SQL Server Secure Communication

SQL Server Secure Communication

I am designing a C# application that will comunicate with na SQL Server
for data keep/fetch. This app is supposed to be used from within AND
without the local network where the server will be (ie accross offices or
even countries) so communicastion with the sever needs to be done over the
internet.
I have setup a few tests and everything works well but now it's time to
add security into the design.
With connections coming from the internet into their servers, my clientes
will want the communication between the cliente app and the SQL server to
be as safe as possible from net sniffers and such (ie, keep people from
listening in to the data being transfered or worse, get server access)
I have read somewhere some time way back (can't find the link anymore)
that SQL Server has na option for SSL connectio.
So my question is - Is this my best or even only option for security?
Where can i find information/code samples on how to implement this?
Before anyone goes there - i have googled this but got no luck beyhond the
information that an SSL connection option exists.
