Description
This service is used to test the integrity of TCP/IP packets arriving at the destination. This chargen service is a character generator service and is used for testing the integrity of TCP/IP packets arriving at the destination. An attacker may spoof packets between machines running the chargen service and thus provide an opportunity for DoS attacks. Disable this service to prevent attacks unless testing the network.

Who does this work

5 NICE work roles and 5 EC-Council certifications.

This is an inference across published mappings, not a single claim by anyone. This check maps to a control, which maps to a Cybersecurity Framework outcome, which NIST assigns to the work roles below. EC-Council separately maps its certifications to those same roles.

A certification prepares someone for a role. It is not evidence that a holder is qualified, and neither NIST nor EC-Council has stated that any certification here addresses this check.

Work-role assignments published by NIST (NICE Framework Components 2.2.0 and the CSF 2.0 OLIR crosswalk). Certification mappings published by EC-Council.

Check Text (C-215376r958478_chk)

From the command prompt, execute the following command: # grep "^chargen[[:blank:]]" /etc/inetd.conf If there is any output from the command, this is a finding.

Fix Text (F-16572r294580_fix)

In "/etc/inetd.conf", comment out the "chargen" entries by running commands: # chsubserver -r inetd -C /etc/inetd.conf -d -v 'chargen' -p 'tcp' # chsubserver -r inetd -C /etc/inetd.conf -d -v 'chargen' -p 'udp' Restart inetd: # refresh -s inetd
