4. Failure To Review Who You've Friended
Most security experts say that it is a good idea to conduct a regular review of all those who you have friended over the years. It may make sense to weed out former girlfriends or boyfriends, reconsider whether your boss or supervisor can view all your posts and reevaluate that friend request you accepted from your first grade pal. Unless you've made a conscious effort to open your life and your posts to the public, keeping the number of people you have friended to a minimum may help reduce the possibility of being socially engineered by a cybercriminal in the future.
