Reverse Firewalls As An Anti-Spam Tool
An anonymous reader writes "VeriSign's principal scientist Phillip Hallam-Baker believes one answer to stopping spammers and even crackers is by using reverse firewalls. He says reverse firewalls should be embedded in every cable modem and wireless access point for home users. "A traditional firewall is designed to stop attacks from the outside coming in; a reverse firewall stops an attack going out," Hallam-Baker said. Apparently, a reverse firewall would reduce the value of recruiting your home PC as a member of a botnet because "normal users have no need to send out floods of e-mail, which reverse firewalls can stop, but they do allow a normal flow of e-mail. ""
I, being the ubergeek that I am, already have a 14k^H^H^H^H "reverse-firewall".
No hackers for me, no siree!

Can it it be configured to block port 1984?
Nothing in the world is more dangerous than sincere ignorance and conscientious stupidity.
However, the security model in 802.11 may not be enough to prevent an attacker to get access to the intranet.

Couple of relevant things:
Windows XP SP2 will include a reverse firewall that is enabled by default. Unfortunately it will be released, for compatibility reasons, after Duke Nukem Forever.
Principle Scientist for Verisign? The same company with the terrorists/geniuses (what's in a name?) who decided to hijack the DNS system and send it to a search portal that pays them money each time it gets used? Thanks a lot. I'll take advice from a great company like that.

I just think it's funny that VeriSign's "chief scientist" said we should use "reverse firewalls" ... I'll foil his plans by installing a reverse router with dual reverse Ethernet switches between my hosts and my cable modem. And I'll connect it all using my reverse CAT6 cables. This way, by the time a packet arrives at the reverse firewall it will already have been reversed...in which case...uhhh...it will be re-reversed and forwarded normally. Yup.
I'm gonna go to reverse sleep now.
