By popular request this is a new wireless version of the Visual Network Threat Level Indicator. This uses a Roving Networks WiFly RN-XV Module to do 802.11 WiFi along with an Arduino to display the threat level on your network.

Network monitoring is very important in todays world. The internet is a scary place. People have taken steps to raise their awareness by installing Intrusion Detection Systems(IDS) such as SNORT.

The problem with most of these systems is that upon first installing them they are vigilantly watched. After a week the allure wears off and they are no longer monitored, silently churning away in the depths of the network.

By moving the visualization outside of the computer we make it easier to notice, providing the information at a glance and to a larger audience.

The Visual Threat Level Indicator (VTLI) requires a network connection and power. It does not need to be directly attached to a computer, this way it can be placed anywhere there is network access.

A python script is run on the IDS which connects the the Arduino and updates the display.

-Wires, solder, other bits and bobs.

-An IDS system running snort. http://www.snort.org
-WiFlySerial libraries: http://sourceforge.net/projects/arduinowifly/
<p>hey..i wanna one question..how do arduino read the snort log? </p>
I'd liked your previous version's LED bargraph better than the tri-LEDs. But COOL and AWESOME project though!!!
Very nice will be much more useful than a wired version.
wow my network would always be on red very cool
Have not thought about snort in forever. Makes me think of the days of satan (software).
