McAfee, Inc. research reveals only one in five businesses in EMEA block access to social networking sites

Social networking sites sit alongside other technologies that IT professionals perceive as threats but do not or cannot limit access to; such as instant messenger and web-based email, suggesting IT departments are leaving themselves open to security risks due to more important business priorities.

"IT decision makers often have the difficult job of making a choice between what they know are serious security threats and other business priorities such as productivity and employee morale. This is where we see usage policies coming into play as a way to bridge the gap between what IT departments would like to block in an ideal world and what is functionally realistic,"

said Patrick Hayati, Regional Director, McAfee Middle East.

Music downloads and Internet dating sites are the only sites featured on both the blocked and threat lists. The most commonly blocked technologies are Internet dating (36%), music downloads (36%), online music communities (24%), video content (24%) and online radio (23%).
However, the technologies perceived to be most dangerous are music downloads (58%), Internet dating (56%), instant messenger (53%), social networking sites (48%) and web-based email (46%). These findings are indicative of the ongoing balancing act that IT decision makers face on a daily basis.

The reasons why

The driving reason for most IT professionals to be concerned about these technologies is that they believe them to spread viruses (57%) and encourage spam (54%). Ultimately, those polled believe this could have a significant financial risk, citing downtime and fraud as their top concerns should IT security be breached.
McAfee advises IT professionals to assess the dangers and employ usage policies combined with security software to limit the business' exposure to threats whilst still delivering technologies that meet the business' productivity needs.
