    Hackers try stuff all the time. It's their job. Your job is to allow the minimum possible level of access and keep your systems updated.

    For example, if you have GeoIP filtering licensed and your user base is in a known list of countries, then restrict public access to SSLVPN services to that list of countries.

    If you've got sensible password policies, keep things up to date and don't allow access from places that don't need it, then you can sleep easy.
