SV-38931r1_rule The DHCP client must be disabled if not needed.

Vulnerability discussion

DHCP allows for the unauthenticated configuration of network parameters on the system by exchanging information with a DHCP server.

Check content

If the DHCP client is needed by the system, this is not applicable. Determine if the DHCP client is disabled. # ps -ef |grep dhcpcd If dhcpcd is running, this is a finding.

Fix text

Disable the system's DHCP client. Edit /etc/rc.tcpip, comment out the line starting 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.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
