Thesis (M.S., Computer Science)--University of Idaho, June 2015 | Web browsers are used frequently to access resources from the World Wide Web (WWW) however, they are vulnerable to various attacks which may affect specific applications or an entire operating system. The current administrative tools used for configuring browser setting in order to mitigate security vulnerabilities in browsers, follow different procedures to configure different browsers. This variance eventually increases the complexity for system administrators to analyze and configure similar security settings in all the browsers. In this thesis, firstly, we analyze and categorize secure browsing policies. Secondly, we argue that a set of common settings and a common configuration language for multiple browsers is needed. Thirdly, we introduce Open Browser GP: A Multiplatform and Multibrowser Policy Configuration tool that enables configuring the security related settings in three major browsers: Internet Explorer, Google Chrome and Mozilla Firefox, in Windows 7 and Windows 8 client systems.
