Modular System for Recording and Managing Digital Evidences
Zeman, David ; Dzurenda, Petr (referee) ; Malina, Lukáš (advisor)
This bachelor thesis addresses the issue of security threats in cloud services and their general solutions. Furthermore, the output of this thesis is a proposed solution for log management and storage. This issue is addressed by using software from Grafana Labs publisher which include Promtail, Loki and Grafana. In the introduction, the basic concepts dealing with cloud services and their general security are established. The following section discusses Nextcloud and its security features and the external applications that provide Nextcloud security. The next chapters are an introduction to Docker and also an introduction to logging and its usage. Finally, the actual design of the log management and storage solution is addressed by the aforementioned software from Grafana Labs.

Vulnerability testing of cloud solutions by Slowloris attack
Šrámek, Michal ; Sikora, Marek (referee) ; Šeda, Pavel (advisor)
This bachelor's thesis addresses the issue of distributed Slowloris attack implemented in the Apache JMeter module. This module is then used to demonstrate the vulnerability in the Microsoft Azure cloud environment. The outcome of the thesis is an extension of the module, enabling testing from multiple IP addresses. The SlowHTTPTest tool, which the module utilizes for the attack, is also modified. In the introduction, the basic concepts related to cloud services and their classification are established. This is followed by chapters defining the current security threats to the cloud and how they compare between the three largest cloud providers. The technologies and configurations used in Azure environments are also described. Finally, the thesis focuses on modifying the attack module to support multiple addresses and tests it on both local and cloud infrastructures.

Guideline for assessing security risks arising from adoption of a cloud platform
Tomčová, Zuzana ; Bruckner, Tomáš (advisor) ; Vagner, Vlastimil (referee)
This thesis focuses on assessment of IT risks related to company's adoption of a cloud ser-vice. The goal of the thesis is to identify generally applicable set of IT risks, which will serve as a basis for the proposed risk assessment guideline. The work is organized as follows: Introduction and literature review is presented in the first chapter. The author provides theoretical background supporting better understand-ing of the topic in the Chapter two, where concept of the cloud computing and IT risk are described. A qualitative questionnaire is introduced and results of the participants' re-sponses are depicted in the third chapter. Following chapter provides a risks categoriza-tion representing a base for the proposed cloud oriented IT risk assessment guideline. Subsequently, validation of the guideline in form of its practical application on a company undergoing the decision-making process towards cloud solution is summarized in the Chapter five. Second last chapter describes standards and certifications in an area of coud information security. Finally, Chapter seven summarizes and concludes the findings outlining opportunities for future work and possible improvements in this area.
