Default Basic Security in Wireless Networks

There has been a new article posted.

Title: Basic Security in Wireless Networks
URL: http://www.hardwaresecrets.com/article/100

Here is a snippet:
"We can finally say that wireless networks are the standard for connecting computers now. Wireless network cards are for long a standard laptop built-in accessory. Almost all broadband routers a peri..."

Comments on this article are welcome.

Great article!
It's news to me that WPA is considered too weak. (But no problem, since I wouldn't dream on using anything but WPA2 anyway...)

Perhaps some more info about the various ways to name WPA2?
In my router, an Asus, there's just a setting for "WPA" (or WEP), and then you get to chose encryption algorithm and need to know that WPA2 corresponds to AES encryption.
The type of key sharing described in the article is known as "Pre-Shared-Key", usually shortened to PSK, which is the proper alternative for networks with relatively few nodes.

Now you just need to do the corresponding updates to the (from a security perspective) obsolete articles How to Build a Wireless Network Using a Broadband Router and How to Build a Wireless Network Without Using a Broadband Router.

Cheers
Olle

Thanks Olle

As you know each manufacturer uses a different names for their control panel options, making it virtually impossible for me to cover all possibilities... Thanks for letting us know the location on your particular router.

Also thanks for pointing out that these two tutorials need to be updated. As you may have notice, I am updating some older tutorials and these are of course on my list of next tutorials that need to be updated. Stay tuned.

Oh, if you have suggestions of tutorials I could be writting please don't hesitate to post them on "Site Suggestions" forums.

Cheers,
Gabriel.

You mean like I did in this post and this post, only a bit more than ten months ago?

Cheers

In my router, an Asus, there's just a setting for "WPA" (or WEP), and then you get to chose encryption algorithm and need to know that WPA2 corresponds to AES encryption.. . .
WPA2 has only one name. However, you can use WPA and AES together on older wireless routers that don't have WPA2.

Language and naming conventions:
WPA2 is a roaming protocol (facilitates roaming).
It also has the option of either TKIP or AES.
WPA2 isn't the name of any sort of security feature.
Security features are named TKIP and AES.

Here it is:
In a real wireless router, there's no security difference between WPA or WPA2. The security, in both, is the choice of TKIP or AES encryption. Use AES.

And:
WPA + AES has a higher rate of compatibility with client devices than WPA2 + AES. The security of either choice is identical. The name of the desirable security feature is AES.

Sorry, but will are completely ill-informed. WPA and WPA2 are completely different things.

WPA2 completely implements IEEE 802.11i protocol, while WPA implements IEEE 802.11i only partially.

WPA2 uses AES-CCMP encryption algorithm, WPA uses RC4.

The key generation process is completely different on WPA2 from WPA.

This subject is really long to discuss in a simple message, I highly recommend you to read this book:

I suggest that WPS (or QSS by other makes) on your router or IP account be disabled prior to root and user passwords changes. Chances are your wifi would have already been hacked if you have used WPS or QSS. I can't for the life of me figure out out why my adapter manufacuter calls QSS "secure"

Again, another great article from HWS even when written in August 2009. You Guys ROCKS!
