So if one wants to create a really nasty, largely untrackable problem,
one just needs to mount a set of attacks that last 3-4 minutes at a time?
This is a very bad band-aid. The solution is amazingly simple - make it
uneconomical to have unprotected networks, the same way as it is
uneconomical for businesses that rely on internet for critical
communications not to have a firewall in place when purchasing business
interruption insurance.
