What is Kerberos??

Kerberos is a protocol for creating authenticated channels. It has long been in use, though I don’t think it’s supposed to have user facing notifications. It’s more of a back-end/implementation thing than something a user would need to think about.

As @casperes1996 says. Your Mac probably connects to an Active Directory domain (but that is not the only use of Kerberos).
there's another thread about this as well.
i have it on both of my macs. since just some of us have this, there must be a common denominator (see gilby101's post above)...

It’s for use that using smart cards. Notification when the card asking for pin etcKerberos is a protocol for creating authenticated channels.

Kerberos is a secure authentication protocol. For a general description see https://en.wikipedia.org/wiki/Kerberos_(protocol). It was developed at MIT and is still actively developed - see: https://web.mit.edu/Kerberos/. It is the default authentication mechanism on Windows (since Windows 2000 and Active Directory).
The Apple document on Kerberos as single sign on extension is here: https://www.apple.com/business/docs/site/Kerberos_Single_Sign_on_Extension_User_Guide.pdf. But kerberos use is a bit wider than this. For macOS, it is involved in screen sharing and, I expect, other places where secure authentication is required.
If you look at your open network ports, you will see port 88 is open for connections by the kdc (key distribution centre) process.
Kerberos has always been installed as part of OS X and macOS. Don't attempt to disable.
