In the first installment of a two-part series the need for organizations to address the issue of electronic document security is presented. Electronic document security has come to the forefront of the business and political world with the exposure of classified US military documents in 2010 by the Web site publisher WikiLeaks. Data loss prevention software and appliances stop sensitive e-mails, documents and data from leaving the firewall, based on specified content. Enterprise rights management (ERM) provides embedded file level protections against unauthorized viewing, editing, printing, copying, forwarding or faxing, which travels with the document or data, regardless of media type. The enterprise rights management marketplace is still forming, yet Microsoft is the leader in terms of number of licenses for its Active Directory Rights Management Services (AD RMS) product. The 451 Group's senior analyst, Steve Coplan speculates, RMS' adoption has been held up by some of the enrollment and rule hard-coding issues.
