Wireless Security with AES
There are myths of wireless being an insecure medium.  While this was true in the past, wireless encryption has since advanced multiple folds to become more secure than a fortune 500 company's local area network.  Encrypting local area network is not a new concept, but Ethernet equipment outfitted with layer 2 or layer 3 encryption are few and beyond affordability for typical company.  Industry survey reflects most users of encrypted local area networks are by government entities and very few make it to the private sectors.  While the wireless encryption protocols used on the first-generation digital wireless LAN networks 10 years ago was easily defeated, the latest advancement in wireless encryption takes over 4 x 10^20 years to break.
Advance Encryption System (AES), the industry standard for wireless encryption is currently the most widely used wireless encryption today.  It is robust and secure for use at the highest level.  In this article we will be looking at the differences and advantages of AES encryption has over other encryption methods such as WEP, WPA, and DES. It is extremely important to have the best wireless encryption available in order to protect valuable information your company has.  Encryption methods such as WEP can be cracked within 10 minutes.  AES encryption can give you peace of mind knowing all your files and information are safe from outside threats. 
Now we will begin comparing the various security methods available starting with WEP.  WEP stands for wired encryption privacy, founded in 1999, is the easiest to break since it does not change its key.  According to industry experts, WEP can be hacked within several minutes using a standard of the shelf personal computer. WEP works by using secret keys or codes to encrypt data.  Both the client and AP must know the key in order for the wireless signal to work.  WEP has 64-bit and 128-bit available for its keys.  Some problems with this kind of security are as follows:
Users rarely change the keys, which gives hackers time to break into the network.
The master key should be used to generate other keys but is used directly.
Another type of wireless encryption is Wi-Fi Protected Access (WPA).  WPA was created in 2003 by the Wi-Fi Alliance and was used to remedy the weaknesses that WEP had. The major upgrade from WEP to WPA was WPA used TKIP or temporal key integrity protocol.  TKIP works with 128-bit key for encrypting and 64 bit key for authenticating and rotate keys during each transmission of data across the network. The transition from WEP to WPA was an easy path and only requires a software upgrade. Some of the upgraded features WPA has over WEP are as follows:
  • Better management of keys
  • The master keys are never used directly
  • Message checking is done with much better integrity

A third type of wireless encryption, DES, (Data Encryption Standard) was released in the 1970's by the National Bureau of Standards. Initially, DES was available in two packages, 32-bit and 56-bit version.  There is major difference between the two versions, first, instead of the 56-bit key, a 32-bit key is used and second the data iteration will only occur 4 times instead of the original 16. For the 32 bits version, there are a total of 4,294,967,296 possible keys available. It would take a personal computer one full day to break it.  The 56-bit version on the other hand takes about 1 million years to break it accordingly to industry sources.        
In 2004, the Wi-Fi Alliance released WPA2, which uses the highest level of
encryption, AES.  This is strongest form of encryption and should always be your first choice. AES has 128-bit, 192-bit, or 256-bit keys for your use.  For AES to work properly all hardware must be current.  You cannot simply apply a simple update and have AES work for you as is the case for WPA. With WPA2, you have different options for enterprise and personal use.  The personal option works by using a pre-shared key (PSK) while the enterprise utilizes EAP and 802.11x for authentication. The biggest and most significant advantage WPA2 has over WPA is that every time data is sent it is encrypted with a unique key, which is never duplicated.  This makes breaking into WPA2 encryption almost impossible as compared to WPA.
According to industry sources, time required to break into WEP is estimated at less than 10 minutes, while WPA with a 21 character password takes approximately 4 x 10^-20 years, and WPA2 even longer. According to the United States Government, AES is secure enough to protect classified information up to the top secret level.

AB54 Bridge Mode versus AP Mode and How to Set It Up

Bridge mode allows the AB54 to communicate with another AB54 to provide layer 2 transparent bridge between two LAN.  Transparent bridge works by passing MAC addresses from one network interface to another.  The AB54 use proprietary means to communicate therefore provide an added layer of security compared to AP mode. The major difference between AB54 bridge mode and client mode is the method of bridging, transparent versus translation.  Client bridge mode was designed for ISP to provide internet connectivity to residential or commercial properties.  Therefore client bridge mode provides added layer of security for ISP establishments and subscriber with translation bridge algorithm. Client bridge mode allows ISP to easily manage large scale wireless networks and tiered services. 
Now we will show how to set up 2 AB54s to operate in bridge mode. First, login into one of the AB54s and go to system properties and select 'bridge mode'. (See Fig.1) Finally, click on 'apply' to save the settings.

 Fig. 1 System Properties
Next, click on the WDS link settings page and enter the MAC address of the remote AB54 you will be connecting to. You will need to select 'enable' under mode. (See Fig.2)  After you are done entering the information, click on 'apply' to save the settings.   

 winter08 help1-2

Fig. 2 Link Settings
The above procedure will also have to be applied to the remote AB54 where the local MAC address of the AB54 will have to be entered into the field.  In addition to applying the WDS settings, the security, channel, and SSID settings must be identical on both units for them to communicate with each other.

License Free Channels - How to choose?

We will now look at channel selection and which channel to use to get the best wireless communication.  In the following examples, management user interface screen captures of Inscape Data outdoor wireless equipment is used to illustrate recommended wireless channel practices.  We will start with the AB54 and CB54 which are both 2.4 GHz radios.  If you have the AB54 you will need to put the unit in client mode by going to system properties and selecting 'client'. Click on 'apply' after you have done that. (see fig.1)

Fig. 1 System Properties

Once in client mode you can click on 'wireless network' on the left side of the menu and you will see a screen as shown in figure 2.

Fig.2 Wireless Network

Click on the 'site survey' button and it will scan and show all surrounding APs and what channel they are on as shown in figure 3.

winter08 help2-3
Fig. 3 Site Survey
From this site survey you can determine the best channel to use. The 3 non-overlapping channels are 1,6, and 11.  All other channels will have interference from adjacent channels and it is not recommended to use them.  You can count the number of devices that are on 1, 6, and 11 and select the channel that is being used the least. This will provide you with the best performance possible.  It is not recommended to use 'smartselect' as this does not stay fixed on one specific channel.  It will take any channel available, which may also be the most congested channel.  Once you have found the channel you will be using you will need to put the radio back in access point or bridge mode and select it there. (see fig. 4)

winter08 help2-4

Fig. 4 Wireless Network


Please note that the site survey tool is only available in client mode and channel selection is only available in Access Point and Bridge modes.

Now we will look at channel selection for the BR108, which is a 5 GHz radio.  All channels available for the BR108 are non-overlapping and range from 5.1 GHz to 5.8 GHz.  A site survey of the area to determine if there are any devices such as microwave towers, antennas, etc which operate on 5 GHz will be very helpful in determining what channel to use.   For example, if you find that there are 2 antennas operating in 5.4 GHz you will know to avoid the channel associated with that frequency.  The channel can be changed in the '5G bridge' page as shown below in figure 5.  After selecting the appropriate channel click on 'update' then 'reboot' to save your changes.

Again, 'smartselect' is not recommended for bridge applications as it will keep changing channels to what is available.
