table rights (consult the Keystone guide in Appendix C: The Bugzilla Database for some easy-to-use details)
that do not allow CREATE, DROP, RELOAD, SHUTDOWN, and PROCESS for user "bugs". I wrote up the Keystone
advice back when I knew far less about security than I do now : )

> Ensure you have adequate access controls for the $BUGZILLA_HOME/data/ and
$BUGZILLA_HOME/shadow/ directories, as well as the $BUGZILLA_HOME/localconfig and
$BUGZILLA_HOME/globals.pl files.
The localconfig file stores your "bugs" user password,
which would be terrible to have in the hands
of a criminal, while the "globals.pl" stores some default information regarding your
installation which could aid a system cracker.
In addition, some files under $BUGZILLA_HOME/data/ store sensitive information, and
$BUGZILLA_HOME/shadow/ stores bug information for faster retrieval. If you fail to secure
these directories and this file, you will expose bug information to those who may not
be allowed to see it.

> 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.

view the file "localconfig" in your web browser (ergo:
<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.
