This section provides a brief description of the options available for the Security Risk Scan > Target tab. By default, PortalProtect scans all files on your SharePoint servers, which provides the maximum security. However, scanning every single file requires a lot of time and resources. Therefore, you may wish to consider limiting the number of files PortalProtect includes in its Real-time, Manual, and Scheduled scans.
You can configure PortalProtect to limit scanning to the following files:
All scannable files: scans all content passing through or being stored on the SharePoint environment.
IntelliScan: use Trend Micro IntelliScan to perform an efficient scan.
Specific file types: PortalProtect provides a list of file extensions and true file types from which you can choose for scanning. You can add to this list by typing the file extension in the Specify file extensions configuration field.
