By saving security profiles to your computer you can later reuse these settings.
In this way you can in fact work with more than the three security profiles, and also copy settings from one profile to another.
Import is when you get a profile from your computer and copy it to the firewall.
Export is when you copy a profile from the firewall to your computer.
