Analysis of possible threats in old OS Linux version
Chovancová, Emília ; Dejdar, Petr (referee) ; Tomašov, Adrián (advisor)
The bachelor thesis is focused on the security aspect of an older version of a Linux based machine. The document is split into a theoretical part which contains a description of what operating system, kernel, UNIX, GNU/LINUX and Linux OS are in general. Then the description proceeds to explanation of active and passive attacks such as replay, masquarade, denial of service, man in the middle or listening and analysing the network. Afterwards it continues with description of potentially vulnerable spots that are common on operating systems. With the help provided from scanning software, especially Nmap and Lynis, the document proceeds to the practical part which contains various types of successful and unsuccesfful attacks such as password recovery, denial of service, spectre, brute force of a password and cross-site scripting. The last part covers the protection against succesfull attacks and adds a little bit more of additional protection in general in a form of an ansible script.
