to restrict such behaviors given the possibility to write applications use the web services directly to obtain licenses to decrypt the content. In addition, using this same technique, a user that has been granted rights to view a protected document can manipulate the content of the document without leaving traces of the manipulation. Since Azure RMS is not a non-repudiation solution and, unlike document signing solutions, does not claim to provide anti-tampering capabilities, and since the changes can only be made by users that are granted rights to the document, Microsoft does not consider the later issue to be an actual attack against the claimed capabilities of RMS. The researchers provide a proof of concept tool, to allow evaluation of the results, via GitHub. Software support RMS is natively supported by the following products: Microsoft Office 2003 and later: Word, Excel, PowerPoint, Outlook, InfoPath Microsoft Office for Mac 2011 and later: Word, Excel, PowerPoint, Outlook SharePoint 2007 and later Exchange Server 2007 and later XML Paper Specification (XPS) Third-party solutions, such as those from Secure Islands (acquired by Microsoft), GigaTrust and Liquid Machines (acquired by Check Point) can add RMS support to the following: SharePoint 2003 Microsoft Visio Microsoft Project Adobe Acrobat Internet Explorer IIS 6.0 See also Microsoft Servers References External links Windows Rights Management Services RMS Client downloads RMS SDK for RMS-enabling applications Troubleshooting Windows Rights Management Services (RMS) - One Root Certification Server Warning Active Directory Rights Management - In Summary Active Directory Rights Management Services SDK 2.0 Active Directory Rights Management Services - TechNet Active Directory Rights Management Services - MSDN Secure Islands IQProtector - Information Protection and Control using Microsoft RMS Windows RMS Technical Overview Microsoft server technology Microsoft Windows security technology Windows components Digital rights management
