It might be similar to staid, but it's not the same as static.

I'd contend that when it comes to the web, by default you generally
allow new content, whether you like it or not and may at some time
later decide it is bad.

I'll argue that you don't have control over what traverses it - in terms
of content. You might control who connects to what.

I don't think time makes any difference. Things need to be forced
through peer review with security analysis as the primary objective
of evaluation. Put a bunch of Microsoft programmers in a room and
it won't matter if you give them 6 months or 6 years, they'll still
come up with something insecure at the end. The only difference
the time will be the number of useless features.
