Facebook Learns The Downside To Making Logins Easy

Mobile communications in general—and M-Commerce in particular—are predicated on promises of speed and convenience. But that supposition tends to run counter to robust security, and therein lies the inherent conflict between mobile and security. Meanwhile, Facebook stands as the leader of social networks, and those networks also are based on convenience.

Our tale today involves a recent problem that Facebook experienced, where registered users logged in to the social site and saw the personal contacts and messages of other users rather than their own. But the glitch only happened when users were coming in through AT&T. That glitch is the topic of our weekly security column on McAfee's blog.
