> And Danny, apart from your suggestions on full disk encryption and other points which are well taken, we also very much understand the importance of stressing concepts, giving people of sense of threats and options, and underscoring the importance of staying informed about changes including vulnerabilities and updates. In fact, we are avoiding the firehouse training approach, and instead developing four-week classes, in order to make sure that everyone gets concepts instead of just learning tools. The idea is to give people a foundation so they can then take responsibility and make informed choices for their own digital safety. Or so they can trust their own instincts, as I have heard you say.
