NTLM: NTLM is the authentication protocol used on networks that include systems running the Windows operating system and on stand-alone systems. NTLM credentials are based on data obtained during the interactive logon process and consist of a domain name, a user name, and a one-way hash of the users password.
Kerberos: Kerberos is a client-server authentication protocol that enables mutual authentication – both the user and the server verify each other’s identity – over non-secure network connections. The protocol is resistant to eavesdropping and replay attacks, and requires a trusted third party.
The Kerberos protocol uses a symmetric key derived from the user password to securely exchange a session key for the client and server to use.
