The Advanced Persistent Threat (APT) is extremely dangerous to the national and economic security. To address this reality in the 21st century, the one-dimensional protection strategy focused solely on perimeter-based defenses must be transitioned to a new multidimensional, defense-in-depth protection strategy that includes three, mutually supportive and reinforcing concepts: (1) penetration resistant architectures; (2) damage limiting operations; and (3) system designs that support cyber resiliency and survivability.A promising concept that can support a multidimensional protection strategy is Zero Trust Architectures.Attend this session to learn more about:Multidimensional protection strategiesNIST's view of zero trustThe role of zero trust in this new defensive strategy
