Hardening FreePBX

Sections: 

Hardening FreePBXThis script is a highly modified version of the AsteriskNOW hardening script a copy of which is here.  Some things were added.  Some were changed.  Some things were taken out.  Most importantly, it has been updated to work with newer versions of FreePBX where all the settings that used to be in amportal.conf are now in the Asterisk MySQL database.  As such, it is not compatible with older versions of FreePBX (anything before v2.9) which use the amportal.conf file.

Sections: 

This guide is a reference on how to create a RedHat Enterprise Linux v6 template for OpenVZ.
