When it comes to our computers, most of us are familiar with the terms Administrator and User profiles. Users are compared to the general population, whereas Admins are compared to God.

What about Domain Administrator, Domain User, and Local Group accounts? There are numerous more sorts of profiles that grant access to machines, servers, and network settings at various levels.

Who should be an Administrator on your network?

Administrator access to your network should not be granted to any ordinary user accounts. Users with Administrator access as part of their regular user account could unintentionally wreak a lot of damage if they were infected with a virus that deletes data, for example.

A “Windows Active Directory Domain” is usually present on a Windows network, and it includes user accounts and controls permissions for each user as they log on.

If a user requires special access, they should be given information about an Administrator account with the necessary level of access.

Domain Administrator Accounts

Special Administrator accounts should be created with a reasonable level of network access to allow users to do administrative activities, and the credentials should be distributed to users who require occasional Administrator access. The administrator is a common user name for an Administrator account. So there you have it.

It is recommended that the default built-in Administrator account be disabled and a new Administrator account with a different name be created. NetworkAdmin, for example. Users utilize administrator accounts to perform actions that require special rights, such as installing software or changing the name of a computer.

These Administrator accounts should be audited on a regular basis, with a new password and confirmation of who has access to them.

Windows Domain Administrator Groups

There are multiple Security Groups on a Windows network that have high levels of access to various portions of the network. These groups should be reviewed on a regular basis to ensure that only Administrators are members. The following are the default groups:

  • Administrators
  • Domain Administrators
  • Administrators of Schemas
  • Admins in the corporate world

Other groups with high levels of access that have been manually created are possible. These should be written down and included in the auditing process.

Domain Service Accounts

The Service Account is a specific sort of user account that has privileged access to certain portions of your network. Service Accounts are user accounts that are used by software (often on a server) to perform automatic functions such as backups and anti-virus management. These services should never be configured with Administrator account credentials; instead, your network should have at least one dedicated Service Account.

Domain Guest Accounts

The visitor is the default guest account in Windows. These guest accounts are the first point of entry for criminal hackers, and they should be deleted immediately and indefinitely. If a visitor account is required, it should not be named Guest or something similar.

Domain User Accounts

These are the standard user accounts that employees use to log on to a computer and carry out their daily tasks. They should not be given any special permissions that could lead to data loss or damage. These user accounts are usually members of the Domain Users Security Group.

It may be required to provide users special or administrative permissions in specific instances. This should only be available to Local Admins (they are Administrators only on their own computers, and not on the Domain).

Local Accounts

These accounts are identical to Domain accounts, however, they are only available locally. A computer or a server can be accessed locally. Administrator accounts, regular user accounts, and guest accounts are all examples of local accounts. On workstations, the built-in Administrator and Guest user accounts should be disabled at all times, and on servers, the built-in Guest user accounts should be disabled at all times.

Local Groups

Administrators are the default Security Group for computers and servers. This group's membership should be restricted to the Domain Admins domain group.

Types of user accounts

User accounts are used to authenticate, trace, log, and monitor services, regardless of which operating system we use. When we install an operating system, it creates several critical users accounts for us to utilize immediately after the installation. Typically, four sorts of user accounts are created during the installation: system account, superuser account, normal user account, and guest user account.

System accounts

Different services running in the operating system use these accounts to access system resources. These accounts are used by the operating system to determine whether or not a service that requests system resources is permitted to do so. When services are installed, they usually establish the necessary accounts on their own. Services use these accounts to access resources after they've been installed. You never need to know about these accounts unless you're a system or network administrator.

Superuser account

This user account has the greatest operating system privileges. This user account is known as the Administrator account in Windows. It's referred to as the root account in Linux. This user account has full access to the operating system, including the ability to change system files, install new software, remove existing software, start and stop services, create new user accounts, and delete existing user accounts.

Regular user account

This user account has a modest level of access. This user account is not permitted to modify system files or properties. This user account is only allowed to conduct things that it is authorized to accomplish, such as creating files and directories, running applications, changing environmental variables, and so on.

Guest user account

This is the least privileged user account. It is unable to alter any system files or properties. Typically, this account is used to gain temporary access to the system for purposes such as browsing the internet, watching movies, or playing games. This account is established automatically after the installation of Windows. If necessary, we must manually create this account in Linux after installation.
