Banks, Arbitrary Password Restrictions and Why They Don't Matter
He turned to me and said, "Do you really think the only thing the bank does to log people on is to check the username and password?" Banks are way more sophisticated than this and it goes well beyond merely string-matching credentials; there's all sorts of other environment, behavioural and heuristic patterns used to establish legitimacy. You won't ever see a bank telling you how they do it, but those "hidden security features" make a significant contribution to the bank's security posture.Their response to having visible security that sucks is to say that they also have a lot of super complicated invisible security which is actually really good? Why am I supposed to believe that? Their invisible security probably sucks even more.
