Computer and user

The access token is a representation of the user account and contains the following elements.The Resource Kit is also located on the Windows 2000 Server and Advanced Server CDs as part of Support Tools.A DACL or SACL consists of a list of Access Control Entries (ACEs), where each ACE lists the permissions granted or denied to the users, groups, or computers listed in the DACL or SACL.The entire set of permission entries in a security descriptor is known as a permission set.Computer science is a discipline that spans theory and practice. practically everyone is a computer user, and many people are even computer programmers.

For Active Directory objects, Windows 2000 also supports per-property permissions.This article describes how to manage stored user names and passwords on a computer that is not a member of a domain.You must create a name mapping between the external user certificate and the Active Directory account you have created for authenticated access.When a Windows NT primary domain controller (PDC) is upgraded to Windows 2000 Active Directory, Windows NT local groups become Windows 2000 local groups and Windows NT global groups become Windows 2000 global groups.The Guest account is disabled and you must enable it explicitly if you want to allow unrestricted access to the computer.Groups are Active Directory (or local computer) objects that can contain users, contacts, computers, and other groups.

Both types of group—security and distribution—can have one of three scopes (four when you include local groups, which exist in Windows 2000 to provide backward compatibility with Windows NT groups).

Privileges (associated with each SID) granted to the user or to groups to which the user belongs.Experience shows that using the approach described below will help you achieve maximum flexibility, scalability, and ease of administration when managing security groups.

Local groups can have members from anywhere in the forest, from trusted domains in other forests, and from trusted down-level domains.If a password is used to log on to a Windows 2000 computer using a domain account in a Windows 2000 domain, Windows 2000 uses Kerberos version 5 (V5) for authentication.The exact authentication method (primarily, which digital certificate format will be used) depends on the negotiated cipher suite.For example, users who are members of the Enterprise Administrators group are, by default, granted permission to log on at any domain controller in the Active Directory forest.

The third subsection describes authenticating external users.Option 2: From there, you can use what we call CWA Chaining with Cisco ISE, which is the ability to use the 802.1X credential AND a Web Authentication credential that was typed by an interactive user.When a domain is converted to native mode, local groups become domain local groups.You must establish a user account (for use by one or more external users).The Administrator account is the most powerful account because it is a member of the Administrators group by default.Groups with global scope help you manage directory objects that require daily maintenance, such as user and computer accounts.You can use Group Policy to configure security options, manage applications, manage desktop appearance, assign scripts, and redirect folders from local computers to network locations.

There is an option to keep the machine state for the network authentication, but there is no option in native Windows for the user state to extend beyond logoff, or to validate both the machine and the user credentials.Both mixed-mode and native-mode domains can include Windows NT 4.0 member servers and Windows NT and Windows 9. x clients.That is, a service can be configured to log on (authenticate) as a user account, and it is then granted access to specific network resources through that user account.Together, user authentication and user authorization provide a strong, easy to administer security system for your network.

in a GPO, which takes precedence, user or computer use security groups to manage user, group, and computer access to shared resources and to filter Group Policy settings.Important: In the following discussion of group scope, remember that you assign permissions only to security groups (not to distribution groups).

Objects with SIDs can log on to the network and can then access domain resources.Access control permissions (such as Read, Write, Full Control, or No Access) are attached to Windows 2000 objects.

This is important to note, because each user will have their own credential store on the same computer.

In my own weird way, Figure 1 is meant to illustrate a Windows Computer connecting to an 802.1X enabled network.

For example, you might use universal groups to build groups that perform a common function across an enterprise.A powerful multi-user computer capable of supporting many hundreds or thousands of users simultaneously.Cisco can do EAP-Chaining today with EAP-FASTv2, but that is not a standard, TEAP is.
