They include collabThese technologies have been used to develop low orative engineering, high-throughput computing cost high performance computing systems, such (large-scale simulation and parameter studies), as clusters, to resolve resource intensive problems remote software access, data-intensive computing, in a number of application domains. In the scien- and on-demand computing. tific pitch the availability of powerful computing resources has allowed scientists to broaden their simulations and experiments to take into account more parameters than ever before. Fast networks have made it possible to share data from instruments and results of experiments with collaborators around the globe almost instantaneously. Recently, research bodies have begun to launch ruthless programs that facilitate creation of such collaborations to tackle large scale scientific problems.

GRID COMPUTING

The concept of grid computing is gaining popular-

As a consequence of the large collaborations and

the increased computational power, the data generated and analyzed within eScience programs are both enormous and intrinsically distributed. Therefore, the challenges of such environments resolve around data managing its access, distribution, processing and storage. These challenges thus motivate creation of a computational infrastructure by coupling wide area distributed resources such as databases, storage servers, high speed networks, supercomputers and clusters for solving large scale problems leading to Grid computing. Grid is a type of parallel and distributed system that enables the aggregation, sharing and selection of geographically distributed autonomous resources dynamically at runtime depending on their availability, capability, performance, cost and users quality of service requirements.

A world wide Grid computing environment The development of the Grid infrastructure, both
hardware and software, has become the focus of large community of researchers and developers in both academia and industry. The major problems being addressed by Grid developments are the social problems involved in collaborative research:

Improving distributed management whilst retaining full control over locally managed resources. Improving the availability of data and identifying problems and solutions to data access patterns. Providing researchers with a uniform user friendly environment that enables access to a wider range of physically distributed facilities improving productivity.

Grid environments involve services such as security, information, directory, execution management, application development, resource allocation, aggregation and scheduling.

SECURITY TRENDS
and firewalls. They should have an encryption solution so as to help prevent the compromise of data in the event of the loss of a device. Appliances that include intrusion prevention and detection as well as other technologies, such as network access control, antispam, antivirus, and other security features, can help a business with limited resources to more comprehensively protect their environment. Also helpful is hiring a qualified security company that can audit the business and point out security exposure areas, as well as Thasnim K M train employees in how to use tools more effectively. No matter how great the tool is, if you dont know how S8 IT 2011 to use it, then its value is dramatically decreased.
KEY POINTS
Data loss prevention technologies are being used more often, providing stronger protection for enterprises. Specific policies for application and device usage are on the rise and help to address security issues that crop up when the line between personal and professional gets blurred. Companies are now leaning toward a layered, centralized approach with multiple security points within the network instead of just around the network.

Just as threats are ever-evolving, so are security tech-

nologies and strategies to combat them. Enterprises face new foes every day. Here we are dealing with the two main aspects of security- Central security which deals with security concerns in organizations and Identity Theft which is one of the fastest growing white collar crimes of the 21st Century.

CENTRAL SECURITY Now a days, more enterprises

are looking toward layered, centralized security with multiple protection points within a network, rather than simply trying to protect a network parameter. Because of the increased use of virtualization, clouds, and online applications, simply surrounding a network with security measures isnt enough anymore. A network now has to be somewhat porous for business efficiency, which means that enterprises are looking at ways to implement security at numerous levels. According to network security firm Fortinet, theres increased focus on preventing infections from cross-pollinating between virtual machines. IT managers are also taking a hard look at cloud-based services, which can open enterprises to risks and vulnerabilities as data is shuttled through multiple networks.

TOP PROTECTION TIPS FOR IDENTITY THEFT Identity theft has been substantially increasing day-

by-day. Its a MUST to know how to protect ourselves from identity theft, so that we dont fall prey to identity thieves.

Protection from Phishing: DO NOT click on links

which you receive via unsolicited emails

DO NOT carry your Social Security card in your

wallet (if you are robbed, thieves might misuse them)

DO NOT share your personal / confidential details Install an Computer Security Software and keep it
updated.

such as bank login and password over chat / instant messengers.

Technologies for data loss prevention and risk miti-

gation are cropping up more frequently for cloud environments, with some companies offering remote management, better software patching, or cloud- specific security assessments.Security technology and tactics may evolve slightly as threats emerge, but by staying on top of the trends and putting solid policies in place, data center managers can have a better chance of foiling the bad guys.

DO NOT visit untrusted websites and download any Always check if the net banking site you visit starts

WASHING MACHINE THAT DOESNT NEED WATER

Anu Thomas,S6 IT 2011

A washing machine that cuts water usage by 90% is

due to hit American shores next year.

The beads are added to the wash along with as little

as a cup of water and a drop of detergent. After the water dissolves the stains, the beads, which become absorbent under humid conditions, soak up the water along with the dirt. The dirt is not just attracted to the surface, but is absorbed into the center of the beads.

The beads are removed automatically within the ma-

chine at the end of the load so theres no need for the user to worry about separating the beads themselves. They also dont require cleaning and can last for about 100 loads or laundry, or about six months of average family usage.

Since the Xeros doesnt require a rinse or spin cycle

the it uses just 2% of the energy of conventional washing machines, cutting CO2 emissions on top of the water savings. The energy savings are further enhanced by the fact that the clothes come out nearly dry, meaning no power-hungry clothes dryer is required. Xeros claims that, taking all these factors into account, its machine achieves a 40% reduction in carbon emis-

Samsung claims worlds first DDR4 memory

chips New generation of PC memory could cut power use, increase speed Samsung has announced that it has created the Worlds first DDR4 DRAM. Samsungs new 30-nanometer-process memory modules are said to run at more than twice the speed of current DDR3 modules, and will also use less power. Samsung says that typical DDR3 memory modules available today use around 1.5V of electrical current, whereas its new DDR4 modules will use just 1.2V. Data transfer speeds on the new DDR4 module can reach 2.133Gbps, according to the company, but it could eventually reach higher speeds of up to 4Gbps.
