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.

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.

The Information Security Management in Company
Kalabis, Petr ; Sedlák, Petr (referee) ; Ondrák, Viktor (advisor)
This master thesis is focused on the design of implementation the information security management system in the company according to standards ISO/IEC 27000. First of all, it was described the theory of information security management system and it was explained the relevant terms and other requirements in the context of this issue. This assignment involves analysis of the current situation of the company and suggestions that lead to reducing discovered risks and bring improvement of the general information security.
