James-NSC writes "My employer is changing its policy towards employee use of social networks. I've been asked to give a 40 minute presentation to the entire company (attendance is mandatory) on the security and privacy concerns pertaining to social networking. While I was putting it together, I ended up with some miscellaneous information that pertains to security/privacy in general. Ex: the emerging ATM skimming (mainly for our European employees), a reminder that email is not private, malware/drive-by in popular search results, things of that nature. Since these don't really fall into the slated topic, I've ended up with a section titled "While I have you...". I'm going to have the attention of every employee and with attendance being mandatory, I thought it would be a great opportunity to give advice on security/privacy issues as a whole and not just those pertaining to social networks. As it's an opportunity that one seldom gets, I'd hate to not utilize it to its full potential. If you had the attention of an entire company with employees in the US, UK, Asia and Australia, what advice would you give?"
