End Users to be connected through only HTTP/HTTPS

Hi Experts ,

I have a requirement where the End user can only be connected to SAP HANA from HTTP/HTTPS.  I don't want user to get connected from HANA STUDIO.

I can't create the restricted user as restricted user can insert a row in database or can change anything in database. So the restricted user will not work for me.

Any help on these is highly appreciated.
