There is an option they supply the switch too.
The first thing that came to mind is security issues since we are connecting
Internet and Local Network to the same switch inside the network.

That's like saying there is a security risk in running two phonecalls in the same T1/E1. They're logically separated, it's commonly done.

The question is: Is this a common practice? How do you handle with this scenario?

Usually I'd say that the ISP will solve the handoff by having a switch or media converter to give you one port per service, but using vlans for logical separation has been pretty much standard procedure for 10 years in a lot of places.
