Security and Privacy for Mobile and Remote Staff
Security and privacy for your mobile and remote staff requires careful planning. Besides encrypted communications, it's also best to configure their remote access equipment to use Internet resources not subject to logging or snooping by their access providers.
For example, DNS, the function used in the internet to locate resources, is one way that third parties look for points of entry into your critical business IT infrastructure. You can reduce that risk when you configure the equipment assigned to your mobile workers to use an anonymous public DNS service, like the one provided by Verisign. Then they don't end up accidentally using the DNS provided by the hotel, restaurant, airport, or worse, a hacker's fake wireless access point that's pretending to be one of those.
Verisign also has one of the easiest IPv4 DNS addresses to remember: 64.6.64.6
64.6.65.6
