SSH Public Key Management in FreeIPA and SSSD
Cholasta, Jan ; Smrčka, Aleš (referee) ; Zelený, Jan (advisor)
SSH je jeden z nejpoužívanějších protokolů pro vzdálený přístup v Internetu. SSH je flexibilní a rozšiřitelný protokol, který se skládá ze tří hlavních součástí: SSH transportního protokolu, který obstarává důvěrnost, integritu a autentizaci serveru, SSH autentizačního protokolu, který obstarává autentizaci uživatelů a SSH spojovacího protokolu, který obstarává multiplexování více kanálů různých typů (interaktivní sezení, přesměrování TCP/IP spojení, atd.) do jednoho spojení. OpenSSH je jedna z nejrozšířenějších implemetací SSH. OpenSSH obsahuje SSH server, SSH klienty, generátor SSH klíčů a autentizační agent, který usnadňuje autentizaci pomocí veřejných klíčů. FreeIPA a SSSD jsou projekty poskytující centrální správu identit pro Linuxové a Unixové systémy. Tyto projekty sice v době psaní této práce přímou podporu SSH neobsahovaly, ale do jisté míry je ve spojení s OpenSSH používat možné bylo.

Design of security infrastructure for electronic archive
Doležel, Radek ; Lattenberg, Ivo (referee) ; Zeman, Václav (advisor)
This master's thesis deals with design of security infrastructure for electronic archive. In theoretical part is disscus about technical resources which are based on security services and protocols and methods which are used for protection. On basics of theoretical part is designed model of security infrastructure and it is built in laboratory. Model of security infrastructure is based on Open Source Software and as safety storages for private user authentication data are used cryptographic USB tokens. This master's thesis includes design and construction of real infrastructure of secured electronic archive. In each part of master's thesis is put main emphases on security and clear explanation from the beginning of desing of model of security infrastructure for electronic archive to finish of construction.

IP Phone Implementation on Development Kit ATSTK1000
Böhm, Karel ; Smékal, Zdeněk (referee) ; Sysel, Petr (advisor)
This thesis deals with the implementation of IP phone on development kit Atmel ATSTK1000. At the beginning, there is an introduction with properties, hardware and software equipment of the development kit which is used to development of embedded devices. The next part introduces with open sources IP phones, with their characteristics and requirements. The conclusion is devoted to cross-compilation of the selected IP phone and its operation on the development kit ATSTK1000.

Secure Remote Computer Management System
Heško, Peter ; Hranický, Radek (referee) ; Polčák, Libor (advisor)
Deployment and management of remote systems poses several problems. Their administration and monitoring is much faster and more cost-effective when done remotely than when physical access to the system is required. Software that allows this is in many cases not freely available or has limited functionality. In this work I deal with the analysis of available solutions and then design and implementation of an application that combines all the required features. The result is software that provides secure access to and monitoring of remote computers running Ubuntu 16.04.
