Zero-trust security is an approach to cybersecurity that assumes no user or device should be trusted by default, even if they are within the network perimeter. Instead, access to resources and data is strictly controlled and continuously verified, regardless of location or device. This has several implications for data analytics in zero-trust security environments. The members of the MESA Analytics Matter Working Group will discuss the implications of the need for more data in the face of greater security and constraints on data access. Stephen Jackiw joins us with his perspective from the cyber-security world.
