I am not sure I would agree with either of the solutions presented in 
the thread. I understand that your systems need extra security. However, 
  there is security in terms of availability and security in terms of 
confidentiality. To rely on a system to be available, just by upgrading 
the kernel is not a good idea. glibc, module-init-tools, and other 
dependences might introduce problems to the system if you just upgrade 
the kernel, especially if you do development work (compilers, dev libs?)
You need a proper way to handle the dependencies for these things.

If your employer wants the best solution about keeping RHEL systems 
up-to-date in a secure way, that should provide a proper RHN Satelite 
Server. It is essentially an advanced proxy server that stands between 
your system  and the Internet and allows controlled upgrades. The 
procedure to obtain and setup this is given here:

and at the bottom you should find various whitepaper links that give you 
an idea about what to expect when you implement this.
