Inside Facebook's Cyber-Security System

An anonymous reader writes "The Facebook Immunity System (FIS) processes and checks 25 billion actions every day, or 650,000 actions every second. The social networking giant's cybersecurity system was developed over a three-year period to keep the service's users safe from spam and cyberattacks. FIS scans every click on Facebook for patterns that could suggest something malicious is spreading across the social network."

    Numerous pages I've liked incessantly spew spam at me, my mother keeps getting messages from "facebook security" or some variation thereof, asking her to confirm her password.

    I'm not aware of any security system that can prevent external sites from spamming their users. Of course it doesn't help if a company plays fast and loose with your privacy allowing attackers to discover the user base and target them. But as much as I hate Facebook lately, i can't see how you can expect their security system to prevent others from sending your mother email. There are many much more legitimate concerns with Facebook to address, so let's not get into irrationalities and hysterics about things we can't expect them to fix.

    Just saying, if they really want to protect their users, they can do some regular expressions voodoo on their messaging system. If Gmail can recognise phishing and spam, why can't Facebook?

  4. It prevents me from finding Beta Testers by MichaelCrawford · · Score: 4, Informative

    From time to time I would post a link to the Beta Testing announcment for my iOS App. After a while Facebook would not allow me to post the link anymore, claiming that it was abusive.

    A friend of mine who uses Facebook quite a lot had to sign up for a second account because her first account kept getting censored. She was not doing anything the least bit abusive, just using Facebook a lot to keep in touch with her friends.

      You can mark posts from other people as abusive. Perhaps your friend needed to unfriend someone who didn't like what she had to say?
