There really is no 'best'.

My advice:
Go with what you know.  For example:  If you are an Oracle DBA (or have them on staff), it makes sense to go with Oracle.

As far as security:
You typically don't have the database directly accessible from the Internet.  You also don't typically let clients have direct database access.

You create applications that allow users to retrieve/manipulate data.  In the Internet/Intranet world this is commonly done through Web Services.

App calls web service.  Web service calls database.

You can get VPN solutions from any of the major vendors of networking equipment (Cisco, Juniper, ...).

But ... accessing databases over the internet is doing something that databases aren't designed for. Your clients are very likely to experience performance issues. Database connections are designed for low latency/high bandwidth reliable LAN connections, not for high latency internet connections.

Going for webservices, as suggested by slightvw, may be a better solution because these protocols are designed for the internet. Of course your application must allow this.
