Network Security on a Small Business Network
Posted on 2004-04-14
I have a network of 10 PCs, most linked through an old netgear 8 port hub and the rest linked direct, to a cheap Dlink DI604 firewall / router / hub to a 2MB broadband cable modem connection. 6 of the machines are test machines.
I have best practises in place on email, downloads, viruses etc. The network works fine and scalability is ok for the time being. I don't want to lose the 10MB hub because its good to see/test the software running over a slower network.
Some of the machines contain sensitive information including customer data and military data
I just want to know whether the di604 is breakable or hackable and if so can I do anything to secure it.
I would like to run tests but have no machines outside of the firewall and I don't stand a chance of understanding nmap.
