Hi everyone, I have been playing with my own network at home trying to teach myself something about computer security, anyway working inside my own network is fine and I've learned a few things. Today I asked my boss if I could scan my home network from work, he said OK, (I work in an auto dealer and they let me install a WAP so I could use my laptop in the shop) So I scan my network and all ports come back as filtered, I am running behind a router/firewall and IP's are 192.168.1.*, I'm scanning the IP that my ISP assigns me, not 192.168.1.*.
Basicly I wanted to see what a hacker/cracker would see if they scanned my IP.
First, am I actually scanning my firewall or one of my ISP's servers? Second, could I safely assume that since all ports show filtered that I would be safe from a cracking attempt?
If not how would someone go about getting inside my network if they don't know that it exist? Is using the out of the box default settings on a router/firewall(Linksys) a good idea?
