Do not scan operational technology devices

info Nessus Plugin ID 109142

Language:

Synopsis

The remote host appears to be a fragile device and will not be scanned.

Description

The remote host appears to be operational technology device. Such devices often react very poorly when scanned. To avoid problems, Nessus will not continue to scan this device unless the scan policy is configured to scan OT devices.

If you would like to safely assess security vulnerabilities on this device, Tenable suggests contacting your account representative to discuss employing Tenable.OT, which is purpose built to address vulnerability management on devices of this type.

Some OT discovery is available in Nessus using a special 'OT Discovery' scan template.

Note: OT devices often have nested interfaces or additional attached devices that may not be accounted for in a traditional scan

Solution

If you are not concerned about such scan behavior, enable the 'Scan Operational Technology devices' setting under 'Fragile Devices' in the 'Host Discovery' section and then re-run the scan.
