Network Infrastructure
Jason Garbis, Jerry W. Chapman · Apress eBooks · 2021
Networks, and the hardware and software infrastructures that make them up, are clearly going to be impacted by an organization’s move to Zero Trust. In fact, a large part of the strength and value that Zero Trust brings is its ability to enforce identity and context-aware policies at a network level, bridging these normally separate worlds. As a result, enterprise network infrastructure, operations, and potentially network topology will be affected by a shift to Zero Trust. Security and network architects need to be aware of this, and be able to plan for these changes. Few enterprises will be starting from a completely blank sheet of paper, and security architects planning for Zero Trust need to collaborate with their IT counterparts to understand their current environment. Existing infrastructure components must inform and influence an enterprise’s Zero Trust architecture and requirements while at the same time not imposing too many constraints. That is, networks and their teams, operations, and processes will be required to change as a result of adopting Zero Trust. These changes must be embraced, rather than fought. We know, this is easier said than done, and sometimes changes are more difficult culturally than technically.
