Basic Settings for Scans
Note: This topic describes Basic settings you can set in scans. For Basic settings in policies, see
The Basic scan settings are used to specify certain organizational and security-related aspects of the scan, including the name of the scan, its targets, whether the scan is scheduled, and who has access to the scan, among other settings.
Configuration items that are required by a particular scan are indicated in the Tenable Nessus interface.
The Basic settings include the follow sections:
The following tables list all available Basic settings by section.

Permissions
Using settings in the Permissions section, you can assign various permissions to groups and individual users. When you assign a permission to a group, that permission applies to all users within the group. The following table describes the permissions that can be assigned.
Tip: Tenable recommends assigning permissions to user groups, rather than individual users, to minimize maintenance as individual users leave or join your organization.
Permission | Description |
---|---|
No Access |
Groups and users set to No Access cannot interact with the scan in any way. When you create a scan, by default no other users or groups have access to it. |
Can View |
Groups and users set to Can View can view the results of the scan. |
Can Control |
Groups and users set to Can Control can launch, pause, and stop a scan, as well as view its results. |
Can Configure |
Groups and users set to Can Configure can modify the configuration of the scan in addition to all other permissions. |
