    Option Default Value

    Arcon host

    Note: If your Arcon installation is in a subdirectory, you must include the subdirectory path. For example, type IP address or hostname/subdirectory path.

    Arcon port

    The port on which Arcon listens.

    API User

    (Required) The API user provided by Arcon.

    API Key

    (Required) The API key provided by Arcon.

    Authentication URL The URL Nessus Manager uses to access Arcon.

    Password Engine URL

    The URL Nessus Manager uses to access the passwords in Arcon.

    Username (Required) The username to log in to the hosts you want to scan.
    Checkout Duration

    (Required) The length of time, in hours, that you want to keep credentials checked out in Arcon.

    Configure the Checkout Duration to exceed the typical duration of your Tenable.io scans. If a password from a previous scan is still checked out when a new scan begins, the new scan fails.

    Note: Configure the password change interval in Arcon so that password changes do not disrupt your Tenable.io scans. If Arcon changes a password during a scan, the scan fails.

    Use SSL If enabled, Nessus Manager uses SSL through IIS for secure communications. You must configure SSL through IIS in Arcon before enabling this option.
    Verify SSL If enabled, Nessus Manager validates the SSL certificate. You must configure SSL through IIS in Arcon before enabling this option.
  1. Click Save.

What to do next:

To verify the integration is working:

  1. On the My Scans page, click the Launch button to initiate an on-demand scan.

  2. Once the scan completes, select the completed scan and look for Plugin ID 97993 and the corresponding message - It was possible to log into the remote host via SSH using 'password' authentication. This result validates that authentication was successful.
