Network Scanner for PowerShell
Sabota, Dominik ; Šeda, Pavel (referee) ; Martinásek, Zdeněk (advisor)
This study focuses on the development and implementation of a network scanning tool for the scripting language Powershell version 5.1 and higher. This tool, named Oculus, was specifically designed for the use of sophisticated network scanning methods during penetration testing and other security audits, thereby becoming part of the broader context of cybersecurity. Within the set requirements and limitations, the Oculus tool was successfully implemented. This work thoroughly analyzes the process of development and implementation of this tool, its limitations, and their impact on overall effectiveness, which is subsequently tested and evaluated. Although the development process brought certain challenges, the testing results confirmed that the Oculus tool provides valuable outputs, thereby confirming its usability in the matter of improving cybersecurity.

Software Development with Continuous Delivery
Molnár, Dávid ; Rychlý, Marek (referee) ; Křivka, Zbyněk (advisor)
Purpose of this work is to make the reader familiar with the principles of Continuous Delivery. Among them belongs automated deployment, frequent and repeatable delivery, versioning of applications and infrastructures configuration. These principles allow the develop-ment team to deliver the product very effective and ensure that customers get the ordered product in time and the fastest way possible. In the focus is the Windows platform, automatization and encryption of sensitive data. We will learn how to solve the problem of versioning relational databases and how to ensure working migration of database schema and data. Part of the work is a description, how to introduce Continuous Delivery in a team.

Efficient Transport of Electronic Mail with Microsoft Exchange Plugin
Jakubis, Tomáš ; Homoliak, Ivan (referee) ; Kováčik, Michal (advisor)
This project discusses optimization of e-mail and SMTP traffic in proprietary product of Microsoft Exchange 2013 in regard of marine industry. The goal is at first to analyze the requirements of this service on slow and unreliable network connections, SMTP traffic and then the product itself. Afterwards it defines specification for the final product and prepares the test environment. Design and implementation of transport agent using Exchange Management Shell is described for synchronization of two installations of Microsoft Exchange 2013; and focuses on emerged problems during the development, discusses different approaches and possible solutions. Testing shows various shortcomings of found solution. Finally, analysis of final solution shows possible future improvements and a need of security upgrade before applying to production environment.

Analysis of Scripts for Use in Clustering
Planička, Michal ; Burgetová, Ivana (referee) ; Křivka, Zbyněk (advisor)
This paper deals with the analysis of various script types and the extraction of traits which can be used for the cluster analysis performed by Clusty service. A file containing source code of the script serves as an input of the analyzer. The file is decoded and its content is then used for identifying the script type. If the script type is successfully identified, the analysis of the source code will be performed. The result of the analysis is a collection of traits which is then represented in the desired format (e.g. JSON). There are five supported types of scripts: JavaScript, VBScript, PowerShell, Python and batch file. The analyzer is designed such that support for new script types can be added.

Information System Generator
Falhar, Radek ; Hanáček, Petr (referee) ; Jurnečka, Peter (advisor)
Goal of this work is to design and implement too for passive code generation for specific information system framework. This framework is ZeroFramework that is targeted at client-server development of applications running on .NET platform. For code generation, T4 Scaffolding library is used, which allows to divide code generation logic into separate parts (scaffolders). This work is mainly concerned with design and implementation of those scaffolders and their linking with T4Scaffolding library. Results of this work are templates and logic for generation of files and classes, which implement logic needed for display, adding, modification and deletion of specific database entity.

Extensible Provider for Windows Powershell
Závišek, Josef ; Ježek, Pavel (advisor) ; Obdržálek, David (referee)
This thesis deals with the design and implementation of an extensible provider for Windows PowerShell. This provider allows registering the adapters which provide access to various data stores. The thesis gives an introduction into PowerShell and outlines how to realize new extensions. It then elaborates the architecture of the provider in detail. Next part is devoted to the design and implementation of the adapter for compressed files. For this purpose, the SevenZip library is used which had to be adapted for the use from C# language. Therefore, the thesis also includes description of the wrapper allowing the library utilization from the managed code.
