Rationale
The /etc/ssh/sshd_config file needs to be protected from unauthorized changes by non-privileged users.
Audit Procedure

# stat /etc/ssh/sshd_config
Access: (0600/-rw-------) Uid: ( 0/ root) Gid: ( 0/ root)
Expected Result
Uidis0/rootGidis0/root- Access is
0600/-rw-------(no permissions for group or other)
Remediation

# chown root:root /etc/ssh/sshd_config
# chmod og-rwx /etc/ssh/sshd_config
