alt Hacker NewsIn such a world you can say goodbye to any kind of free Wi-Fi, anonymous proxy etc., since all it would take to burn an IP for a year is to run a port scan from it, so nobody would risk letting you use theirs.
Fortunately, real network admins are smarter than that.
Pretty much. I think there's also a responsibility on the part of the network owner to restrict obviously malicious traffic. Allow anonymous people to connect to your network and then perform port scans? I don't really want any traffic from your network then.
Yes, there are less scorched-earth ways of looking at this, but this works for me.
As always, any of this stuff is heavily context specific. Like you said: network admins need to be smart, need to adapt, need to know their own contexts.
