Guest account windows 2000

If this policy is not contained in a distributed GPO, this policy can be configured on the local device by using the Local Security Policy snap-in. This section describes how an attacker might exploit a feature or its configuration, how to implement the countermeasure, and the possible negative consequences of countermeasure implementation. The guest account exists in all Windows server and client operating system versions beginning with Windows Server and Windows XP Professional.

Because the account name is well known, it provides a vector for a malicious user to get access to network resources and attempt to elevate privileges or install software that could be used for a later attack on your system. Specify a new name in the Accounts: Rename guest account setting to rename the Guest account.

If you rename this account, it is slightly more difficult for unauthorized persons to guess this privileged user name and password combination. For later operating systems, the policy is enabled with Guest as the default.

It is mainly for guest who just one temporary use your PC as guest and instead of giving full administrator access which might result installing unwanted software or making unwanted change in your system, you could just enable guest account and have other people use it.

How satisfied are you with this reply? Thanks for your feedback, it helps us improve the site. In reply to Reza Ameri's post on November 1, Far better to create a Standard User account and call it "Visitor" or some such. Locutus deBorg. Using the Guest account in a home use environment is just fine. Use Table to determine the availability of the various built-in groups.

Each of these groups is discussed later in the chapter. Predefined groups are installed with Active Directory domains. Use these groups to assign additional permissions to users, computers, and other groups. Predefined groups include domain local, global, and universal groups. The availability of a specific built-in group depends on the domain configuration.

Use Table to determine the availability of the various predefined groups. Key predefined groups are discussed later in this chapter.

Note: The group scope for Enterprise Admins and Schema Admins can be either universal or global, depending on the operations mode. In mixed mode, these are global groups. In native mode, these are universal groups. In Windows NT implicit groups were assigned implicitly during logon and were based on how a user accessed a network resource. For example, if a user accessed a resource through interactive logon, the user was automatically a member of the implicit group called Interactive.

In Windows , the object-based approach to the directory structure changes the original rules for implicit groups. While you still can't view the membership of special identities, you can grant membership in implicit groups to users, groups, and computers. To reflect the new role, implicit groups are also referred to as special identities. A special identity is a group whose membership can be set implicitly, such as during logon, or explicitly through security access permissions.

As with other default groups, the availability of a specific implicit group depends on the current configuration. Use Table to determine the availability of the various implicit groups.

Implicit groups are discussed later in this chapter. When you set up a user account, you can grant the user specific capabilities. You generally assign these capabilities by making the user a member of one or more groups, thus giving the user the capabilities of these groups.

You then assign additional capabilities by making a user a member of the appropriate groups. You withdraw capabilities by removing group membership.

In Windows , you can assign various types of capabilities to an account. These capabilities include. Privileges A type of user right that grants permissions to perform specific administrative tasks.

You can assign privileges to both user and group accounts. An example of a privilege is the ability to shut down the system. Logon rights A type of user right that grants logon permissions. You can assign logon rights to both user and group accounts. An example of a logon right is the ability to log on locally. Built-in capabilities A type of user right that is assigned to groups and includes the automatic capabilities of the group. Built-in capabilities are predefined and unchangeable, but they can be delegated to users with permission to manage objects, organizational units, or other containers.

An example of a built-in capability is the ability to create, delete, and manage user accounts. This capability is assigned to administrators and account Operators. Thus, if a user is a member of the Administrators group, the user can create, delete, and manage user accounts. Access permissions A type of user right that defines the operations that can be performed on network resources.

You can assign access permissions to users, computers, and groups. An example of an access permission is the ability to create a file in a directory. Access permissions are discussed in Chapter As an administrator, you'll be dealing with account capabilities every day. To help track built-in capabilities, refer to the sections that follow. Keep in mind that while you can't change the built-in capabilities of a group, you can change the default rights of a group.

For example, an administrator could revoke network access to a computer by removing a group's right to access the computer from the network. A privilege is a type of user right that grants permissions to perform a specific administrative task.

You assign privileges through group policies, which can be applied to individual computers, organizational units, and domains. Although you can assign privileges to both users and groups, you'll usually want to assign privileges to groups. In this way, users are automatically assigned the appropriate privileges when they become members of a group. Assigning privileges to groups also makes it easier to manage user accounts.

Table provides a brief summary of each of the privileges that can be assigned to users and groups. To learn how to assign privileges, see Chapter 8. Allows a process to authenticate as any user and gain access to resources as any user.

Processes that require this privilege should use the LocalSystem account, which already has this privilege.
