is absolutely no protection against system crackers versus using
any other user account. As a general security measure, I recommend
you create unique user ID's for each daemon running on your system

rest of your system.</P

>Ensure you have adequate access controls for the
$BUGZILLA_HOME/data/ directory, as well as the
$BUGZILLA_HOME/localconfig file.
The localconfig file stores your "bugs" database account password.
In addition, some
files under $BUGZILLA_HOME/data/ store sensitive information.
</P
><P
>Bugzilla provides default .htaccess files to protect the most
common Apache installations. However, you should verify these are
adequate according to the site-wide security policy of your web
server, and ensure that the .htaccess files are allowed to
"override" default permissions set in your Apache configuration
files. Covering Apache security is beyond the scope of this Guide;
please consult the Apache documentation for details.</P
><P
>If you are using a web server that does not support the
.htaccess control method,
<EM
>you are at risk!</EM
>
After installing, check to see if you can view the file
"localconfig" in your web browser (e.g.:
<A
HREF="http://bugzilla.mozilla.org/localconfig"
TARGET="_top"
> http://bugzilla.mozilla.org/localconfig</A
>
). If you can read the contents of this file, your web server has
not secured your bugzilla directory properly and you must fix this
problem before deploying Bugzilla. If, however, it gives you a
"Forbidden" error, then it probably respects the .htaccess
conventions and you are good to go.</P
><P
>When you run checksetup.pl, the script will attempt to modify
various permissions on files which Bugzilla uses. If you do not have
a webservergroup set in the localconfig file, then Bugzilla will have
to make certain files world readable and/or writable.
<EM
>THIS IS INSECURE!</EM
>
. This means that anyone who can get access to your system can do
whatever they want to your Bugzilla installation.</P
