In recent months, the FBI issued a high-impact cybersecurity warning in response to increasing attacks on government targets. Government officials have warned major cities such hacks are a disturbing trend likely to continue. Purdue University researchers may help stop some of those threats with a tool designed to alert organizations to cyberattacks. The system is called LIDAR – which stands for lifelong, intelligent, diverse, agile and robust. "The name for this architecture for network security really defines its significant attributes," said Aly El Gamal, an assistant professor of electrical and computer engineering in Purdue's College of Engineering.

In today's always connected world, losing power is more than just an annoyance. "The truth is, we rely on electricity much more than we realize," writes Sherry Hewins in her column What Could Happen in a Long-Term Power Outage? "Even if you live'off the grid' as I did for years, you are still living in a world and a society that is deeply dependent upon electricity." It is the "deep dependency" that has power companies moving toward what is called the Smart Grid, a more efficient and reliable power-distribution infrastructure. One reason these capabilities are possible is the use of two-way communications between power-distribution centers and smart equipment (smart meters and smart appliances) downstream. Enhanced communications help more than just the people who make sure electricity keeps flowing.
