Microsoft Beefs Up Office 365 Security
by Pedro Hernandez
The company shows off how it is hardening its cloud-enabled productivity software suite to protect against snoops at TechEd.
Microsoft is signaling to businesses at the TechEd 2014 conference in Houston that their Office 365 data will be subject to even stronger security in the coming months. Office 365, a pillar of Microsoft's new mobile and cloud strategy, has emerged as a big money maker for the company. At last count, Office 365 "is now on a $2.5 billion annual run rate," said Microsoft Office Corporate Vice President John Case recently as he announced a massive OneDrive for Business cloud storage upgrade.
In March, Microsoft finally launched native Office apps for Apple's best-selling iPad tablet. While free to download and use as Office file viewers, the apps require an Office 365 account to unlock their full functionality. Now during TechEd 2014, the company turns its attention to file security. Microsoft is moving "beyond a single encryption key per disk to deliver a unique encryption key per file", announced Rajesh Jha, corporate vice president of Microsoft Office Services and Servers, in a statement. Envisioned as a way to turn SharePoint Online and OneDrive for Business into highly secure content repositories, every file stored in those services "is encrypted with its own key, and subsequent updates to a file are encrypted with their own unique key as well". Jha added that the new, per-file Office 365 encryption technology "will start to deploy to Office 365 business customers beginning in July".
