Commonly Used Special Identity Groups
Anonymous User Security Enhancement In and Windows 2000, the operating system makes every user authenticated by the domain and all potential anonymous users members of the Everyone group because the Authenticated Users, the Anonymous Logon, and the Domain Guests groups are automatically made members of the Everyone group. This membership is provided to allow anonymous users access to Active Directory objects. To provide stricter control of access to resources, you must remember to remove the Everyone group from the access control list for the resource. Because administrators often do not realize that anonymous users are members of the Everyone group, these users might inadvertently be granted access to resources intended only for authenticated users.
In Windows Server 2003, the Anonymous Logon group is no longer a member of the Everyone group. Therefore, anonymous users attempting to access resources hosted on computers running Windows Server 2003 will be impacted. If anonymous users must be granted access to resources, you must explicitly add the Anonymous Logon security group to the access control comptia security+ exam list for the resource and provide the required permissions. If anonymous users must always be granted access to resources, you can change the new Windows Server 2003 default security setting for the Everyone group by enabling the group policy Network Access: Let Everyone Permissions Apply To Anonymous Users, located at Computer ConfigurationX Windows SettingsX Security SettingsX Local PoliciesXSecurity Options. For more information about using Group Policy, refer to Chapter 11, “Administering Group Policy.”
To protect access to the domain or a computer, every user account should have a strong password. A strong password is at least seven characters long, does not contain all or part of the users account name, and contains at least three of the four following categories of characters: uppercase characters, lowercase characters, base 10 digits, and symbols found on the keyboard.
This is what happens to objects that are orphaned. Objects are orphaned when their parent container is deleted during replication. If you were faced with the actual situation described in this troubleshooting lab, you could move the user accounts from the LostAndFound container to the Admin container.
A security mechanism that determines which operations a user, group, service, or computer is authorized to perform on a computer or on a particular object.
A rule associated with an object to regulate which free it certification users can gain access to the object and in what manner. Permissions are assigned or denied by the object’s owner.
