This may a bit off topic, but I am talking about a debian base network, and I sense that many of the people on this list have admin expertise.
I have a small home office network. I recently set up samba and in the process realized I'm not all that honed on security issues. My concern is this, when I set up something like filesharing, I'm just doing this for the efficiency of my two person software development company; the other employee is my wife. In this environment, I generally just set things up as loose and quick as possible. My question is, am I wrong for thinking that security isn't of much concern, in regards to something like samba file sharing, for our two user network. My theory is that as long as I keep my network shutdown to outside access, everything is cool. For instance, I generally don't forward any ports from my DSL router into my local machines. On occasion I'll open 80 to let my clients do some testing. Am I right in assuming this means I don't have to tighten up something like file sharing?
