Internet access, according to the NATO Open Source Intelligence Handbook, is not simply a matter of gaining direct access at the best possible bandwidth, but also requires a combination of knowledge about how to discover and discriminate what can be found; and how to do so anonymously if operational security considerations demand anonymnity.

One example of a service providing for anonmyous Internet access is Anonymizer.
