NTLM. 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.
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.
NTLMSSP ( NT LAN Manager (NTLM) Security Support Provider) is a binary messaging protocol used by the Microsoft Security Support Provider Interface (SSPI) to facilitate NTLM challenge-response authentication and to negotiate integrity and confidentiality options. NTLMSSP is used wherever SSPI authentication is used including Server Message ...
An access token is an object encapsulating the security identity of a process or thread. [2] A token is used to make security decisions and to store tamper-proof information about some system entity. While a token is generally used to represent only security information, it is capable of holding additional free-form data that can be attached ...
Integrated Windows Authentication. Integrated Windows Authentication ( IWA) [1] is a term associated with Microsoft products that refers to the SPNEGO, Kerberos, and NTLMSSP authentication protocols with respect to SSPI functionality introduced with Microsoft Windows 2000 and included with later Windows NT -based operating systems.
e. Digest access authentication is one of the agreed-upon methods a web server can use to negotiate credentials, such as username or password, with a user's web browser. This can be used to confirm the identity of a user before sending sensitive information, such as online banking transaction history.
MS-CHAP is used as one authentication option in Microsoft's implementation of the PPTP protocol for virtual private networks. It is also used as an authentication option with RADIUS [ 2] servers which are used with IEEE 802.1X (e.g., WiFi security using the WPA-Enterprise protocol). It is further used as the main authentication option of the ...
Two-factor authentication ( 2FA) is a method of adding additional security to your account. The first "factor" is your usual password that is standard for any account. The second "factor" is a verification code retrieved from an app on a mobile device or computer. 2FA is conceptually similar to a security token device that banks in some ...
