Tuesday, March 12, 2013

As my career in security response has grown over the years, I am often reminded of the words of Italian author Giuseppe Tomasi Di Lampedusa, who stated, “If we want everything to remain as it is, it will be necessary for everything to change.” There are some things that we wish to stay the same.

Windows typically discovers USB devices when they are inserted or when they change power sources (if they switch from plugged-in power to being powered off of the USB connection itself).
