Thwarting ’stealth attacks’ a wireless security must

21.02.2005


The profusion of wireless communications in homes, in coffee shops and even on battlefields presents us with fantastic new conveniences -- but also new security problems. Indiana University computer scientist Markus Jakobsson will discuss "stealth" attacks over wireless networks, which can disrupt communications and endanger personal information. One such attack is "denial of service," in which devices are overloaded with so much incoming information they cease functioning properly.



Jakobsson will also discuss "man in the middle" attacks, in which a miscreant invisibly inserts himself into the communication path of two wireless devices, such as cell phones, PDAs, or wireless-enabled laptop computers.

By manipulating software protocols, a man-in-the-middle attacker can silently pass information between two legitimate points while listening in to the wireless conversation, gleaning sensitive personal information or just plain sabotaging the connection. Stealth attacks over wireless networks threaten the security of personal information, online banking and purchasing. Such attacks may also endanger military personnel, who increasingly rely on wireless communications for maneuvering orders and reconnaissance. Defending against stealth attacks in the civilian sector, Jakobsson argues, will require a concerted effort to develop and distribute new software.


Jakobsson is an associate director of the IU Center for Applied Cybersecurity Research and an associate professor in IU’s School of Informatics. A stealth attack FAQ written by Jakobsson is here: http://www.stealth-attacks.info/.

"Stealth Attacks on Wireless Networks"
Saturday, February 19, 9:45 - 11:15 a.m.

Jakobsson and colleagues will present new findings and position statements on Internet security during a press conference on Saturday, Feb. 19, at 8:30 a.m. in the Marriott Wardman Park Hotel’s Taft Room.

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
