RFI Survey
WLAN Vulnerability Detection 



>>> RFI Survey -- General Information


         Troubleshoot wireless network performance problems.

         Localize interfering wireless networks and devices.

         Determine wireless network vulnerability to intrusion.

         Provide area maps showing wireless router locations.

         Provide attributes of detected wireless networks.

         Evaluation of office/home network performance.

         Indication of security level and actions to improve.


>> Isolate Interference Problems ...


We are conducting surveys in the Northern Virginia area to help business and home computer users with issues related to their wireless networks, or wireless local area network (WLAN), and other radio-based communication equipment -- performance problems caused by neighboring WLANs and other sources of radio frequency interference (RFI) in the immediate vicinity. 


>> Eliminate Security Risks ...


We also identify wireless network node security vulnerabilities -- wireless routers, wireless capable computers and other network connection points, that can allow and unauthorized user or group to connect and access private resources and assets.


LeveL10 can conduct a detailed RFI survey of your particular location and immediate vicinity, provide you with the detailed report results and a complete explanation of the findings.


>> Protect Your Privacy ....


We offer assistance to anyone experiencing WLAN connection problems, or having concerns about information privacy and protection of assets.


During this survey of potential RFI sources, we note the security level and intrusion susceptibility of detectable WLANs.


>> Be Aware of Your Environment ...


WLAN Location and Identification -- The survey report data shows the geographic locations of WLAN access points (AP) -- latitude and longitude of detected 802.11 wireless router radio sources. 


The report data indicates the service set identifier (SSID) and other network parametric information that is publicly "broadcast" by the wireless router.  This information is typically used to identify the operating characteristics and allow intended connections.  This is used to establish a protocol for connecting devices.


This information also helps identify WLANs that may interfere with each because of physical proximity and/or operation on the same or adjacent radio frequency (RF) channels. 


If the owner changes the SSID during WLAN equipment configuration, the report shows this name rather than the vendor's default name.  This is effectively the real name of the network.   The router broadcasts the name so that anyone trying to connect into the network can select the right one. 


Network Security -- The report also indicates if data encryption is active, such as the Wired Equivalent Privacy (WEP) method.  The wireless router installer must enable this during configuration of the router.  For typical WEP, a unique and private "key" value is selected.  Any computer, or other device, attempting a network connection must know this key value. 


WEP only provides limited encryption.  If a hacker captures enough data passing through the network, they can decipher the key.  Programs to do such are readily available.  However, WEP does provide some degree of protection and prevents the casual user from accessing the network.  Other more sophisticated techniques can be used, such as those that frequently rotate the key values.


Unfortunately, many home and small business WLANs are set up with no protection from intrusion -- accidental or deliberate.  This allows anyone, up to several hundred feet away, to access the owner's network, computers and cable/DSL Internet connection.  This problem is common because the WLAN equipment works "out of the box" without any security settings as the default. 


Individual Site Reports -- LeveL10.us can provide report data on your exact location and vicinity.  This report includes all information we observed on WLAN access points within at least 500 feet of the property address given.  In addition, a perimeter walk of the property line more precisely determines the location and relative signal strength of close-by wireless router APs.  This isolates those that can cause the most interference. 


Neighboring wireless router AP parametric information collected during the site survey can be used to determine the best physical location for your wireless router and which RF channel will provide the best performance.


The report results are only provided to the owner or resident of the property at the address requested.  This report is for the purpose of identifying radio frequency transmissions that may interfere with the operation of WLANs and other radio devices within the property boundaries of the given address.


Available Services -- LeveL10.us can also provide on-site assistance to diagnose any problems, secure your system against threats, and provide performance evaluation and system tuning.



NOTE:  The RFI survey field technician never attempts to access, or connect to, any WLAN or other private commutation channel.  This can only be done with the verified owner's permission and presence when performing diagnostics at the owner's request.  The survey technical never enters private property without the owner's permission.
