Secure Development Framework for Web Applications
Mazura, František ; Ovšonka, Daniel (referee) ; Barabas, Maroš (advisor)
This thesis deals with the theoretical analysis of vulnerabilities in web applications, especially the most frequent vulnerabilities of OWAST TOP 10 are examined. These vulnerabilities are subsequently analyzed for the design of a web application development framework and practically implemented in this framework to prevent the vulnerabilities or, if necessary, defend itself. The main goal of the implementation is to achieve such a framework so that the programmer of the resulting web application is protected to the utmost.

Implementation of ISMS in the Commercial Company
Dejmek, Martin ; Soška, Libor (referee) ; Sedlák, Petr (advisor)
This master thesis deals with the implementation of information security management system in the company. It summarizes the theoretical background in this field and uses it to analyze the current state of information security, as well as analysis and risk management and not least the actual implementation of ISMS in the particular company. This work also contains three groups of measures that reduce the impact of identified risks and which also implements an essential parts of ISMS.

Security exercises for ethical hacking
Paučo, Daniel ; Lieskovan, Tomáš (referee) ; Martinásek, Zdeněk (advisor)
This master thesis deals with penetration testing and ethical hacking. Regarding to the layout of the thesis there was prepared appropiate enviroment to realize Red/Blue team exercise, where Red team is in a role of the attacker and Blue team is in a role of defender of the network infrastructure. Whole infrastructure is implemented in a cloud virtual enviroment of VMware vSphere. Second part of the thesis consists of preparation and creation of the exercise to test web application security. Third part of the thesis is dedicating to the automatization of redteaming. Main focus of this master thesis is to demonstrate different attack vectors how to attack the network infrastructure and web applications and use of the defense mechanisms to avoid this kinds of attacks.

The Introduction of Information Security Management System in IT Enterprise
Riegl, Tomáš ; Sedlák, Petr (referee) ; Ondrák, Viktor (advisor)
This thesis deals with the introduction of information security management system in IT enterprise. It includes theoretical knowledge which are necessary for the understanding of this issue and their application for the analysis of the current state of information security, risk analysis and risk management. Last but not least for the actual implementation of information security management system in the company. The implementation of ISMS was divided into two phases. This thesis details the first phase.

Information security management system project
Kameníček, Lukáš ; Kotek, Luboš (referee) ; Fiala, Alois (advisor)
This diploma thesis analyses the current state of information security management in an organization. In the theoretical part of the thesis general concepts are described as well as the relations between risk management and information security, applicable laws and standards. Further, the theoretical part deals with the risk analysis and risk management, strategies, standard procedures and methods applied in this field. In the practical part a methodology is suggested for information risk analysis in a particular organization and appropriate measures are selected.

Design of methodology for vulnerability assesment
Pecl, David ; Martinásek, Zdeněk (referee) ; Gerlich, Tomáš (advisor)
The thesis deals with the assessment of security vulnerabilities. The aim of this work is to create a new method of vulnerability assessment, which will better prioritize critical vulnerabilities and reflect parameters that are not used in currently used methods. Firstly, it describes the common methods used to assess vulnerabilities and the parameters used in each method. The first described method is the Common Vulnerability Scoring System for which are described all three types of scores. The second analysed method is OWASP Risk Rating Methodology. The second part is devoted to the design of the own method, which aims to assess vulnerabilities that it is easier to identify those with high priority. The method is based on three groups of parameters. The first group describes the technical assessment of the vulnerability, the second is based on the requirements to ensure the confidentiality, integrity and availability of the asset and the third group of parameters evaluates the implemented security measures. All three groups of parameters are important for prioritization. Parameters describing the vulnerability are divided into permanent and up-to-date, where the most important up-to-date parameter are Threat Intelligence and easy of exploitation. The parameters of the impact on confidentiality, integrity and availability are linked to the priority of the asset, and to the evaluation of security measures, which increase the protection of confidentiality, integrity and availability. The priority of the asset and the quality of the countermeasures are assessed based on questionnaires, which are submitted to the owners of the examined assets as part of the vulnerability assessment. In the third part of the thesis, the method is compared with the currently widely used the Common Vulnerability Scoring System. The strengths of the proposed method are shown in several examples. The effectiveness of prioritization is based primarily on the priority of the asset and the security measures in place. The method was practically tested in a laboratory environment, where vulnerabilities were made on several different assets. These vulnerabilities were assessed using the proposed method, the priority of the asset and the quality of the measures were considered, and everything was included in the priority of vulnerability. This testing confirmed that the method more effectively prioritizes vulnerabilities that are easily exploitable, recently exploited by an attacker, and found on assets with minimal protection and higher priority.

Laboratory exercise that presents network attacks
Dostál, Adam ; Malina, Lukáš (referee) ; Martinásek, Zdeněk (advisor)
This work is focused on penetration testing of web applications. The theoretical part describes this issue and methodology. The work includes security organization "The Open Web Application Security Project" (OWASP), document OWASP Top 10 and the first 5 vulnerabilities of this document. The last part introduces linux distribution Kali Linux and the several most used penetration tools. The practical part consists of testing the first five vulnerabilities in the document OWASP Top 10 2013. It contains a description of the used SW for the realization of the attacks, virtual infrastructure and test of each vulnerabilities. From the practical part is created laboratory task "Penetration testing of web applications" and additional introductory task "Introduction into penetration testing".

Design of a smart meter testing methodology focusing on invasive testing
Biolek, Martin ; Sikora, Marek (referee) ; Lieskovan, Tomáš (advisor)
Bachelor thesis is focused on investigating the security deficits of smart meters through penetration testing. The theoretical part describes the standards that should be followed by smart meter manufacturers. This is followed by the practical part where the testing of two smart meter systems was conducted in order to discover their vulnerabilities. The result of the work is the exposure of one of the two systems of interest that requires significant security improvements before deployment of another version. A description of the vulnerabilities is included in the practical part of the thesis.
