Like an episode of "CSI: Computers," a UF researcher has developed a technique that gives digital detectives twice the forensic evidence they now have to catch all kinds of hackers, from curious teenagers to disgruntled employees to agents of foreign governments.
Writing in the current issue of the International Journal of Digital Evidence, UF doctoral student Mark Foster proposes a new and improved method of computer crime solving, called “process forensics.” “If a guy walks into a bank and robs it, leaving footprints behind or his fingerprints on the counter, the forensic analyst would come in and find those traces of what happened,” said Foster. In the same way, process forensics merges two existing types of digital evidence – intrusion-detection and checkpointing technology – to give an investigator the most possible information to crack a case, said Foster, a computer science and engineering student conducting the research for his dissertation with UF professor of computer science Joseph Wilson, who co-wrote the paper. “If you detect the intruder – or even if you’re just suspicious that an intruder’s around – you start creating checkpoints,” Foster said. “And then later, those checkpoints will serve to give us some forensics.”
Checkpoints are essentially periodic snapshots of a running computer program, or process. Programmers use them as a safety backup – if the power goes out while a program is still running, they can return to the most recent checkpoint rather than starting over from the beginning.

AI implications: Engineer's model lays groundwork for machine-learning device

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
