Intelligent programs protect your computer environment

15.10.2008
Scientists from the Universidad Carlos III de Madrid (UC3M) have unveiled a system capable of detecting computer intrusions and automatically deciding the best response.

Intrusion detection systems (IDS) are security tools designed to monitor computer systems for suspicious events. To reduce the risk of intrusion, which is one of the threats to computer security, a team of researchers at UC3M have unveiled a multi-agent system that identifies suspicious events and autonomously determines whether or not any action should be taken. According to Professor Agustin Orfila of the Department of Informatics of the UC3M, both these are desirable features in an IDS.

At present, Spain lags behind in advancing investigations in multi-agent architectures for IDS compared to other countries. According to the investigator, the innovation behind the study is the use of deliberative agents that can adapt to the surroundings they are confronted with, and consider their past success in an independent manner to decide whether or not they should respond when facing a suspect event. This is achieved by using a “quantitative model that weighs the loss that an intrusion would provoke against the cost of taking responsive action”, Professor Orfila indicates. In this way, the IDS multi-agent determines the best system configuration for each scenario and decides if a response is appropriate, quantifying to what extent IDS supports the calculated decision. One of the most common intrusions attacks are the “port scan attack” (searching for open ports), denial-of-service attack, achieving unrestricted access to the target computer and triying to acces a computer remotely.

Farewell to intrusions

According to the National Institute of Standards and Technologies of the United States, “Intrusion detection is the process of detecting unauthorized use of, or attack upon, a computer or network. IDSs are software or hardware systems that detect such misuse.” Professor Orfila adds that an agent should be imparted with capabilities such as reactivity, sociability, self-initiative, adaptation, mobility, with a final result of representing a person. “In this way, the IDS multi-agent architecture allows us to distribute the detection load and better co-ordinate the process, with the consequence of accomplishing a more efficient detection”, explains the professor.

Security administrators would be the ideal users for the system because “it would allow them to quantify the value that the IDS attaches to its decisions and moreover, it would indicate how to adequately tune the IDS to its environment”, states Professor Orfila. Nevertheless, in order to implement its use, he adds, the IDS would have to be adapted to the traffic of the real network, the system would require to be trained for the concrete surroundings and the functionality would have to be evaluated in this real environment.

This study, published in the magazine Computer Communication under the title “Autonomous decision on intrusion detection with trained BDI agents”, has been developed by Agustín Orfila, Javier Carbó and Arturo Ribagorda, of the Grupo de Seguridad de las Tecnologías de la Información y las Comunicaciones and the Grupo de Inteligencia Artificial Aplicada of the Departamento de Informática of the UC3M.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
