DHCP
1 Rule
The Dynamic Host Configuration Protocol (DHCP) allows systems to request and obtain an IP address and other configuration parameters from a server.
This guide recommends configuring networking on clients by manually editing the appropriate files under
/etc/sysconfig
. Use of DHCP can make client systems vulnerable to compromise by rogue DHCP servers, and should be avoided unless necessary. If using DHCP is necessary, however, there are best practices that should be followed to minimize security risk.
Disable DHCP Server
1 Rule
The DHCP server
dhcpd
is not installed or activated by default. If the software was installed and activated, but the system does not need to act as a DHCP server, it should be disabled and removed.
Uninstall kea Package
Medium Severity
If the system does not need to act as a DHCP server, the kea package can be uninstalled.
