Information rights management
June 25, 2014
Windows Phone device administrators desiring to prevent leaks of intellectual property should consider utilizing the Information Rights Management (IRM) functionality in Windows Phone 8.1. When IRM is employed, the data in rights-protected documents or email messages is encrypted, so that it can only be viewed by authorized users. IRM can also be used to limit other rights to a document or message, such as limiting access to read-only, preventing content in the document or message from being copied, or preventing the document or message from being printed.
IRM relies on Windows Rights Management Services (Windows RMS), a Windows Server-based technology that IT administrators can configure to create the issuance license and perform the encryption of rights-protected documents. In addition, Windows RMS can be applied to email so that messages can circulate in a protected environment, but not be forwarded outside the organization. RMS can also be applied to documents that are attached to email or stored on Microsoft SharePoint servers, limiting distribution and editing capabilities and helping to prevent information from being leaked to unauthorized personnel.
IRM can be configured by using the EAS policy Allow IRM over EAS. For more information about Information Rights Management, see Information Rights Management in the TechNet Exchange Server content library.
