The Payment Card Industry Data Security Standard (PCI DSS) is a set of industry regulations imposed by the major credit card companies to ensure the safety, security, and integrity of cardholder data. Any business that processes, stores, and transmits cardholder account data must comply with this complex new standard, and must be able to demonstrate that compliance through automated and manual audits of their systems. This white paper looks at the key challenges and requirements of PCI DSS as it relates to Microsoft Windows and Active Directory, and shows you how a third-party software solution can help with PCI compliance.

There are many compelling reasons for virtualizing Windows and Linux applications. Virtualization improves server utilization by allowing you to run multiple workloads on a single physical server. It reduces the number of physical servers you have to maintain, while allowing you to use less physical space and power while still improving scalability. All of these capabilities translate directly into lower costs, less complexity, and greater flexibility in your mixed IT environment.

Ultra-low-power ZigBee-based wireless mesh networks, powered by a variety of energy-harvesting technologies, make it possible to create the first truly wireless and battery-less sense and control networks for regulating energy consumption in domestic and industrial uses.
Homes, offices and factories waste energy on lighting, heating and air conditioning. With the help of light- and temperature-sensor network technologies, energy conservation processes such as turning off lights and adjusting temperature now can be automated, reducing costs.
Until now, wires and cables for power and connectivity have limited the widespread adoption of sensor networks by making them difficult and expensive to install and maintain. Battery-powered wireless networks can simplify installation, but their high power consumption and the corresponding need for regular battery replacement renders this option costly to maintain. Nobody wants to replace hundreds or thousands of window sensor batteries in a large building on a regular basis.
The promise of wireless sensor networks can only be fully realized when the wiring for both data communications and power supply is eliminated.
Besides reducing cost and maintenance requirements, doing away with batteries eliminates the waste and headaches associated with disposing of and recycling batteries. This environmentally friendly approach also extends the reach of sensor technology to distant and inhospitable climates and regions.
Consider, for example, a network of sensors for leak detection on a remote oil pipeline. Accommodating thousands of standard wired sensors spread out over hundreds of miles of pipeline is financially challenging, even with the enormous environmental risk associated with oil leaks. Alternatively, a wireless sensor network equipped with energy harvesters is fairly inexpensive and straightforward to install. No batteries, no power lines, no network cables.
Two of the most significant requirements for widespread adoption of wireless sense and control products are ease of use and reliability. Battery-free technology helps address these requirements for the units themselves, but the reliability of the communications chain that interconnects the sensors is just as critical.
