Difference between SSL and Kerberos authentication?

Question

I am trying to understand what\'s the actual difference between SSL and Kerberos authentications, and why sometimes I have both SSL traffic and Kerberos. Or does Kerberos use S

Answer 1

While Kerberos and SSL are both protocols, Kerberos is an authentication protocol, but SSL is an encryption protocol. Kerberos uses UDP, SSL uses (most of the time) TCP. SSL authentication is usually done by checking the server's and the client's RSA or ECDSA keys embedded in something called X.509 certificates. You're authenticated by your certificate and the corresponding key. With Kerberos, you can be authenticated by your password, or some other way. Windows uses Kerberos for example, when used in domain.

Related note: Recent versions of SSL are called TLS for Transport Layer Security.
