SELinux application for Linux server security
Jirka, Michal ; Pelka, Tomáš (referee) ; Šimek, Milan (advisor)
This work is engaged in access control mechanism in GNU/Linux operating systems. At first discretionary and mandatory access control are compared and examine basic technologies based on mandatory access control. More closely is focused on project SELinux, whose generation of new rules is explained. Within the thesis is made application for logging evaluation and for writing new Type Enforcement rules.

Mandatory access control
Grepl, Miroslav ; Soumar, Michal (referee) ; Pelka, Tomáš (advisor)
This master's thesis describes the problems of SELinux, and the methods of creation of a proper security policy with a focus on the SELinux reference policy and its mechanisms. It designs the methodics of formulation of specific security rules, supplemented with the practical example of its application. Furthermore, it describes the available security rules commonly used for http, ftp and ssh services securing, their modification and practical utilization. According to the proposed methodology, these services are protected with their own security rules and both security methods are mutually compared and evaluated.
