If I set security updates to download and install automatically, 
Software Updater will never show up. Instead updates are installed 
silently in the background.

Exceptionally, if the computer hasn't been used for a long time, it 
could happen that Software Updater actually asks me to upgrade. But the 
behaviour seems to be that, if there's a security update, to do all the 
updates in the background.

So as long as you have the computer configured to check for updates 
daily, and security updates to download and install automatically, any 
exploit shall get patched in the next boot.
