About site security (if available)

Your service provider configures the security environment in which your site is hosted. Depending on the security level assigned to the site, certain services for the site run in protected mode within the restricted environment of the site’s file system, technically referred to as a chrooted environment. This prevents you and the site users from accessing data or resources pertaining to other sites on the server.

Your site can be configured for one of the following security levels:

To ascertain which security level is configured for your site, contact your service provider.

High security

High security runs certain services, that are vulnerable to security breaches, inside the restrictive environment of the site's file system.

The services that are secured are:

CGI Scripts

CGI scripts can present security loopholes in two ways:

High security places cgi scripts inside a restrictive part of the site's file system.

Telnet/Secure Shell

Remote login services like Telnet or SSH allow users to interact with remote computers on the Internet. They can expose your system to denial-of-service attacks and enable hackers to run subversive code.

High security locks remote user logins (administrator and users of the site) to the restrictive environment of their home directories. When you or any of the site users connect to the site you are directly logged in to the home directory of your site, preventing view or access to any system wide resources from the site’s operating environment.


mod_perl and mod_php are modules that allow users to run scripts on the Web server, thus exposing your Web server to potential exploits.

High security disables the mod_perl and mod_php services for a site. Scripts using mod_perl or mod_php cannot be run on the site.

3.1 compatibility

3.1 compatibility offers a loosely knit security environment wherein remote login services are secured, but CGI scripts run in a vulnerable environment.

The following services are secured.

CGI scripts

CGI scripts are not locked in the site's file system. This compromises security but eliminates file sharing constraints posed by secured CGI scripts.

Telnet / Secure Shell

Telnet and SSH services are secured as in high security. Remote user logins (administrator and users of the site) are locked in the protective environment of the site's file system.

mod_perl / mod_php

mod_perl and mod_php services are enabled for the site. Your site can run scripts using mod_perl or mod_php.

Low security

Low security provides an open operating environment. You can share or access files (depending on file access privileges) residing on the server. Users of your site are, however, restricted to the home directory of the site.

Your site is also enabled to run mod_perl and mod_php scripts.

None of the following services are secured for the site.

CGI scripts

While CGI scripts reside within the site's file system, the administrator of the site can access or share system wide resources outside the CGI-BIN directory.

Telnet / Secure Shell

With low security, administrators can use the Telnet or SSH remote login service to traverse the file hierarchy outside the site's home directory. Users, however, are jailed to their home directory within the site.

mod_perl / mod_php

mod_perl and mod_php services are enabled for the site enabling site users to run scripts using these applications.
