Command "mesg -n" allows only the root user the permission to send messages to your workstation to avoid having others clutter your display with incoming messages.

Check Content

Check global initialization files for the presence of "mesg n" command by running: 

# grep "mesg" /etc/profile /etc/environment /etc/security/environ /etc/security/.profile /etc/csh.login /etc/csh.cshrc 
/etc/profile:mesg n
/etc/environment:mesg n

If any global initialization file does not contain "mesg n", or it contains the "mesg y" command, this is a finding.
