From Alan Turing’s breakthrough in computing mathematics, we Tardis to the 1970s when the next great advancements were made.

This decade – during which the first of Generation X children were born – cryptography’s centre of gravity shifted from mechanical rotors and the hard lessons of WWII, to number theory and algebra amplified by silicon’s relentless gains. This cohort would become the ‘bridge generation’ that transitioned the world from analogue to digital: the first to have PCs in homes and schools during their youth, pioneers of the technology that defines the modern world.

But we can’t muse on these middle-aged people, because first there is the question of securing those nascent PCs. Early network break-ins, growing databases and political scandals made one fact hard to ignore: information was becoming valuable, and vulnerable.

And so, we needed to lock down our desktop machines.
