Smart Machines v. Hackers: How Cyber Warfare is Escalating (Mar 24, 2017)
There is a gaping hole in the digital defences that companies use to keep out cyber thieves. The hole is the global shortage of skilled staff that keeps security hardware running, analyses threats and kicks out intruders. Currently, the global security industry is lacking about one million trained workers, suggests research by ISC2 - the industry body for security professionals. The deficit looks set to grow to 1.8 million within five years, it believes.

Passwords Suck, but Lip-reading Computers Won't Save Us (Mar 21, 2017)
Read my lips: passwords stink, and you already know all the reasons why. And as part of the quest to replace (or at least strengthen) the act of typing in a traditional password, a computer scientist at Hong Kong Baptist University has proposed using lip movement. The system works by analyzing the lip movement—and even lip shape and texture—of a person speaking a password to make sure he or she is authorized, according to the university. That way, even if the wrong person speaks the right pa...
