The UGR analyses the modelling of the behaviour of the communication networks in hacking detection

09.01.2007
Hackers' activity. The existence of numerous viruses and their incessant appearance. Global distrust in electronic trade. There are a lot of reasons to deal seriosly with the problem of security in the Internet.

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.

Doctoral thesis

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.

Im Focus: It’s All in the Mix: Jülich Researchers are Developing Fast-Charging Solid-State Batteries

There are currently great hopes for solid-state batteries. They contain no liquid parts that could leak or catch fire. For this reason, they do not require cooling and are considered to be much safer, more reliable, and longer lasting than traditional lithium-ion batteries. Jülich scientists have now introduced a new concept that allows currents up to ten times greater during charging and discharging than previously described in the literature. The improvement was achieved by a “clever” choice of materials with a focus on consistently good compatibility. All components were made from phosphate compounds, which are well matched both chemically and mechanically.

The low current is considered one of the biggest hurdles in the development of solid-state batteries. It is the reason why the batteries take a relatively long...

A new study sheds light on how ultralow frequency radio waves and plasmas interact

Scientists at the University of California, Los Angeles present new research on a curious cosmic phenomenon known as "whistlers" -- very low frequency packets...

Im Focus: New interactive machine learning tool makes car designs more aerodynamic

Scientists develop first tool to use machine learning methods to compute flow around interactively designable 3D objects. Tool will be presented at this year’s prestigious SIGGRAPH conference.

When engineers or designers want to test the aerodynamic properties of the newly designed shape of a car, airplane, or other object, they would normally model...

Im Focus: Robots as 'pump attendants': TU Graz develops robot-controlled rapid charging system for e-vehicles

Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.

Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....
