OK, folks. There’s general phobic concern about Facebook privacy on pretty much every level, lately. My own institution, after allowing single-sign on into Facebook from the university portal for over two years, recently pulled this feature due to concerns about privacy. I don’t want to paint my advisee or collegial Facebook friends with the same brush, so I assume no level security proficiency, nor lack thereof. I simply wanted to share a pretty good resource to which I’ve subscribed. This site does the heavy lifting for you and has some pretty good Facebook security tips to share.
