Computer Security Team Defining the Expanding World of Cloud Computing

25.05.2009
A working definition for cloud computing—a new computer technique with potential for achieving significant cost savings and information technology agility—has been released by a team of computer security experts at the National Institute of Standards and Technology (NIST).

Since the federal government is considering cloud computing as a component of its new technology infrastructure, it is NIST’s role to evaluate it and then promote its effective and secure use within government and industry by providing technical guidance and developing standards.

The working definition of cloud computing described by NIST is “a pay-per-use model for enabling available, convenient and on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.” The draft working definition also describes five key characteristics, three delivery models and four deployment models.

The NIST cloud computing research team is studying cloud architectures, security and deployment strategies for the federal government. But its first task was to collaborate with industry and government to develop a working definition of cloud computing that will serve as a foundation for its research. The term “cloud computing” comes from the field’s standard use of drawing the Internet as a cloud in diagrams.

Security is always a concern with any new computer approach, and this one is no different. According to cloud research team leader Peter Mell, “Cloud computing has both security advantages and disadvantages. The cloud computing model inherently promotes availability of services through its distributed architecture model. However, this same model presents data confidentiality and integrity challenges by pooling hardware resources for use by multiple parties.”

The full working draft definition is available at http://csrc.nist.gov/groups/SNS/cloud-computing/index.html. Comments on the definition can be sent to cloud@nist.gov.

Im Focus: Scientists channel graphene to understand filtration and ion transport into cells

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.

To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...

Im Focus: Towards data storage at the single molecule level

The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.

Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
