Description
The dhcpcd daemon receives address and configuration information from the DHCP server. DHCP relies on trusting the local network. If the local network is not trusted, then it should not be used. To prevent remote attacks this daemon should not be enabled unless there is no alternative. Satisfies: SRG-OS-000095-GPOS-00049, SRG-OS-000480-GPOS-00227

Who does this work

10 NICE work roles and 9 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-215355r958478_chk)

If the DHCP client is needed by the system and is documented, this is Not Applicable. Determine if the DHCP client is running: # ps -ef |grep dhcpcd If "dhcpcd" is running, this is a finding. Verify that DHCP is disabled on startup: # grep "^start[[:blank:]]/usr/sbin/dhcpcd" /etc/rc.tcpip If there is any output from the command, this is a finding.

Fix Text (F-16551r294517_fix)

Disable the system's DHCP client. In "/etc/rc.tcpip", comment out the "dhcpcd" entry by running command: # chrctcp -d dhcpcd Reboot the system to ensure the DHCP client has been disabled fully. Configure a static IP for the system, if network connectivity is required.
