; Martinásek, Zdeněk (advisor)
This thesis is dealing with vulnerabilities of web applications. The aim of the work is to create tools for attack detection of certain attacks, specifically Same Origin Method Execution (SOME), XML Signature Wrapping attack, XPATH Injection, HTTP Response Smuggling and Server-Side Includes (SSI) injection. Another aim is to create logs that display detected attacks. In the first part, the theory is analyzed and vulnerabilities of chosen attacks are described including their misuse. In the next section there are web application implemented which contain vulnerabilities for successful execution of the attacks. Furthermore, in Python language detection methods are designed and developed for these attacks, which are accompanied by a log entry.

Determination of waterproofing screens efficiency in various types of building materials exposed to capillary wetness
Červenka, Martin ; Dohnálek,, Pavel (referee) ; Drochytka, Rostislav (advisor)
Increased moisture of masonry occurs mainly in older buildings. In some cases these problems arise even in new buildings. This issue should be properly treated and process of rehabilitation of the building must be executed. Humid walls can be treated by chemical injections, which is nowadays quite extensive and widely used method. Unlike mechanical methods humid walls in the implementation of chemical grouting does not need a major redesign and thus is friendly to the construction of the object. The main objective of this thesis is to establish a methodology for testing the injection materials, which will include a selection of ideal injection gel.

Laboratory testing of hydroinsulating injection gel´s efficiency in dependence on state of various building materials
Miková, Lenka ; Dohnálek,, Pavel (referee) ; Drochytka, Rostislav (advisor)
Nowadays the use of chemical gel injection for humid masonry provides many benefits. If we consider the financial aspects of this kind of remediation of humid masonry, we can say that this method is least expensive and time-consuming. In comparison with other remediation methods major interventions into the structure is not required, which could result in deterioration of the structural analysis of the works and the consequent need of special machinery, which subsequently increases spent effort and resources. There is also need for additional screens easily applied to walls breached by rising damp and this need is also required for research in dealing with this issue. Only a standard regulation dealing with remediation of wet masonry using chemical injection is directive WTA 4-4-04 / D – Injection of masonry against capillary moisture. From this point of view there is a clear need for further development in this area.

The development of grouting for additional sealing of embankment dams
Michalčíková, Magdaléna ; Klablena,, Petr (referee) ; Drochytka, Rostislav (advisor)
Seal of sand or gravel by chemical injection is known and used for a long time. Chemical grouting are however expensive and sometimes the use of cement does not lead to desire effects. So it is trying to find new materials and methodologies injection arrangement works. To achieve savings of chemical products are added to a mixture clay and cement. Clay-cement grouting mix are used not only in order that they are better quality, but also because in this way proposed mixtures have a tendency to penetrate better into incoherent sediments that need additional sealant of chemical injection. For further possible reductions of economic terms the mixture is trying to replace the classic clay. As a suitable substitute for classic clay is to a certain extent the use of secondary raw materials. Above all it is fly ash. As a part of my thesis I deal with the appropriateness use of these materials and examining their properties in the mixture. It was found that by using fly ash were improving consistency of the fresh mixture, reducing the amount of water-cement ratio and reduce shrinkage of the mixture. On the other hand, by using fly ash has been increasing decantation, permeability atc. In the next stage of my work was examined the influence of the quality of cement, lime and liquefaction in the mixture. The aim of thesis is to propose the optimal injection mixture for additional sealing earth dams.

Experimental testing of hydroinsulating injection screens efficiency in dependance on properties of building materials
Červenka, Martin ; Černý, Vít (referee) ; Drochytka, Rostislav (advisor)
The most of the buildings are almost always faced with moisture in our climate. In the past, the humidity was reduced and conducted only by mechanical methods. Over time, chemical wet masonry method also known as chemical infusion curtain was invented and introduced into practice. This method involves the creation of boreholes at a selected height of humid masonry. These boreholes are impregnated with special solutions. These solutions in humid masonry fill pores in the field of boreholes and thanks to this subsequence the monolithic waterproofing curtain is created. The objective of this work is to determine the methodology for verifying effectiveness of various types of waterproofing injection curtains depending on the properties of the various types of building materials.

Rehabilitation technology of embankment dams by using suitable types of waste
Michalčíková, Magdaléna ; Kulísek, Karel (referee) ; Drochytka, Rostislav (advisor)
The subject of this work is to find an optimal technology for repairing existing embankment dams with emphasis on simplicity and ecological scalability. Next, secondary energy and waste materials will be evaluated as a partial replacement of a quality montmorillonitic clay. The aim of this will be to maximize the use of these waste materials. In the end a selection of materials for the locality will be made. The use of appropriate types of waste for repairs of embankment dams with clay based grouting compound technology has a great potential, especially with those dams that are not fulfilling their function due to their age.

Draft Curtains new Ways of Waterproofing and Assessment Methodologies
Miková, Lenka ; Dohnálek,, Pavel (referee) ; Drochytka, Rostislav (advisor)
Gel injections are progressive and more and more widespread technology for wet masonry rehabilitation, which finds its use due to working simplicity, and final effectiveness. In their application is not necessary to use strong destructive methods on construction and functionality of the final waterproofing is at a very high level. But the actual application of these technologies has technological limitations, and therefore arose in construction practice need of research new gel infusion with additional parameters and added functionality. Given the lack of a uniform methodology for such complex research process, the main aim of this thesis is proposal for methodological process for the research of new gel materials, and their later efficiency verification in the construction practice.
