Why do we need Kerberos?
Why Kerberos is needed. Kerberos has two purposes: security and authentication. On most computer systems, a password is used to prove a user’s identity; on a distributed network system, like Athena, this password must be transmitted over the network, from the workstation being used, to any other machines containing files or programs the user wants access to.
Is Kerberos a product or a standard?
In the Unix community, Kerberos is a network-authentication service developed at MIT that has become a standard for Unix. Microsoft, up to Windows NT Server 4, used a proprietary authentication mechanism called NT LAN manager challenge/response (NTLM/CR).
