That's actually a very good question. I am currently working on a public
FreeIPA demo on Red Hat OpenStack platform which I will make available in
upcoming weeks and have few pointers for you:
1) If you have DNS configured, make sure that your FreeIPA DNS does not pose as
open DNS resolver to avoid DNS amplification attacks.
Following extension to named.conf options should be a good start:
allow-transfer {"none";};
allow-recursion {"none";};
recursion no;
version "[Secured]";
rate-limit {
responses-per-second 15;
};
2) Prevention for NTP amplification attack
More info here:

Does anybody know about other precautions that should be made besides standard
hardening (SELinux, firewall, log audits)?
Thanks,
Martin
