What also matters is the fact that even though it may be encrypted, it is still sent via... uhm... "plain hex text" would be the best way to put it. The equivalent of the letter "a" in hex is "61". Wireless networks broadcast the letter "a" as "61". Lots of a's would be broadcast as "61616161". If I watched your network and logged all the hex being broadcast, I could simply keep it in some kind of hex/binary editor and quickly find out what is real data and what is encrypted. Using a WEP decryption proggy (by either disclosing the encryption algorithm or using brute-force), I'm sure one could find out the real hex keys, which in my example would translate into the word "dogpoo". I do think that CigarJohnny has it just about as secure as it can get. It may be a little paranoid, but secure nonetheless. |

Leave it to me to think of missiles and chain guns mounted on an SVX.
I'm really behind in this computer stuff.

But this encoding is NOT the same as encryption. When encryption is enabled, your "dogpoo" (646F67706F6F) password might be encrypted as "bE&abQ" (624526616251) in one packet and "Hfbew$" (486662657724) in the next. This is NOT plain-text as you originally suggested and loading it into a hex editor to look for recurring patterns will not help you. It is true that there are programs which can exploit flaws in the WEP algorithm to crack the encryption in a matter of hours or maybe even minutes. Interestingly, due to a flaw in the design, 128bit is not significantly more secure than 64bit. But there are so many networks which don't even have encryption enabled that it hardly seems worth the effort to trying crack it. Mohrds, Sonar and I have a far more secure configuration than "paranoid" CigarJonny. VPN tunnels add an extra layer of more secure encryption on top of the crappy WEP stuff and a firewall ensures that only VPN packets reach the rest of the network. IMPO this is the best way to implement wireless networking because it ensures that even if somebody breaks your WEP, they have no more access to your network than somebody coming in over the internet.

I would definitely agree that setting up a VPN takes that extra step than what I do. Still, it amazes me how many so-called network admins, who make lots more $ than I do, use no security precautions what-so-ever. Absolutely AMAZES me!
