 ## Security
-   Being a small GUI framework for Perl 5 desktop applications, PEB executes only Perl scripts distributed with the browser binary. All Perl scripts executed by PEB are treated as ordinary desktop applications with normal user privileges. A reasonable set of security restrictions are implemented in both C++ and Perl code, but they do not constitute a sandbox for Perl scripts within PEB. A PEB user can not endanger the opreating system, can not fall victim to remote or arbitrary Perl code, but still has access to all data he or she rightfully owns.

 **Security features based on C++ code:**
 * PEB can not and does not download remote files on hard disk and can not execute any Perl scripts from remote locations.
 * Users have no dialog to select arbitrary local scripts for execution by PEB. Only scripts within the ```{PEB_binary_directory}/resources/app``` directory can be executed if they are invoked from the PEB pseudo-domain: ```http://perl-executing-browser-pseudodomain/```.
