We've been hit with quite a few IT doozies thus far this year. I'm sure there've been some furrowed brows, exasperated sighs, and maybe even a few tears. You all clearly do more for your end users than they'll ever know. That's why you're like the Dark Knight.
Anyway, I want to know how you'd rank the list of IT security threats and vulnerabilities that have sprung up in 2014 thus far. Heartbleed still giving you the nervous sweats? Internet Explorer flashbacks giving you chills?
Feel free to share your top 5!
