The protocol that should be used to establish a secure network connection for backups is SSH.
<h3>Secure Shell</h3>
SSH stands for <u>Secure Shell</u>. SSH is a <u>protocol that allows users to remotely control and modify servers</u>. SSH is commonly used by administrators to manage certain systems or applications remotely. So the admin can enter the computer via the network, then run various commands to modify or manage files from one computer to another.
SSH has several crucial functions for managing data transfer traffic. Specifically, the following are the functions and benefits of SSH:
- Securing remote access to SSH-enabled systems or network devices for the user and processing them automatically.
- SSH will automatically terminate the connection if there is suspicious activity on the connection used. So you can avoid various cyber threats such as IP and DNS spoofing, data manipulation, illegal tracking, and others.
- Perform automatic and secure file transfers.
- Launch commands securely on remote devices or systems.
- Perform secure component management of network infrastructure.
