access to systems in the past. Please take these guidelines seriously, even
for Bugzilla machines hidden away behind your firewall. 80% of all computer

> At the very least, ensure you password the "mysql -u root" account and the "bugs" account, establish grant
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 : )

port 25 for Sendmail

>Do not run Apache as "nobody". This will require very lax permissions in your Bugzilla directories.
Run it, instead, as a user with a name, set via your httpd.conf file.</P

><P
> Ensure you have adequate access controls for $BUGZILLA_HOME/data/, $BUGZILLA_HOME/localconfig,
and $BUGZILLA_HOME/shadow directories.
The localconfig file stores your "bugs" user password,
which would be terrible to have in the hands
of a criminal. Also some files under $BUGZILLA_HOME/data store sensitive information.

> On Apache, you can use .htaccess files to protect access to these directories, as outlined
in <A

localconfig file, and <A
