a default backdoor because they want to make it easy for
their customers. It's almost like the cheaper the box the
less secure and the consideration seems to be that an unsavvy folk

If you look at the maintenance and
surveillance networks of a few large tier1's, you'll find
this "dummy" gear on those networks since they are cheap and
generalte no revenue. My last M/S design was dual rail
2XXX, 1600's for firewalls and frame terminations, which handled
console and monitoring for the cost of an ethernet port and
< 15K per facility. For the use, the capex matches as well as
