Security enhancements

What's new home

Macro Security   Microsoft Office Access 2003 allows you to help protect against potentially unsafe Visual Basic for Applications (VBA) code by setting the macro security level. You can set the security level so that you are prompted every time that you open a database containing VBA code, or you can automatically block databases that are from unknown sources.

Additionally, Access uses Microsoft Authenticode technology to enable you to digitally sign (digital signature: An electronic, encryption-based, secure stamp of authentication on a macro or document. This signature confirms that the macro or document originated from the signer and has not been altered.) a VBA project by using a digital certificate (digital certificate: Attachment for a file, macro project, or e-mail message that vouches for authenticity, provides secure encryption, or supplies a verifiable signature. To digitally sign macro projects, you must install a digital certificate.). The certificate used to create this signature confirms that the macro originated from the signer, and the signature confirms that it has not been altered. When you set the macro security level, you can run macros based on whether they are digitally signed by a developer on your list of trusted sources.

Block Potentially Unsafe Functions   Access utilizes the Microsoft Jet Expression Service enhanced sandbox mode to block potentially unsafe functions from being used in expressions.
