Researchers from Oxford University’s Computing Laboratory have developed techniques to spot malicious attacks on computer networks, that include the use of Inductive Logic Programming (ILP) techniques to automatically determine the semantics of novel attack strategies.
Intrusions often take place where there are vulnerabilities within computer systems. For example, one of the most common of these is the buffer overflow, where an attacker sends overly long transactions to a server. The aim is to overflow the server’s buffer with code that runs automatically, allowing the attacker to execute malicious commands via the network.
A recent example was the “Code Red” worm released on Friday 13th July 2001. The attack caused havoc for programmes running on Microsoft Internet Information Server and slowed down Internet traffic considerably. No one was able to stop it automatically; few recognised what strategy the attack was using and system administrators had to look for it manually in the registers of their systems.

Experimental progress towards engineering quantized gauge fields coupled to ultracold matter promises a versatile platform to tackle problems ranging from condensed-matter to high-energy physics
The interaction between fields and matter is a recurring theme throughout physics. Classical cases such as the trajectories of one celestial body moving in the...
Soft robots have a distinct advantage over their rigid forebears: they can adapt to complex environments, handle fragile objects and interact safely with humans. Made from silicone, rubber or other stretchable polymers, they are ideal for use in rehabilitation exoskeletons and robotic clothing. Soft bio-inspired robots could one day be deployed to explore remote or dangerous environments.
Most soft robots are actuated by rigid, noisy pumps that push fluids into the machines' moving parts. Because they are connected to these bulky pumps by tubes,...
Researchers at TU Graz are working together with European partners on new possibilities of measuring vehicle emissions.
Today, air pollution is one of the biggest challenges facing European cities. As part of the Horizon 2020 research project CARES (City Air Remote Emission...
Over the next three years, researchers from the Vrije Universiteit Brussel, University of Cambridge, École Supérieure de Physique et de Chimie Industrielles de la ville de Paris (ESPCI-Paris) and Empa will be working together with the Dutch Polymer manufacturer SupraPolix on the next generation of robots: (soft) robots that ‘feel pain’ and heal themselves. The partners can count on 3 million Euro in support from the European Commission.
Soon robots will not only be found in factories and laboratories, but will be assisting us in our immediate environment. They will help us in the household, to...
Scientists at the University of Leeds have created a new form of gold which is just two atoms thick - the thinnest unsupported gold ever created.
The researchers measured the thickness of the gold to be 0.47 nanometres - that is one million times thinner than a human finger nail. The material is regarded...
