SSH Hardening

During the deployment and installation of OmniOperator, you need to connect to the server through SSH. The root user has all the operation permissions. Logging in to the server as the root user may pose security risks.

You are advised to log in to the server as a common user for installation and deployment and disable root user login using SSH to improve system security. The procedure is as follows:

Check the PermitRootlogin configuration item in /etc/ssh/sshd_config.

• If the value is no, root user login using SSH is disabled.
• If the value is yes, change it to no.
