What kind of security is recommended for the owner of a small personal cluster? Where should the owner of a small, personal cluster go to learn about security? Doing searches tends to give a few "head in the sand" sites but predominantly seem to be oriented for the security professional.
I maintain a small 3 node personal cluster used for my part-time PhD studies in chemistry. So far I've just kind of been hoping that I'm too small to bother with and that the firewalls (Linux and switch) between my boxes and the cable internet do something. I do use ssh for cluster communications, and have disabled the reknowned unstable services such as ftp. RGB mentioned running services on non-standard ports. This seems like a good idea to further reduce the probability of successful attack. I'll look into this in a couple weeks when I'm laid off and will have more time on the IT side of things. Are there any good sites aimed at the small user to slowly learn a little bit about security? Or are the only choices to do security full-time or forget about it entirely? What sorts of security do other here have on their personal clusters? Is maybe the simplest idea to just disable TCP/IP across the internet network while not in use and enable it when it needs to be up? Thanks, Mark E.
