# Configure real-time scanning properties

Real-time scanning properties allow control over which users have access to real-time scanning, and how the scan operates within their environment. Perform the following procedure to configure real time scanning properties.

## Before you begin

-   The application scope is set to a scope that is not part of the Scan Engine project. When the scope is set to Scan Engine real-time scanning doesn't activate.
-   The tables that you want to scan have active entries in the sn\_se\_applicable\_table table.
-   The tables that you want to scan aren't listed in the **excluded\_tables** property. on the Real Time Scanning properties tab.
-   The **read\_access** attribute of the sys\_update\_version table is set to true. If it is not, the Scan Engine disables itself.

Role required: Scan Engine Admin \(`sn_se.scan_engine_admin`\) or admin.

## Procedure

1.  Navigate to **All** > **Impact** > **Configuration** > **Scan Engine Properties**.

2.  On the Real Time Scanning tab, select the **Enforce real time validation** checkbox to activate real-time scanning.

3.  In the Real time message visibility drop-down, select who will see real-time scanning results:

    -   All users: All users in Impact can access real-time messages.
    -   Only users with the scan\_engine\_user role: LImited to users with the assigned role to view real-time messages.

    Users designated in **Real Time Message Visibility** must resolve Act and Recommend level findings before they save the form. A Recommend finding stops blocking when an exception is submitted for it, and so does an Act finding that is eligible for an exception. The exception can be a draft, and it doesn't need to be approved. Suggest and Review findings never block a save.

4.  Select whether to **Exclude suggestion finding**, which hides Suggestion level findings from real-time display, showing only Review, Warning, and Error levels.

    The Excluded tables area lists which tables are being excluded from real-time scanning. To add a table to this list, select the field and enter the name. You can't remove default tables from this list.

    **Note:** The tables listed here will be included in scheduled scans but will not display findings in real-time.

5.  Enter a number for the **Maximum Lines for Real-Time Scan**.

    This sets the maximum number of code lines that can be scanned in real-time. Scripts exceeding this limit will not be scanned during editing.


-   If you can't edit the properties, or real-time scanning does not activate after you complete these steps, check your instance for custom ACLs or property overrides.
-   After you change the properties, you might need to log out and log back in for the settings to take effect.
