    Option Default Value

    Arcon host

    (Required) The Arcon IP address or DNS address.

    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 Tenable Nessus Manager uses to access Arcon.

    Password Engine URL

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

    Username (Required) The username to log in to the hosts you want to scan.
    Arcon Target Type (Optional) The name of the target type. . Depending on the Arcon PAM version you are using and the system type the SSH credential has been created with, this is set to linux by default. Refer to the Arcon PAM Specifications document (provided by Arcon) for target type/system type mapping for the correct target type value.
    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 Vulnerability Management 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 Vulnerability Management scans. If Arcon changes a password during a scan, the scan fails.

    Use SSL When enabled, Tenable Nessus Manager uses SSL through IIS for secure communications. You must configure SSL through IIS in Arcon before enabling this option.
    Verify SSL When enabled, Tenable Nessus Manager validates the SSL certificate. You must configure SSL through IIS in Arcon before enabling this option.
    Targets to Prioritize Credentials

    Specify IPs or CIDR blocks on which this credential is attempted before any other credential. To specify multiple IPs or CIDR blocks, use a comma or space-separated list.

    Using this setting can decrease scan times by prioritizing a credential that you know works against your selected targets. For example, if your scan specifies 100 credentials, and the successful credential is the 59th credential out of 100, the first 58 credentials have to fail before the 59th credential succeeds. If you use Targets To Prioritize Credentials, you configure the scan to use the successful credential first, which allows the scan to access the target faster.

  14. Do one of the following:

    • If you want to save without launching the scan, click Save.

    • If you want to save and launch the scan immediately, click Save & Launch.

      Note: If you scheduled the scan to run at a later time, the Save & Launch option is not available.
