Description

Create a /etc/motd file which displays, post initial logon, a statutory warning message. The creation of a /etc/motd file which contains a statutory warning message could aid in the prosecution of offenders guilty of unauthorized system access. Audit: compares `ls -ld` mode (this mode or more restrictive), owner and group with the CIS values; ACLs are not evaluated.
