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.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.
How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...
Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.
It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
