The TCP/IP standard defines more than 65,000 ports for sending and receiving traffic. Of those, Bugzilla needs exactly one to operate (different configurations and options may require up to 3). You should audit your server and make sure that you aren't listening on any ports you don't need to be. It's also highly recommended that the server Bugzilla resides on, along with any other machines you administer, be placed behind some kind of firewall.
Many daemons, such
httpd or MySQL's
mysqld, run as either “root” or
“nobody”. This is even worse on Windows machines where the
majority of services
run as “SYSTEM”. While running as “root” or
“SYSTEM” introduces obvious security concerns, the
problems introduced by running everything as “nobody” may
not be so obvious. Basically, if you run every daemon as
“nobody” and one of them gets compromised it can
compromise every other daemon running as “nobody” on your
machine. For this reason, it is recommended that you create a user
account for each daemon.
You will need to set the
If your system supports it, you may wish to consider running
Bugzilla inside of a
chroot jail. This option
provides unprecedented security by restricting anything running
inside the jail from accessing any information outside of it. If you
wish to use this option, please consult the documentation that came
with your system.
