Now's a good time to review the information you expose in your online life. Declaring what city you live in is fine, but letting everyone know your mailing address is asking for trouble. Review your information and remove anything that can be used against you, according to your own risk threshold. For example, some people have no problem telling everyone where they work, while others think that's an invitation for stalkers or spear-phishing attacks.
Review the privacy settings for each of your social networking sites. Privacy settings change often with little notice -- and when they do, they rarely increase privacy. Think about what you post and how your post. For example, on Facebook, I consider the audience for each post: Public? Friends only? A customized list? The greater the potential privacy invasion a post has, the smaller the post's audience should be.
If your company doesn't offer privacy advice like this as part of employee education, consider adding it. Remember, you're protecting your employees and your business since criminals often steal personal credentials with the intent of cracking into work accounts.
This is such a commonsense post that I've avoided writing it for years. But now that oversharing has resulted in two friends suffering burglaries, I felt it was high time to adress the topic. Sometimes, when you're paranoid, they really are after you!
