Microsoft XML Core Services (MSXML) 5.0 for Microsoft Office - XML Developer's Guide

XML and Security

Making XML documents secure requires secure infrastructures for transferring and processing those documents. On the client side, security zones in Microsoft® Internet Explorer 5.0 and later can help you manage the flow of XML information. On the server side, you must create applications that manage security, not just for XML documents, but for all the resources, including external entities, document type definitions (DTDs), and style sheets, referenced by those XML documents.
