Implementation of NIS Backend for SSSD
Nykrýn, Lukáš ; Burget, Radek (referee) ; Zelený, Jan (advisor)
Tato práce se v první části zabývá představením technologií a nástrojů pro centrální správu a přihlašování uživatelů v GNU/Linux. Ukazuje využití adresářových služeb v síťové infrastruktuře, konkrétně služby NIS a její porovnání s dnes pravděpodobně nejrozšířenější adresářovou službou LDAP. Dále práce popisuje proces autentizace na klientských stanicích, konkrétně použití PAM a NSS a možné rozšíření celého systému zavedením cache díky démonu SSSD. Druhá část popisuje návrh a implementaci NIS provideru pro SSSD.

Security of Linux OS
Polách, Milan ; Vychodil, Petr (referee) ; Vymazal, Michal (advisor)
This thesis is focused on the possibility of better networking security operating system GNU/Linux with an appropriate set of rules Netfilter. There was established a program to allow easy configuration of rules for IP Address versions 4 and 6. This program not only allows to set individual rules, but also interfere with the newly required service and decide, how it will be further worked with. The first is the theoretical part describes the network communication with the model TCP/IP, the following is the introduction of Netfilter and outlining the local security. The practical part describes the various technologies and methods used for programming. The result of this work is easy to use program to set firewall rules for IP Address versions 6 with the possibility of deciding on the new established network traffic. The program is designed for new users of the operating system, who want to better secure their computer without the knowledge of Netfilter.
