I am graduating this week with a cs degree and want to go into the field of cyber security. I have been hearing a lot a out security clearances and specifically the polygraph portion. What security clearances are most common in the cyber security private sector? How long are you required to not have done or sold drugs? What kind of questions did they ask you? Polygraphs seem like a pretty stupid measure for security clearance considering they aren’t even admissible as evidence in court.



you only need a clearance if you plan on working for the gov’t or a contractor – there’s a large number of infosec jobs that don’t need a clearance.

regarding your other questions, the answer is: it depends. and while polygraphs are definitely not science, they’re mostly just a way to see if you’re a liar.
