Lior Frenkel is the CEO and co-founder of Waterfall Security Solutions, a provider of unidirectional security gateways, stronger-than-firewalls perimeter security solutions for industrial control networks and critical infrastructures.
In this interview he talks about the vulnerability of global critical networks, challenges related to safeguarding such security architectures from zero-day attacks, ICS security in the future, and much more.
Based on your experience, how vulnerable are global critical networks?
There are a lot of big industrial sites in the world and far more small sites. In my experience, many of the larger sites and some of the smaller ones are reasonably well defended against the simplest attacks, like common malware and stolen passwords. But the opposite is true as well – some of the big sites and a huge number of small ones are poorly defended.
