Facebook Can Get You Fired

About eight percent of corporate executives surveyed by Proofpoint say they have terminated

employees for disclosing confidential, protected or simply embarassing information put up on socialnetworking sites such as Facebook or LinkedIn, up from four percent who reported doing so in 2008.

About 17 percent of respondents said they had incidents of that nature this year, compared to 12 percent in 2008.

But email still seems to be a more-common reason for terminations of this sort. About 43 percent of respondents reported they had investigated an email-based leak of confidential or proprietary information in the past 12 months.

Nearly a third of them, 31 percent, terminated an employee for violating email policies in the same period, up from 26 percent in 2008.

About 18 percent of respondents say they had investigated a data loss event from a blog or message board in the past 12 months. About 17 percent disciplined an employee for violating blog or message board policies, while nearly nine percent reported terminating an employee for such a violation, up from a disciplinary rate of 11 percent in 2008 and a termination rate of six percent in 2008.

More respondents also reported investigating video-related exposure events. This year, about 18 percent have had to do so, up from 12 percent in 2008.

About 15 percent of respondents have disciplined an employee for violating multimedia sharing or posting policies in the past 12 months, while eight percent reported terminating an employee for such a violation.

Even short message services like texts and Twitter pose a risk. About 13 percent of respondents

investigated an exposure event involving mobile or Web-based short message services in the past 12 months.

About 38 percent of respondents say they now read or analyze outbound email before it is sent.

As more U.S. companies reported their business was affected by the exposure of sensitive or

embarrassing information (34 percent, up from 23 percent in 2008), an increasing number say they employ staff to read or otherwise analyze the contents of outbound email (38 percent, up from 29 percent in 2008).

In addition, companies are regularly ordered to produce employee email as part of legal actions,

exposing its contents to outside scrutiny. Nearly a quarter (24 percent) of large US companies report that employee email was subpoenaed in the past 12 months.
