Details
Check Text (C-215342r991589_chk)
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.
Fix Text (F-16538r294478_fix)
Edit the global initialization files that do not contain "mesg n" command and add the following line to the initialization files:
mesg n
