Understanding Built-In Office Security Features

Administrating security features of Microsoft Office 2003 can be difficult due to the myriad of possible security issues businesses encounter every day. Understanding the built-in security features of Office can help make identifying the necessary configuration changes for a specific business security requirement easier to accomplish. The following content presents information about the macro security model of Visual Basic for Applications for Office and the Microsoft Office antivirus application programming interface (API).

Understanding macro security

Macro security depends on Microsoft Authenticode® technology. Authenticode uses a digital signature as a means of identifying a data file and executable code attached to an Office item—such as a document, workbook, presentation, or e-mail message—so it can be traced back to the originator of the work. The validation of this signature requires the legitimate authentication of the author who signed the macro, and the authentication of the certificate of trust created for the author and included with the signature. Attaching a signature to a file, executable, Microsoft ActiveX® control, dynamic-link library (DLL), or other data file requires obtaining a certificate from a certificate authority.
