                 Whether implementing a server-based or dedicated hardware-based VPN solu-
             tion, it is important to make sure that the VPN servers or devices are as secure as
             possible.This should always include changing the default passwords to strong pass-
             words, ensuring that the best encryption methods available for the implementation
             are being used, and making sure that the software and devices are up-to-date with
             the latest updates from the vendor.
