A recent study from PixAlert, found pornography on one in four PCs despite the use of content filtering technology at the gateway.
PixAlert audited 10,000 PCs on 125 business and public sector networks over the last 9 months. The study found that 25% of the computers contained pornography or “other inappropriate images.” The same audit found that 12.4% of the 12,000 e-mail accounts and 5.4% of 26,000 file server shares scanned were similarly affected.
“With over a third of all images found created in the last 12 months, it is clear that a significant number of employees continue to ignore corporate policies and in some cases are going to extraordinary lengths to bypass protection systems in order to obtain and distribute inappropriate material,” said Andy Churley, a director at PixAlert, in a written statement. “Corporate officers wrongly assume that boundary protection systems stop all digital pornography from entering the organization but, in PixAlert’s experience, almost all corporations will have a significant amount of pornography on their networks.”
The study found that 46.8% of the images showed full nudity or sexual activity and 0.3% of all the images were determined to be illegal. While 35% were downloaded online images, 45.2% of the images detected came from e-mails. The study also found that 35.5% were sent internally.
“While all organisations actively discourage access to inappropriate images at work, our audits show that the reality is that all establishments have a lot of digital pornography residing on their networks that they don’t know about. Companies are particularly concerned when they have visibility of the number of pornographic images being distributed by e-mail internally or sent out to other organisations using a corporate e-mail address.” said Churley.
