London, Oct 28: World's popular social networking site, Facebook has launched Facebook Immunity System (FIS) to keep its users safe from spam and cyber attacks on the the social network.

Besides newly launched FIS, Facebook also has a cyber security system which processes and checks 650,000 actions every second to keep its users protected. FIS is giving better results with just 1% of users reporting issues of spam.

Facebook Immunity System was developed in three years and it is able to handle an estimated 25 billion actions that are made by the social network's 800 million plus users every day.

According to Facebook, the new system has seen spam drop to account for less than 4 per cent of its total messages affecting less than 0.5 percent of its users. The system also has the capacity to take action without checking with a human supervisor.

The immunity system is supported by a team of 30 security experts, each of whom helps search for spam across the network leaving no status update like share or comments unturned.

Moreover, the social network's new immunity system will help to detect 'socialbots', fake users which look and behave like ordinary people on Facebook.
