Improper Login Banner (telnet)


Summary

SARA has determined that the telnet login banner is not adequate for proper security.

The problem

SARA conducts a simple test on the pre-login banner of a telnet session by looking for the word Unauthorized or unauthorized. If neither word is found, a warning is reported in the SARA database.

Fix

Build a proper pre login banner. For example, in Linux systems, the pre login banner is contained in /etc/issue.net.
