Air gapped systems leak secrets in new ways

Some critical systems aren’t exposed to the public internet and sit, apparently safely, in an isolated environment, air gapped from the rest of the world by a lack of internet connectivity. The integrity of the air gap is only maintained when the means of data transport in and out of the environment are equally subject

Curve tracers

Curve tracing is a classic way to learn more about many electronic components. Curve tracing is essentially a means of making a graph of current (I) versus voltage (V) called an I-V curve, to display the basic characteristics of an electronic device. I-V curves of the components are helpful in understanding their limitations and nonlinear
