Enhanced Security: Restricts privileges to only trusted users.Sudo users offer a flexible and secure approach to system administration, granting necessary privileges to trusted users while maintaining control and mitigating potential risks associated with unrestricted access to administrative functions. Using sudo helps maintain a separation of regular user privileges and administrative privileges, reducing the risk of accidental system changes or unauthorized actions. Once authenticated, the command is executed with the privileges of the superuser or root. When a user with sudo privileges wants to perform a command with elevated privileges, they simply need to prepend the command with “sudo” and enter their password to authenticate. This allows system administrators to delegate certain administrative tasks to trusted users without giving them full root access, which can help enhance security and restrict unauthorized actions. ![]() Sudo users are typically granted the ability to run specific commands or perform certain administrative tasks by modifying the sudoers file, which is a configuration file that defines the permissions and privileges associated with sudo. Sudo privileges are often necessary for performing administrative tasks like managing and troubleshooting system configuration, installing software, and editing system files. The term sudo stands for “superuser do,” and it is a command that gives users the ability to perform system-level tasks without compromising the security of the entire system. ![]() Instead, admins can create accounts for users that only have the access they need to perform their tasks – and no more (a principle known as least privilege). On Linux servers, allowing direct root access increases the risk of accidental or unauthorized changes that can harm your system. ![]() Secure Your Amazon Linux Instance with Sudo.
