Functional analysis of six large user groups in Windows operating system

window in Windows systems, the impact of user names and passwords on system security is undoubtedly the most important. It has become an important attack way for many hackers to obtain the username of the computer in a certain way, and then get the password of the username by some means. Even now many firewall software misconduct has emerged, the function has been gradually enhanced, but by acquiring user name and password attack mode still occurs. In fact, by strengthening the Windows system user's permissions, to some extent, security has a great help.

Windows is an operating system that supports multi-user, multitasking, and different users will have different permissions when they access the computer. At the same time, the user rights settings are based on user and process, Windows, users are divided into groups, groups and groups have different permissions, and a group of users and users can have different permissions. The following are common user groups.

1.Users
Normal user group, users of this group cannot make intentional or unintentional changes. As a result, users can run validated applications, but they cannot run most legacy applications. The Users group is the safest group because the default permissions assigned to the group do not allow members to modify the operating system settings or user data. The Users Group provides an environment in which the most secure programs run. On NTFS-formatted volumes, the default security setting is designed to prevent members of this group from compromising the integrity of the operating system and installed programs. Users cannot modify system registry settings, operating system files, or program files. Users can create local groups, but can only modify local groups that they create. Users can shut down the workstation, but not the server.

2.Power Users

Advanced user groups, Power users can perform any operating system tasks other than those reserved for the Administrators group. The default permissions assigned to the Power Users group allow members of the Power Users group to modify the settings for the entire computer. However, Power Users do not have the right to add themselves to the Administrators group. In permission settings, the permissions of this group are second to administrators.

3.Administrators Administrators group, users in administrators have unrestricted full access to the computer/domain by default. The default permissions assigned to this group allow full control of the entire system. In general, you should set the system administrator or a user with the same permissions as a member of the group.

4.Guests Guest Group, the Guest group has equal access to members of the general group of users, but the Guest account has more restrictions.

5.Everyone all users, all users on this computer belong to this group.

The 6.SYSTEM group has the same privileges as administrators, which is not displayed when viewing the user group, and does not allow any user to join. This group is mainly to ensure the normal operation of the system services, to give the system and system services permissions.
