To make it easier to measure the security of an information technology product or system, researchers at the National Institute of Standards and Technology (NIST) and the National Security Agency (NSA) have developed a common specification language--Extensible Configuration Checklist Description Format (XCCDF)--for writing security checklists and related documents.
Increasingly, computers and other information technology products are vulnerable to multiple threats including viruses, worms and identity or information theft. One basic, yet effective, security tool is the security configuration checklist--a series of instructions for configuring an information technology (IT) product to a baseline or benchmark level of security. Configuring a system into conformance with a benchmark or other security specification is a time-consuming and very technical task. Automated tools are available to help system administrators determine a systems conformance and recommend corrective measures. However, most of these tools are designed for a particular IT product or system.
XCCDF is an XML-based format that is flexible, vendor-neutral and suited for a wide variety of checklist applications including measuring conformance of an IT system to security benchmarks and generating a record of a benchmark test. (XML is a language--analogous to the HTML codes used to format web pages--that describes information in a standard way to allow computers to exchange information and act on it.)

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
