On Wednesday the Pentagon was hacked which compromised 1500 machines (non-classified systems luckily). Interestingly, the US Defence Secretary Robert Gates, when asked if his email was compromised, said "I don't do e-mail. I'm a low-tech person." Some people have asked, "how does he communicate?" which sounds like a reasonable question.
My guess is that he was telling a little porkie pie because his Cabinet boss appears to be having a few problems relating to email right now so probably best to stay schtum about the subject in case the feral hoardes get the wrong end of the stick.
This aside, you have to ask yourself an important question. If the Pentagon can be hacked, what do you really think about when you hear the Government (on ID cards) or the EU (on data sharing) talk about "safeguards"?
