How does MIT Kerberos work?

Under Kerberos, a client (generally either a user or a service) sends a request for a ticket to the Key Distribution Center (KDC). The KDC creates a ticket-granting ticket (TGT) for the client, encrypts it using the client’s password as the key, and sends the encrypted TGT back to the client.

Which are the two versions for Kerberos?

Difference between Kerberos Version 4 and Kerberos Version 5 :

• Kerberos version 4 was launched in late 1980s.
• It provides ticket support.
• Kerberos version 4 works on the Receiver-makes-Right encoding system.
• It does not support transitive cross-realm authentication.

What is Active Directory Kerberos?

Does Active Directory still use Kerberos?

Active Directory uses Kerberos version 5 as authentication protocol in order to provide authentication between server and client. Kerberos protocol is built to protect authentication between server and client in an open network where other systems also connected.

Is there anything better than Kerberos?

Kerberos. For encryption, IPSec is a better choice because the SQL Server 2000 client and server Net-Libraries don’t offer a way to enable Kerberos encryption. IPSec can encrypt the entire network packet and protect it from tampering.
