In fact the root system of any tree is twenty times the size of the visible canopy. Forget the forest versus trees debate. The culture we create lives and thrives underground. In this session participants will learn to apply Systems Security Engineering to their business in order to create an Advanced Persistent Threat network to match the millions of miles of mycelium that protect the Wood Wide Web of our forest floors.
