generally whatever can be done in the earliest possible layer should be done there
security is always a layered thing (network, firewall, application firewall, application)

things like rate-control and limit concurrent connectios from a source-ip
should be done in iptables or if possible even a device before the server

it *can* be done with modsec, but where ever you can catch attacks a layer before do so
