SUDO and SSH
A sudo concept in Linux and the purpose of SSH:
Sudo (superuser do):
Sudo is a program for Linux-based systems that allows specific users to use particular system commands at the root level of the system. When you use the’sudo’ command, you temporarily gain administrative access to perform tasks that require higher privileges. For example, you might use Sudo to install software, update the system, or edit configuration files in directories that regular users don’t have permission to modify.
SSH (Secure Shell):
SSH is a secure shell that allows users to log in with a safe and encrypted mechanism into the remote computer. SSH is widely used by system administrators and developers for secure access to servers and cloud environments. The default port for SSH is 22, and it relies on public-key cryptography to authenticate users securely without exposing sensitive credentials.
