Computer security company Kaspersky Lab has revealed that almost three-quarters of companies worldwide (72%) block access to social networking sites.
The Moscow-based firm said that most companies have strict rules when it comes to using Facebook and similar sites at work.The company said that many organisations are concerned about the potential negative impact social networking may have on their business and they believe employees will waste time accessing Facebook, Twitter and other social networking sites, instead of focusing on work.
The companies are also concerned about the security aspects of social networking, added Kaspersky.
The fears of the companies are not unfounded, said Kaspersky. It said the volume of malware spreading through social networks has increased, and is increasing, steadily. The other potential security problem is less obvious: social networks are filled with masses of personal data. "And this data can be used by cybercriminals, not only to profile individuals, but also organisations," said Kaspersky.
