Integrated Windows Authentication itself is not a standard or an authentication protocol. When IWA is selected as an option of a program (e.g. within the Directory Security tab of the IIS site properties dialog) [ 7 ] this implies that underlying security mechanisms should be used in a preferential order.
Security Support Provider Interface (SSPI) is a component of Windows API that performs security-related operations such as authentication.. SSPI functions as a common interface to several Security Support Providers (SSPs): [1] A Security Support Provider is a dynamic-link library (DLL) that makes one or more security packages available to apps.
SPNEGO's most visible use is in Microsoft's "HTTP Negotiate" authentication extension. It was first implemented in Internet Explorer 5.01 and IIS 5.0 and provided single sign-on capability later marketed as Integrated Windows Authentication. The negotiable sub-mechanisms included NTLM and Kerberos, both used in Active Directory. The HTTP ...
In a Windows network, NT (New Technology) LAN Manager (NTLM) is a suite of Microsoft security protocols intended to provide authentication, integrity, and confidentiality to users. [1] [2] [3] NTLM is the successor to the authentication protocol in Microsoft LAN Manager (LANMAN), an older Microsoft product.
Password Authentication Protocol is one of the oldest authentication protocols. Authentication is initialized by the client sending a packet with credentials (username and password) at the beginning of the connection, with the client repeating the authentication request until acknowledgement is received. [6]
Some strong authentication protocols for web-based applications that are occasionally used include: Public key authentication (usually implemented with a HTTPS / SSL client certificate) using a client certificate. Kerberos or SPNEGO authentication, employed for example by Microsoft IIS running configured for Integrated Windows Authentication (IWA).

In computing, the Challenge-Handshake Authentication Protocol (CHAP) is an authentication protocol originally used by Point-to-Point Protocol (PPP) to validate users. CHAP is also carried in other authentication protocols such as RADIUS and Diameter. Almost all network operating systems support PPP with CHAP, as do most network access servers.
