Questions on Wireless Security
Friday, November 30th, 2007Let me first state that I am usually not one to doubt others research, but I just read this article stating that an Professor in Australia and his team at Queensland University of Technology who have created what has been claimed to be an amazing way of identifying intruders on a wireless network by use of the following method;
When reading this a question seem to come to mind.
Radio frequency are susceptible to several forms Radio Frequency Interference (RFI) from a number of natural and man-made occurrences ranging from pine needles and heavy rain to microwave emissions. With this being said, what would be the signal attenuation and degradation threshold have to be sent at before this product is not throwing “false positives” throughout the day making a poor security guys job a living nightmare. If you have any IDS installation experience you will appreciate the threshold headache.
In an environment with a large amount of RFI which fluctuate daily, e.g. Philadelphia; this would required the reporting thresholds to be so high, would this technology truly be able to distinguish between interference and an intruder adequately? I am skeptical.
I will commend the team on an approach that may be a step in the right direction, but it could not stand alone as a security product. Maybe by combining it with other preexisting technology such as AirDefense WIDS Solution we are getting closer to a security wireless network, but again that is years to come.
Please leave some comments and let me know what your thoughts are.
