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.)

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
