Security is a paramount concern in cloud storage today, so woe betide the platform provider even perceived as being the least bit cavalier about security.

Box.net is covering all the bases when it comes to the security of its platform as the cloud storage provider recently announced a new set of tools and access controls for the enterprise. Company officials also announced a product integration with Intel (News - Alert) to deliver what they characterize as “additional protections for users and increased admin capabilities for IT managers.”

Not that Box.net was any slouch when it came to security before the recent announcements; you don’t get to provide storage for 77 percent of the Fortune 500, and get 100,000 businesses using your service if you slack off on security. The company’s just ensuring that it remains state of the art.

In general, with the announcements, Box.net is making controls even more granular. When users share any links on the storage platform, company officials explain, “users can limit who can view a file or folder to only users within a company domain or to collaborators within a specific folder. Users can structure this so that these security controls only extend to individual files or to entire folders of content.”

Users can also track logins from mobile devices, desktops via Box Sync as well as via custom apps using Box APIs.

The integration with Intel means integrations to simplify how IT administrators manage user permissions, company officials explained, as well as group access through Single Sign-On (SSO) and authentication.

Getting in the swing of the Christmas spirit,  Sony Ericsson (News - Alert) recently announced details of a new promotion that will give every Xperia owner 50GB of free file sharing and storage in partnership with Box.net.

By simply logging into their Box.net account through the Box for Android (News - Alert) application in the Android Marketplace, Xperia owners globally will be able to enjoy free cloud storage and file sharing for life.

The Box.net promotion began on Dec. 15 and runs through Dec. 31, and is available to all consumers worldwide who own any Xperia smartphone including and released after Xperia X10.
