E-mail Causes Most Enterprise Data Loss

the rise, finds Proofpoint study.

Although e-mail continues to be the primary source of data-loss risk at
enterprises, the number of data-loss events associated with social media
tools -- and related disciplinary actions -- continues to grow, a new
study found.

In fact, 35% of large enterprises have investigated a leak of
confidential, sensitive, or proprietary data via e-mail in the past year,
according to a study of 261 large businesses by Osterman Research for
Proofpoint. And 25% of the U.S. companies surveyed had looked into the
exposure of such information via a blog or message board, compared with
18% in 2009, the study found.

One-fifth of businesses looked into similar postings on a social
networking site such as Facebook or LinkedIn, according to the report.
Last year, 17% of enterprises took this step, the study found. In
addition, 18% of U.S. enterprises investigated postings on media-sharing
sites such as YouTube and Vimeo, while 17% looked into data exposure on
SMS text or web-based short message systems such as Twitter, according to
