The Department of Electronics of the University of Granada (Universidad de Granada [http://www.ugr.es])has published in the international journal Computer Networks a paper suggesting a series of techniques to model the normal traffic in the Internet and identify hackings based on anomalies detection.
Specifically, the techniques have been focused on the protocol HTTP “with which more than 70% of the network activity works, such as the main trade services of the web”, Juan Manuel Estévez Tapiador, author of the paper together with Pedro García Teodoro and Jesús Díaz Verdejo, points out.
The work has developed in two phases: statistical analysis of normal and hostile traffic and proposal of a new approach to detect attacks in HTTP traffic. The first stage is useful to define statistically, by means iof techniques such as Markov chains, a notion of the normal behaviour of a network and the later detection of anomalous happenings when operating. “In general, the concept of attack is not well defined unless we start from a security policy, established by the system administrator to keep the control of the network”, Estévez says.
The idea is to design warnings as counter-measures to tackle the threats of the Internet. These works mean an improvement of present IDS. They are softwares (computer programs) capable of monitoring everything happening in the Internet, such as users' requests addressed to web servers. Definitely, everything that enters or leaves the Internet, identifying if it keeps with the normal activity or there is somebody trying to violate the security system.
The Department of Electronics of the UGR has proposed a general methodology to build detectors, including aspects like where they must be placed in the Internet and what kind of information must be supervised. The article starts from a theoretical review of previous contributions carried out by a research group of the University of California on security in the Internet and has opened a door to design new detection techniques, the topic of Estévez Tapiador's doctoral thesis, read in 2004.

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.
Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

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...
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.
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...
