[CentOS] Determine security updates

I'll put in a plug for a software project that I am developer/contributor
for, OpenVAS (Open Vulnerability Assessment Scanner).

http://www.openvas.org

If you configure OpenVAS to use a SSH enabled login account, it will tell
you which security patches you are missing.  If you do just a remote scan,
it will give you an incomplete list of missing patches.

It is cross-platform too.
