Šebák, Ctibor ; Matějka, Martin (advisor) ; Novotný, Ota (referee)
This bachelor thesis is focused on the use of metadata in an environment of Self-Service Business Intelligence. Metadata are structured data that contain information used to de-scribe other data. They contain information about the origin, purpose, location, content and other properties of said data. The main advantage of the self-service BI tools lies in the fact, that the end user customizes the outputs of said tools (reports, data visualizations, etc.) to his own liking. The aim of this thesis is to briefly explain and define the concept of Self-Service Business Intelligence and the concept of metadata, to describe the purpose and benefits of using business metadata. Furthermore, to explore the possibilities of selected tools in context of metadata, more importantly - business metadata. The main contribution of this work is to reveal the possibilities of working with business metadata for selected tools and its empiric testing.

Traffic detection and analysis using SSL/TLS
Hutar, Jan ; Dvořák, Jan (referee) ; Smékal, David (advisor)
This diploma thesis deals with a detection and analysis of secure connections of electro- nic communication through SSL/TLS protocols. The thesis begins with introduction to SSL/TLS protocols. Thereafter, an analysis of messages used to establish secure con- nections using STARTTLS and postal protocols SMTP, POP3, and IMAP was made. Metadata detection and extraction of secured simplex and duplex connections take place using deep packet inspection tools. The tool of choice is the nDPI library from the Ntop project. The library was extended to detect the connections and extract the metadata based on studies and analysis of transmitted messages. Finally, testing is performed on a training data set and a basic analysis of acquired metadata is made.
