Some things can be made more or less secure on the IRIX machine. For example,
SAMBA allows you to restrict your network access, and some servers allow you
to compile in TCP wrapers. These use the /etc/hosts.allow and /etc/hosts.deny
files to control their access. 

You could also get a copy of RedHat's xinetd (I don't know if it will run
on IRIX or not, but it's worth looking). Xinetd replaces the usual inetd and
gives you much more configurability for security, etc.
