SSH Hardening

The root user has the highest rights. For security purposes, you are advised to disable the root user's permission to remotely log in to the server in SSH mode to improve system security. The procedure is as follows:

  1. Log in to the node where MindIO ACP is installed.
  2. Open the /etc/ssh/sshd_config file.
    vim /etc/ssh/sshd_config
  3. Press i to enter insert mode, locate PermitRootLogin, and set its value to no.
    PermitRootLogin no
  4. Press Esc, type :wq!, and press Enter to save the changes and exit.
  5. Make the configuration take effect.
    systemctl restart sshd
