Why would the app Kerberos be on my system?

Hi

On my mid-2015 MB Pro, I noticed the app Kerberos when looking at Sys Prefs> Notifications & Focus. It is a network authentication protocol and designed to provide strong authentication for client/server applications by using secret-key cryptography.

It's not in my lists of applications. It's in many commercial products.

Any reason to be suspicious? How would I delete it if it's not in the App folder?

Can I discover which product it serves?
