SV-99219r1_rule The DHCP client must be disabled if not needed.

Vulnerability discussion

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

Check content

Check that no interface is configured to use "DHCP": # grep -i bootproto=dhcp4 /etc/sysconfig/network/ifcfg-* If any configuration is found, this is a finding.

Fix text

Edit the "/etc/sysconfig/network/ifcfg-*" file(s) and change the "bootproto" setting to "static".

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.
