enforce authentication and authorization for access to legitimate services.

Good point...and that's exactly why in some cases, especially in SOHO
and SMB oriented products, both hardware as well as software vendors can
be part of the security problem by advertising their products as the
definite solution to all security holes. Truely securing even a single
server or host connected to the Internet entails a lot more than just
blocking a few ports, let alone securing a network. By marketing "the
perfect solution" to no-too-clueful admins the actual security holes
only get bigger and harder to track.
