Network printer issue - security? - printer security
Hello, I have two networks connected one with the Internet and has 3 or 4 computers, my network works on it and you have an Internet connection. Currently I have a printer connected to the Internet, and we need to change the network cable around, when I print a page of things about other networks.
What I know is, if I bought a second network card connected to my network printer and the printer does it provide any security issue? Basicially, we could not find a way to my computer to the Internet through the printer and "in" my network secure? It is hardly possible, but I just want to ensure before you go ahead and do it. Thanks

Well, first I would say it is unlikely .... But, hey, everything is possible. If your printer is a connection between the two systems, ie, they could not bridge traffic, among other things? Is your printer firmware intended or designed with security in general funcationality? I think the functionality of the printer are not exactly known for being good routers or firewalls.
In addition, you indicate that the printer is equipped with multiple network cards, so who knows? What we really need to do is look at the details of your particular printer, skimmed milk, in the light manual for the latest firmware and see what options or not in the configuration. It is most likely safer. Take at least, not an easy one and probably just someone who wanted very badly in the safety net is time to get to work on it too. That is, if someone bad enough to have extinguished all of Paris.
I hope this helped .... Absence of more specific information about the printer, there be a lot more concrete answer. (See alsothat even if we can give a concrete answer on that time, there is no way to the printer, new vulnerabilities all the time to access. What is safe today might not tomorrow.)
I am not aware of any routines that you will be held by a printer (but hey, they get something new every day). If everything you do, start an additional network card directly to the printer, a person must be very, very serious piracy off the printer can not act as a router, the program would you need to hack your own printer. I have no idea that even if you can.
There is another way. Locate the port for your printer used to (usually 9100 to print, but many are). Put a router between you and the "Internet" network, firewall, all but the printer port. Transfer the printer port on the IP address of the printer and "install" the IP router. If you are really paranoid, always prints, turn on the router. Whenever you do not turn it off. Beat the cable and swap it would be extremely safe.
I think he digs a hole in your network that way.
Concern for Internet users, while others receive on your PC? If so, you get a firewall on your PC and use the same network for all. You may go, others can not go on your PC when you properly configure the firewall. I think I can even with the firewall in Windows XP if you're not careful.
