Installing security updates

[T o n g <mlist4suntong@yahoo.com>]

Hi,

Is there any easy way to installing only the security updates? 

My box maintaining strategy is, the least maintenance possible the 
better. E.g., I only want to upgrade the minimum set of packages. So of 
all the packages that I need to upgrade, I only want to upgrade those 
security updates. How can I do that? 

I did some searching, seems everyone talking about automated security 
updates [1], [2]. But I don't want it automated, I don't want to upgrade 
every packages and I don't want to subscribe to the security mailing 
lists just to get the security update packages list. So,

Is there any easy way? 
Will the approach work for Ubuntu as well?

Thanks
