First of all, you should really update to CentOS 5.5 plus all the
additional package updates.
And then, there is a nice wiki page
http://wiki.centos.org/HowTos/OS_Protection
with lots of helpful information about your topic. Read it carefully,
and you will find a link to
http://www.nsa.gov/ia/_files/os/redhat/rhel5-guide-i731.pdf
with further tips to secure your system.
