Not true. There are a lot of defensive techniques that are simple,
inexpensive, have great FP/FN ratios, are low-bandwidth, are computation
and memory-efficient, maintainable/tunable, and scalable.
Don't believe the hype from the appliance vendors -- all they've done
is take all this stuff (and the open-source software that implements it)
and throw it in a box with a point-and-drool GUI for the incompetent
lusers who can't work at the command line.
