Web information is most vulnerable to interception while it is "in the pipe" that is, en route from one part of the to another. You can substantially harden the pipe against would-be eavesdroppers by requiring the standard for transmitting information between FrontPage, Web browsers, and Web servers.
To require SSL for authoring
Note
If you require SSL for authoring, then authors who try to work on the web will get a message saying that they are required to use SSL, which they can choose in FrontPage.
