The aim of this master's thesis is a design and implementation of a program for finding security and operational deficiencies of network devices and afterwards, resolving them by generating corrective configuration. Due to a lack of security and misconfiguration, there are a lot of devices exposed to the risk of a security incident. Therefore, the program compares settings with various standards, recommendations, and best practices and generates a report with findings. Afterwards, deficiencies can be eliminated by automatic resolution or manually if automatic resolving is not possible. The program uses regular expressions to find problem settings in previously exported configurations. Implementation is written in Python, and YAML markup language is used too. Another output of this thesis is a checklist, which can be used for the creation of future modules for support of other network device vendors and thus extend the program.

I denna rapport undersöks WPS-funktionen då det uppmärksammats säkerhetshåli den. Intervjuer, tester och observationer har gjorts för att undersöka problemenmed WPS. De tester och intervjuver som gjorts indikerar att säkerhetsbristen i WPS-funktionen har säkrats upp med extra funktioner. / In this report the WPS-function is evaluated due to the vulnerabilty of the protocol.Interviews, tests and observations have been conducted to evaluate the problems withWPS. The tests and interviews conducted indicates that the vulnerability of the WPS-function has been secured with extra functions.

With the development of Wi-Fi networks, Wi-Fi connection become a very important part of people‟s life, it seems that Wi-Fi networks are everywhere, especially in China. However, Wi-Fi networks not only bring convenience to users, but also bring some security threats. Nowadays, Wi-Fi security problems become increasingly acute. This thesis investigates the differences between male and female users regarding Wi-Fi network security. By distributing a questionnaire in China, specific questions have been asked about key factors within the area of Wi-Fi security. The questions focus on the usage situation, information security awareness and the knowledge level in Wi-Fi related fields. The found result is: Wi-Fi security issues are more prominent for female users than for male users.
