Enforce Full or Selective Complexity on Passwords?

 @MattSpeller said: Rainbow tables are awesome at getting a percentage of a large number of passwords, against a single one there is probably a break even point where the complexity of your tables outweighs just brute forcing it. 
 $0.02 go for length over complexity any day.I think the biggest question would be "is this a one time attack" or do you "attack passwords on a recurring basis." Funny, but it becomes a "business of hacking" question rather than one strictly of the technology involved.

 @scottalanmiller Thanks!

 Saw this tonight in reference to requiring password changes every ninety days.

 Bring out the ol' bocket-o-slap and apply liberal servings to the post-it bandits.
