ACCOUNT TYPES
ROOT ACCOUNT
The root account is a superuser account with elevated privileges. The root account is also sometimes referred to as the "superuser" or "administrator" account.
Root users provide security for some applications and commands.
For best security practice, Never automatically log-in as root.
STANDARD ACCOUNT
Unlike the root account, a standard user account does not have the administrative or superuser rights necessary to perform system-level tasks that could potentially impact the stability and security of the system.
Using a standard user account for day-to-day activities is a security best practice. This practice adheres to the principle of least privilege, which means users are given the minimum levels of access necessary to perform their tasks.
SERVICE ACCOUNT
Service accounts in a Linux environment are user accounts specifically created for the purpose of running services or applications. These accounts are often associated with specific software or services rather than individual users.
Service accounts are designed to provide the necessary permissions and access for a particular service to function properly while adhering to the principle of least privilege. Service accounts are like HTTP for web services or MYSQL for data bases services.
