Highlights

When a user logs on to a computer, a series of steps begins that makes up the authentication process. Authentication validates user identity and defines resources that a user can access. Windows operating systems use NTLM or the Kerberos V5 authentication protocol. Authentication is mostly automatic, but understanding the protocols, policies, and other elements involved can help you configure and manage authentication and strengthen security.
