Seeking to tighten the Net against attack

11.07.2006
As more users switch to broadband internet access, security providers are playing a frantic game of ‘catch-up’ to secure networks against the many threats. While new menaces are always just around the corner, one project believes it may have part of an answer to one of the most common and destructive forms of intrusion.

The IST-funded DIADEM Firewall project has developed a novel and comprehensive security solution for secure broadband services, focusing on denial of service attack and mitigation, thanks to collaboration between a consortium of interested stakeholders from France Telecom, Polish Telecom, IBM Research, Imperial College London, University of Tübingen, Groupe des Ecoles des Télécommunications and Jozef Stefan Institute.

A distributed denial-of-service attack (or DDoS attack) attacks computer systems or networks and usually results in a loss of service to users, typically the loss of network connectivity and services by consuming the bandwidth of the victim network or overloading the computational resources of the system. The attack typically uses thousands of compromised home and business computers (or zombies) to bring down corporate systems, often as part of a blackmail attempt.

How big a problem is it? Well, DDoS attacks affected over 13 per cent of businesses in the United Kingdom at a cost of more than £558m in 2004 alone, according to the UK’s National Hi-Tech Crime Unit (NHTCU). The malicious data traffic can also significantly degrade the broadband experience for residential internet users, and impose dramatic network and customer support costs on broadband service providers. With broadband penetration projected to increase significantly in the coming years, that figure is likely to increase exponentially.

“There is no doubt that denial-of-service attacks are a growing issue as more and more services, such as online games, IP telephony, television over IP and e-shopping are provided to broadband users through the internet,” explains Yannick Carlinet, project coordinator of DIADEM Firewall. “It is a crucial and vulnerable aspect of broadband security and will become even more so in the future as more users move over to broadband connections,” he adds.

To strike back at the broadband bandits, the DIADEM Firewall partners opted to develop a distributed detection and reaction system located in the network and managed by the network operator. As Carlinet notes, this is already a radical move away from the current approach where end users are responsible for their own online security.

“The current security paradigm requires all end-users to organise and manage the security of their own terminals. This has many shortcomings and the failure of such an approach has been demonstrated too often in recent times for it to be considered a viable solution,” he says.

The DIADEM Firewall solution, by contrast, puts the focus back on the network provider. “Our overall goal was to develop and deploy innovative network components that enable service providers to offer to their customers secure broadband services in an effective and cost-efficient way,” says Carlinet.

“Functional and performance tests are taking place right now and we are optimistic that we’ll be able to show substantial progress over the state-of-art intrusion and prevention systems,” he says.

Indeed, technical issues are the least of the worries facing DIADEM Firewall as the project seeks to convince the key network players that they need to be proactive in ensuring the security of their broadband services.

“I think the main difficulties that need to be overcome now are strategic,” says Carlinet. “We need business units of Internet Service Providers (ISPs) and network operators to take account of the paradigm shift in security matters that is currently taking place, such as the transition from uncoordinated end-terminal security management to distributed network security policies.”

While operators may be somewhat resistant to the idea of change, they recognise nevertheless the commercial value of DIADEM Firewall solution, adds Carlinet.

“Discussions are ongoing with France Telecom and Polish Telecom business units with regard to commercial exploitation of our solution. We are also in contact with some application-level packet processor manufacturers that are interested in our approach.”

Other follow-ups are also planned to build on the sterling work achieved by the project. “There are a number of collaborative projects that have recently started and there is also the likelihood of future project proposals, for instance to extend the DIADEM solution to cope with internet worms,” concludes Carlinet. “There are also various internal projects by the individual partners and discussions with manufacturers for the implementation of functions designed in the project in commercial products.”

Im Focus: AchemAsia 2019 will take place in Shanghai

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.

Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.

Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.

Im Focus: Sharp images with flexible fibers

An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.

Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...

Im Focus: Water is not the same as water

Water molecules exist in two different forms with almost identical physical properties. For the first time, researchers have succeeded in separating the two forms to show that they can exhibit different chemical reactivities. These results were reported by researchers from the University of Basel and their colleagues in Hamburg in the scientific journal Nature Communications.

From a chemical perspective, water is a molecule in which a single oxygen atom is linked to two hydrogen atoms. It is less well known that water exists in two...
