To add an active scan:

  1. Log in to Tenable Security Center via the user interface.

  2. Click Scans > Active Scans.

    The Active Scans page appears.

  3. Click Add.

    The Add Active Scan page appears.

  4. Click General.

  5. Type a Name for the scan.

  6. (Optional) Type a Description for the scan.

  7. Select a Policy for the scan.

  8. (Optional) If you want to schedule the scan to run automatically, select a Schedule for the scan.

  9. Click Settings.

    The Settings tab appears.

  10. If prompted, select a preconfigured Scan Zone for the scan.

  11. Select an Import Repository for the scan.

  12. Select a Scan Timeout Action for the scan.

  13. Select a Rollover Schedule for the scan.

    4. Click the check mark to save your selection.

  19. (Optional) If you want to configure multiple credentials for the active scan, repeat step 19.

    Note: When running an active scan, Tenable Security Center attempts authentication using the newest credentials added by an Administrator user. If the newest Administrator-added credentials do not match, Tenable Security Center attempts authentication with older Administrator-added credentials.

    Then, if no Administrator-added credentials match, Tenable Security Center attempts to authenticate using the newest credentials added by an organizational user. If the newest organizational user-added credentials do not match, Tenable Security Center attempts authentication with older organizational user-added credentials.

    If no credentials match, the scan runs without credentialed access.

    1. Click Post Scan.

      The Post Scan tab appears.
