I have 4 computers. The cable modem is connected to the router and my computers are connected to the router. The router has a firewall, is this enough protection against hackers or do I need to install and enable a firewall on each of the computers?

best practice

by CG IT In reply to Firewall

best practice for firewalls is to have a layered defense that hackers have to fight their way through. If you have a firewall on the router, Great. If you have firewalls on the computers, thats even more protection.

I agree

by Dumphrey In reply to best practice

with CG. I have 3 computers behind my routerfw and I use a fw on each of them. I rarely if ever get hits on them, but when I do, I smile, knowing I am that much more secure.
They will never h4l<z0rz my pr0n!
Just kidding.
Seriously, with an many good, free firewalls thata re available for download, there is no real reason not to download a few and play with them until you find one you like. Ghostwall, ZoneAlarm, Commodo, PCTools (no experience with it, but its free), Sygate, and many others...

The layered approach is best.

However, with a decent router/fw, the Windows FW is probably sufficient on each PC.

There are free/inexpensive fw's out there that do a better job, but they'll also slow your traffic down and consume more system resources.

Try a few games of Uplink...

and you'll come to the same conclusion.
