Any system that lets a cracker > hammer away with repeated attempts is the thing that is broken. I don't think it has to be as low as 3. It could be 100 or 1000, a restriction that a human will never hit, but a cracking program will hit almost immediately. This makes it easy to separate attackers from legitimate users, and take appropriate action against the attackers. Ban their IP address? Notify their ISP? Track their botnet and disable it? I'm not sure there are effective defenses. An alternative is to look for frequency of login attempts. More than 1 every second implies a bot, not a human. _______________________________________________ users mailing list -- users@lists.fedoraproject.org To unsubscribe send an email to users-le...@lists.fedoraproject.org
