One of the biggest hacking targets in cloud computing is Google.
The search giant and provider of online services was hit by an attack from China in 2009 that exposed the risk to data under Google's control. The attack appeared to focus on the Gmail accounts of human rights activists, not data that the Silicon Valley company was storing for business clients.
However, Google is experiencing more attacks against both its consumer and corporate data, according to Eran Feigenbaum, director of security for Google Apps. The company now employs 300 information-security professionals dedicated to protecting the data. The Gmail incident accelerated Google's introduction of new security measures, such as two-factor authentication, or using your cell phone to log into your account.
