=> the simplest (and most efficient as a rogue client can for instance
flood the server with junk queries) is to use a firewall feature to
drop messages on the floor. At the Kea server level the standard way
is to create a client class which matches all other clients and
to guard subnets or pools with this class so not resource will be
available to it. You can also write a hook to filter out messages
but it requires to write some code (vs a config update).

PS: I cited the hook because it is the standard way to plug an
authentication/authorization service to Kea.
