Are most people doing two-factor authentication right?

Needless to say we're big proponents of two-factor authentication around here. We also have a pretty broad spectrum of customers from large service providers pushing two-factor authentication out to customer to small businesses doing security for the first time thanks/due to PCI requirements. A lot of infosec rock stars talk about how PCI should be a floor and without disagreeing, we first hand see companies reaching that floor, called by some the 'information security poverty line' and know that it is a big improvement.

UGa breach, "Secret Questions" and blaming the user

The University of Georgia announced an intrusion and a breach of 8,500 personnel records including full names, social security numbers and other data.  The attackers apparently reset the passwords of two IT workers who had access to personnel records using the password reset mechanism - they guessed or discovered the answer to secret questions.  "Secret questions" are an incredibly weak authentication mechanism.  We will likely see many more breaches like this.

Updated OpenVPN & Two-factor authentication tutorial

We recently updated the tutorial on how to add two-factor authentication to OpenVPN AS over on HowToForge.   It's quite easy.

For a long time I have been meaning to pull together some of the top tips when setting up two-factor authentication. I expect this will be a moving target.

I know something that isn't two-factor authentication

William Edwards wrote a post entitled "I know someone whose 2-factor phone authentication was hacked…" about a friend whose bank account was drained by fraudsters. His bank relied on a dial-back system. The attackers social-engineered BT to re-route the phone calls. This attack is eerily similar to the recent attack on Cloudflare, which started with an attack on an AT&T account.
