Mészáros, Jan ; Buchalcevová, Alena (advisor) ; Čermák, Igor (referee) ; Doucek, Petr (referee) ; Jirovský, Václav (referee)
This dissertation thesis is dedicated to on-line services security management from service provider's and service consumer's viewpoints. The main goal is to propose a framework for on-line services security risk management, to develop a supporting software tool prototype and to validate them through a case study performed in a real-world environment. The key components of the proposed framework are a threat model and a risk model. These models are designed to fit specific features of on-line services and the surrounding environment. A risk management process is an integral part of the framework. The process is suitable for frequent and recurrent risk assessments. The process comprises of eight steps, related roles and responsibilities are defined for each step. The process execution results in identification and execution of proper tasks which contribute to treatment of identified security risks and deficiencies. Documentation and reporting of an overall level of on-line services security over time is possible if the process is executed on a regular basis. The proposed framework was validated through a case study performed in a large enterprise environment.

The third section provides a brief definition and classification of electronic payment systems. The fourth section presents a survey analysis using payment preferences of the Czech e-shops to see what payment methods they offer, which one they prefer and why. Especially if they enable the payment with the payment card and what led them to approve that, or vice versa discouraged them. The fifth part is based on a research from the fourth chapter and its aim is to evaluate the most widely used payment gateway in the Czech Republic. The sixth part deals with the paying preferences of a customer; which method are they using the most, what is their most favourite method and what are the barriers when paying with payment cards on the Internet. Objective of this thesis it to evaluate, based on analyses from customer and merchants point of view, online payments and payments with the payment card.
