Check Text ( C-21796r488591_chk )
Check global initialization files for the presence of "mesg -n" or "mesg n".

Procedure:
# grep mesg /etc/.login /etc/profile /etc/bashrc /etc/environment /etc/security/environ /etc/csh.login /etc/csh.cshrc

If no existing global initialization files contain "mesg -n" or "mesg n", this is a finding.
Fix Text (F-21795r488592_fix)
Edit /etc/profile or another global initialization script and add the mesg -n command.
