I think that I have my network pretty well locked down. I have a wireless router hooked up to my cable modem with MAC filtering enabled and I use 128 bit WEP encryption to keep the over-the-air-data secure. I have turned off my software firewalls on my PC and my MAC due to the great firewall on the router itself. Is it possible for a drive-by hacker to access information on my computers through the individual wireless adaptors that are on each computer? Or would they have to gain access through the router itself (which is what I am thinking)? If they have to go through the router, then I can just leave the software firewalls off, but if they can gain access through the wireless adaptors then I need to turn them on. That's why I'm asking. Thanks in advance for the info.
