Discussion Overview

The discussion revolves around the adequacy of wireless security measures to protect confidential medical information, particularly in the context of setting up a wireless internet connection for a doctor's home. Participants explore various security protocols and configurations, expressing concerns about the inherent vulnerabilities of wireless networks.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant expresses concern about the security of wireless networks, particularly for confidential patient information.
  • Another suggests extreme measures like wrapping the house in metal mesh to enhance security, alongside practical steps like changing default passwords and limiting access by MAC address.
  • A different viewpoint recommends using a Cisco Access Point with Dynamic WEP and TKIP for encryption, along with MAC and LEAP for authentication, while also advising against broadcasting the SSID.
  • Some participants note that most routers support WEP and MAC address filtering, but express skepticism about the effectiveness of WEP due to its flaws.
  • There is a suggestion that hiring a tech professional might be necessary for proper setup if security is a significant concern, given the inherent insecurities of WLANs.
  • One participant downplays the need for extensive security measures, suggesting that MAC address filtering and dynamic WEP should suffice.
  • Questions arise about the ease of controlling SSID broadcasting, with confirmation that it is typically an option on the router.

Areas of Agreement / Disagreement

Participants express a range of views on the adequacy of various wireless security measures, with no consensus on a single approach. Some advocate for more robust security configurations, while others believe simpler measures may be sufficient.

Contextual Notes

Participants acknowledge the limitations of WEP and the potential ease of bypassing MAC address filtering, indicating that security measures may not be foolproof. The discussion reflects uncertainty regarding the best practices for securing wireless networks in sensitive contexts.

Who May Find This Useful

This discussion may be of interest to individuals setting up wireless networks for sensitive applications, particularly in medical or confidential environments, as well as those seeking to understand the implications of various wireless security measures.

My dad just bought a laptop and he wants to setup wireless internet for him and my mom. Which translates to, he wants me to setup wireless internet. But the problem is he is a doctor and will probably have confidential patient info on his computer, I have don’t have much experience in wireless security measures. All I really know is that it isn’t secure. Any thoughts or recommendations would be helpful.

Thanks,

Step 1. Wrap house in metal mesh
Step 2. Change the default password
Step 3. Limit access by MAC address
Step 4. Change WEP keys periodically

If you do step 1 you shouldn't have to do steps 2-4, but in the event that you don't do step 1 then you can find the instructions for steps 2-4 in the router manual.
 
Better still Use a Cisco AP and:

Use Dynamic WEP and Tkip on for encryption
and use MAC and LEAP For Authentication
And finally do NOT broadcast your SSID name

Even better than a house wrapped in metal mesh :smile:
 
Haha, I don't think my parents would go for step 1, but thanks duardo. Can most routers use WEP and filter MAC addresses?
 
All wireless routers support WEP and I'm almost certian they also do MAC address filtering.
 
Yeh most do, WEP is flawed tho... So it is better if you can use Dyanmic WEP and change keys every so often...

Make sure you do not broadcast your SSID also as this is inviting crackers to you, Security through obsecurity is better than non at all

MAC address filter is also better than nothing but is very easy to by-pass by changing your MAC address to one that is Authed on the AP.

If Security is a big deal, you should hire a tech to come and set everything up, because the nature of the beast with WLAN's is that it is insecure but with additions of correct protocols and configuration it can be very secure!
 
Security isn't a huge concern. It sounds like MAC address filtering and dynamic WEP should be sufficient.

Is controling broadcast of the SSID just a setting on the router?
 
yes, typically an option on the Access Point (Wifi Router)
 
Thanks for your help. I will be back if i have any trouble, but i think i can handle that.
