Companies afraid of iPhones and Twitter -

A report from Forrester Research suggests that businesses in North America and Europe will spend significantly more on IT security this year.

Over 2,000 companies Forrester survey showed that 42 percent of enterprises will increase their IT security spend by five percent or more this year, while 37 percent of small to medium sized businesses will do the same.

And it's not cloud computing that's scaring the corporations - they're worried about the proliferation of smartphones and Web 2.0 technologies in the workplace. Nearly half of the large companies surveyed considered smartphones to be a security threat, and 38 percent worried about Web 2.0.

The use of iPods, smartphones, Facebook, Twitter and SharePoint sites are also a concern for the companies, as too are the use of cloud computing services by application developers.

Jonathan Penn, a Forrester analyst, said: "In general, this follows the broader trend of IT losing centralised control of technology adoption, deployment and use."
