What is NTLMv2 used for?
NTLMv2 is an extension to the NTLM protocol which provides additional security for the user and server, and provides a mechanism for sharing security information.
How does NTLMv2 work? NTLMv2 operates in two stages: NTLMv2 Initialize. This is a request sent from the client to the server. In response to this request, the server sends a challenge.
NTLMv2 Response. This is a response sent from the server to the client. In response to this request, the client sends a response containing the user name and domain.
The NTLMv2 authentication process is illustrated in the following diagram: What is the NTLMv2 security model? NTLMv2 is designed to be used as a successor to NTLM for authentication on Windows 2000/2003 systems. The security model is based on the following assumptions: Authentication requires the following information: domain name. NTLMv2 has two key features which add security to NTLM: The new security tokens (TARGETDOMAIN and TARGETUSER) are opaque. This means that they cannot be decoded.
The new security token contains only enough information to allow the server to perform the requested task. For example, it may contain a Kerberos principal name, but no user name or domain name.
The NTLMv2 security model is based on a series of assumptions: Only the server can generate the new security tokens. The new security tokens cannot be decoded. The new security tokens contain only enough information to perform the requested task. How does NTLMv2 compare with NTLM? NTLMv2 is a superset of NTLM. This means that all of the security functions are the same, except that NTLMv2 has additional security mechanisms.
Security Features. The following list shows the key differences between NTLMv2 and NTLM: The TARGETDOMAIN and TARGETUSER fields are opaque. The TARGETDOMAIN and TARGETUSER fields cannot be decoded. The new security token only contains enough information to perform the requested task.
Is NTLMv2 deprecated?
NTLMv1 was first developed back in 1991 and still supported today in IE 5.
5 and later browser versions like IE6. I could not find NTLMv2 for Internet Explorer in some Microsoft pages, or it may be that it is not supported any. Longer. Do you know what happened to it? Advertisements. You missed something! You can look at a lot of the latest Microsoft support documents where this is still in the supported list. NTLMv2 is not deprecated, though it doesn't work anymore with IE10. -
David W.) As stated in my post above, NTLMv2 was first designed in 1996, is not. Deprecated (I can't think of a single page on a MS site that would state. That it's deprecated) and works with version 5 of IE7. So yes, if it's not supported with ie10, as stated above, the site which. Is "deprecated" because it states v2 rather than v3 has clearly failed in. Telling the truth. The "Deprecated" message should have either pointed to a real page somewhere. On MS who tell what version they're using to say whether it's obsolete or. Not, OR if they're supporting their own product (most likely which is why. They get an email reminder) it should have said you need a recent patch or. Update to the product to support it. Deprecated (I can't think of a single page on a MS site that would state. That it's deprecated) and works with version 5 of IE7.
