Does the default up2date verify the signatures or do I need to do some tweaking? If so, what do I do?

So the weak points in the update process are:
1. repository compromise
2. session hijacking
3. packet injection/spoofing
All fixed by configuring up2date and/or yum to verify GPG signatures.
Thanks Stan
