Option Description Required Username
The username to log in to the hosts you want to scan.
yes
BeyondTrust host
The BeyondTrust IP address or DNS address.
yes
BeyondTrust port
The port on which BeyondTrust listens.
yes
BeyondTrust API user
The API user provided by BeyondTrust.
yes
BeyondTrust API key
The API key provided by BeyondTrust.
yes
Checkout duration
The length of time, in minutes, that you want to keep credentials checked out in BeyondTrust. Configure the Checkout duration to exceed the typical duration of your Tenable Nessus 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 BeyondTrust so that password changes do not disrupt your Tenable Nessus scans. If BeyondTrust changes a password during a scan, the scan fails.
yes
Use SSL
When enabled, Tenable Nessus uses SSL through IIS for secure communications. You must configure SSL through IIS in BeyondTrust before enabling this option.
Caution: If you do not enable this option the traffic that is sent is http and will not be accepted by the Beyond Trust server.
no
Verify SSL certificate
When enabled, Tenable Nessus validates the SSL certificate. You must configure SSL through IIS in BeyondTrust before enabling this option.
no
Use private key
When enabled, Tenable Nessus uses private key-based authentication for SSH connections instead of password authentication. If it fails, the password is requested.
no
Use privilege escalation
When enabled, BeyondTrust uses the configured privilege escalation command. If it returns something, it will use it for the scan.
no
Custom password prompt The password prompt used by the target host. Only use this setting when an interactive SSH session fails due to Tenable Nessus receiving an unrecognized password prompt on the target host's interactive SSH shell. no
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.
no -
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.
