Passwords
Everybody knows that passwords are weak authentication. But sometimes it's all we have. A while back an irate prof. accused me of being inflexible (imagine--an info sec guy inflexible?). The prof. felt he should not have to change his password. He made his argument claiming he didn't have access to any sensitive information. I asked him if he thought his banking information and social security number were sensitive. He agreed that they were. I pointed out that his univ. ID and password gave him access to his banking information and social security number in our ERP (not to mention student records). He came back saying his bank doesn't make him change his password or PIN. What could I say other than telling him I care more about his private information than his bank does?
