What are security risks when running an Erlang cluster? [closed]

It's more a general question in terms of what one has to look out for when running an Erlang system. For example, I know of atom exhaustion attacks. What are other possible attacks and how to make your system more secure?

Running a cluster means they are sharing a cookie, and if one knows the cookie than they can attach to any of your nodes (assuming they are attached to your network) and execute any arbitrary Erlang command or program.

So my thought is that clustered means that there are at least two files (and some number of people) who know what the cookie is (or where to find it).
