Is Kerberos secure?
Kerberos is more secure than other authentication methods because it does not send plain text pass- words over the network and instead uses encrypted tickets.
How is Kerberos used today and why it is important?
Kerberos is a computer network security protocol that authenticates service requests between two or more trusted hosts across an untrusted network, like the internet.
