Data encryption
Encryption has gained a lot of attention since the Snowden leaks. Major service providers like Microsoft, Yahoo and Google set the tone by adding end-to-end encryption of data they host and manage for customers.
For instance, Google Cloud Storage now automatically encrypts all new data before it’s written to disk. Such server-side encryption will soon be available for older data stored in Google clouds.
Since the NSA programs were disclosed, Microsoft has announced that it plans to ramp up encryption support for various services, including Outlook.com, Office 365, SkyDrive and Windows Azure.
