RE: [squid-users] dos attack protection on proxy

The biggest possible dos against a well run proxy server is something like
codered coming from client machines inside you network aimed at the
outside world... The defense against those type of attacks (not codered
necessarily since that's already been identified) is to monitord your
proxy server for unusual spikes in activity, particulalry if they
originate from a single or small number of hosts...

your proxy server should be running a lot of services visible from outside
your netowrk in most cases anyway, so it should itself be hard to dos from
the outside.
