I maintain a server hosting a fair number of WordPress blogs and I get inundated with brute-force password attempts.    In order to minimize the likelyhood of success of an attack, I have taken to limiting the number of login attempts I’ve customised some Fail2Ban rules to provide “overriding” lockout of accounts.
