As a government worker, I can state first hand that government IT security is abysmal. Our IT and data security departments aren't qualified professionals, they are everyday workers promoted/transferred from within. Everyone knows that security is terrible, but the people trying to fix it don't have the slightest clue what they are doing. Our password requirements get more ridiculous every year. Almost all of them are retained forever somewhere to make sure you don't re-use. Some of them you even have to select from a pre-determined list (of about 20). I'll try to track down one of the actual password requirement lists later.
