The Dynamic Host Configuration Protocol (DHCP) is a service that allows machines to be dynamically assigned IP addresses.
Unless a system is specifically set up to act as a DHCP server, it is recommended that this package be removed to reduce the potential attack surface.
Run the following commands to verify isc-dhcp-server is not installed:
# dpkg-query -s isc-dhcp-server &>/dev/null && echo "isc-dhcp-server is installed"
Nothing should be returned.
No output (empty result).
Run the following command to remove isc-dhcp-server:
# apt purge isc-dhcp-server
