Hello

The credential-less discovery uses NMAP to discover the CI.

With credential discovery you must create the credential for each CI connection type (WMI, ssh, snmp, etc).

 

Take a look to this doc: https://docs.servicenow.com/bundle/newyork-it-operations-management/page/product/discovery/concept/n... 

 

Please, mark my answer correct, useful or bookmark if I helped you

Thanks

Ariel

Credential-less Discovery gives some basic information based on Nmap output such as DNS name, MAC address, detecting apps running on a host, host's OS and version.

With Credential Discovery you can discover practically anything about a CI, of course, if you supply local admin (for Windows) / sudo (for Unix) credentials.

Regards,

Alexey

Hi Ram,

Credential less discovery:

If the instance fails to identify a configuration item (CI) because of authentication failure, Discovery or Service Mapping can run selected Network Mapper (Nmap) commands with a MID Server to collect some basic information about the CI without using credentials.

A MID Server administrator can install Nmap on individual MID Servers running on a Windows host. Those MID Servers can then discover some basic information about CIs in your network when normal authentication fails.
 
Credential discovery:
 
Uses credentials from 'discovery_credentials' table based on the credential type to do a deep discovery of the given IP range. This will be enabled automatically when the credential is created and tested.
 
IF my Response is worthy mark as correct/Helpful.
