ISMS Implementation Status Assessment
Černoušek, Robin ; Veselý Jindřich, Ing., MBA (referee) ; Sedlák, Petr (advisor)
Bachelor's thesis deals with the issue of information security management system and evaluation of the current state using a created tool. The theoretical part contains the basic principles and concepts of the whole work. The chapter on the analysis of the current state introduces the organization and describes the current state of its information security management system. The actual design of the solution is a tool in the form of an Excel spreadsheet, which will allow an analysis of the current state of the ISMS implementation level in the company.

Small Company Mobile Security
Válka, Radek ; Novotný, Vít (referee) ; Ondrák, Viktor (advisor)
In the course of the work, an analysis of security issues with the use of mobile devices in a small company is created. Based on this analysis, are identified risks that could have an impact on the security of the company's information due to malicious code on the mobile device or unauthorized access to the mobile device. To eliminate or reduce these risks, are proposed safety measures inspired by the measures in the ČSN ISO/IEC 27002 standard, on which the bachelor's thesis is focused.

Simulating information security management within a university environment
Hložanka, Filip ; Martina,, Chitu (referee) ; Sedlák, Petr (advisor)
This diploma thesis is concerned with simulating information security management within a university environment. It is divided into three parts. The theoretical part focuses on describing the assets which could be part of a faculty network, attacks that could target it, security processes which could protect it and users that are active within it. The analytical part then applies these segments on a real faculty network. Based on this analysis, a set of specific assets, attacks, security processes and other tasks is created in order to simulate a simplified version of the analyzed network using a sophisticated cybernetic polygon. The security of the network is then assessed after several iterations of the simulations. Its parameters are adjusted in the effort to increase its security and the module is tested on an academic employee in order to assess its effectiveness. The conclusion evaluates the possibilities of increasing the security of the simulated network as well as the usability of the cybernetic polygon in practice.

Implementation of standard ISO 27701 in the company using Gap analysis
Vicen, Šimon ; Konečný, Martin (referee) ; Sedlák, Petr (advisor)
This thesis analyses current state of the system for implementation of standard ISO 27701: 2019 extention. This standard extends already established standard ISO 27001. The thesis evaluates set of controls to the requirements of standard ISO 27701: 2019. Theoretical part contains information regarding the information security, describes a set of ISO 27000 standards as well as European and Czech legal acts related to information security. Following analysis of the company is performed with the application of security measures while implementing the extension standard ISO 27701. Contribution of this thesis is evaluation of the analysis which results from implementation of recommended standard to address the increased number of security threats and the protection of security information.
