testing my network security?
How can I use Linux to test for weaknesses in my network. Basically what tools?
I work at Kinkos and we have a laptop area where people can hook up their laptops and use our connection to get to the internet. When I set this up for them I had some reservations about it, now I want to know how much..if at all, this will compromise our network.
I'm not a hacker and really have no idea how to do it, but to someone who knows, I doubt there is anything to really stop them. Still, I want to make sure it's not easier than it has to be.
Just using Windows and ipconfig with some crappy tools I know all the IP addresses the server uses. ( I knew these already but I just basically verified I could also find it out with little effort)
I'm not looking for a way to break in, I just want to know about potential weaknesses so they can be looked into further and fixed if necessary.
