The more puzzling thing is why some offices, which don't mean to be public, don't use basic features.

What about a home network? I was thinking about setting up a wireless router so I could share a DSL connection with a couple of computers. Can I set it up to be secure (provided I make the effort), or am I asking for trouble? [Link] |

Strong firewall protection Wireless 802.11ABG using WEP, WPA, WPA2, etc can be attacked using packet sniffers to determine: 1. Your network key. WEP is part of the IEEE 802.11 and uses RC4 for encrypting and CRC-31 (If I remember) for the authenticity. It's network key is cracked in about 5 minutes -- not matter the password length. WPA2 is a good bet. I can help you out with setting up your wireless. First: What kind of router do you have?

| Sensi Deactivated User 106 Posts 4/07 | Posted - Apr 18 2007 : 10:55PM I can run several programs through Linux/Windows(AirJack, Kismet, etc) and find your SSID in 3 seconds. Remember: Hiding the SSID means the computers who you allow to connect DISPLAY the SSID in cleartext to the packet sniffer. In addition with SSID broadcasting disabled it is much easier to set up a disassociate frame to grab hold of the entire network key at once in the first place. In addition: Hiding your SSID actually requires your router to send out more packets to the computers it needs to communicate to. Hence, making cracking the network key a whole lot faster. Post edit: Another way to look at it is this. The router has the SSID broadcast off. Yet when you turn on your laptop to connect to your home network -- the SSID name and other important information -- is sent unencrypted to the router. All it takes is someone to run a packet sniffer 24/7 to nag your logins, SSID, and more. Remember me? Spew...[SonyVAIOFE790]C2D2.33ghz. 2GB RAM. Nvidia GO 7600. Linux.

| Sensi Deactivated User 106 Posts 4/07 | Posted - Apr 18 2007 : 11:58PM But to help you out really quick before I sign off: Although there is debate right now about Draft N (the new high speed wireless) it is probably in your best interest to avoid it, for now. But if you are interested these are good choices: D-link DIR665 or LinksysWRT350N. For not Draft N wireless (leaving you ABG): LinksysWRT54G or GX is a decent one. Some complain. There really isn't any "perfect" router. If you want to play video games obviously you need better routers. Yes. Thank you.--------- Remember me? Spew...[SonyVAIOFE790]C2D2.33ghz. 2GB RAM.

| Sensi Deactivated User 106 Posts 4/07 | Posted - Apr 19 2007 : 9:53PM There are ways to greatly reduce the chance -- and by this we mean eliminating the people who are good hackers from the genius hackers. There is an expansive difference between the two. Always remember: Wireless is a riskier than wired. If you choose wireless: Change network keys often, firewall, proxies, PGP, and use the best security model your router allows. [Link] |
