Hardening CentOS Image
Hello,
Not sure where to start here, but I have been tasked with hardening our CentOS images which currently install from Cobbler and vSphere ISOs. I can only imagine this is a RHCE requirement but I don't see it in my book.
Looking to remove a few packages and add some of our own that we use in advance. I guess I am looking for the Linux equiv of sysprep.
Anyone aware of a walk through on this process?

A good resource would be the Red Hat Enterprise Linux Security Guide available on the Red Hat site.
It covers most of securing a Server. -

I'm not sure if this is a certification related question, but generally speaking:
Start with minimal installation, and add packages later as per requirements. Disable all the unnecessary services and implement a tight iptables firewall (which is not a trivial task). Make sure you install updates regularly and systematically.
