The recommendation is to edit the /etc/ssh/sshd_config file to ensure that privilege separation is enabled. Setting privilege separation helps to secure remote ssh access. Once a user is authenticated the sshd daemon creates a child process which has the privileges of the authenticated user and this then handles incoming network traffic. The aim of this is to prevent privilege escalation through the initial root process.
