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.

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
