IV  Windows NT Security
(Page 1 of 2)

Several pieces of NT comprise the NT security model. For the NETWORK+ test, be familiar with the following.

Login

Net logon and Win logon process the user requests for access. Winlogon handles the local access, with the remote or network access is handled by the Net logon. Net logon is not a visible process, whereas the Win logon is.

LSA

LSA (Local Security Authority) is responsible for checking permission to access the local (interactive) system. This program is responsible for creating access tokens for local security and interactive user authentication. Besides that it manages the audit policies and logs for security.

SAM

SAM (Security Accounts Manager) maintains the user accounts database. This database holds the information for all users and group (global and local) along with the access level they have in the NOS.

The LSA uses the validation service that is provided by the SAM database.

SAM became NTDS with Windows 2000/.Net

In later versions of Microsoft Window, and possibly the NETWORK+ test, the SAM is called the NTDS (NT Directory Services).

(Don’t confuse this with the Novell Netware NDS feature!)
