Discussion

Display of a standardized and approved use notification before granting access to the publicly accessible operating system ensures privacy and security notification verbiage used is consistent with applicable federal laws, Executive Orders, directives, policies, regulations, standards, and guidance.

Check

From the ISPF Command Shell enter: ISHELL

Enter /etc/ for a pathname - you may need to issue a CD /etc/ select FILE NAME inetd.conf

If Option -h is included on the otelnetd command, this is a finding.

Fix

Configure the startup parameters in the inetd.conf file for otelnetd to exclude option -h. Note: -h indicates that the logon banner should not be displayed.
