Windows Credentials

Tenable Security Center has vulnerability checks that can use a Microsoft Windows account to find local information from a remote Windows host. For example, using credentials enables Tenable Security Center to determine if important security patches have been applied.

Tip: Using a non-administrator account will greatly affect the quality of the scan results. Tenable recommends you create a Nessus user account with local administrative privileges specifically for scheduled scanning.

Configure the following options for Windows credentials, including options specific for your authentication method:

General Options Description

Name

 (Required) A name for the credential.
Description A description for the credential.

Tag

 A tag for the credential. For more information, see Tags.
