Apa itu Network segmentation, zero-trust architecture?

Dikenal juga sebagai: network segmentation · zero-trust architecture

Definition 29.7 Research, Data and Risk Platforms · Bab 29 — Security

Network segmentation divides a firm’s network into zones — trading, research, corporate, the outside — with traffic between zones allowed only on stated paths, so that a compromise in one zone does not reach the others. A zero-trust architecture grants no implicit trust for being inside a network: every request is authenticated and authorised on its own, by identity and device, before a session to a resource is established.

The chapter’s network zones and the only paths allowed between them. The trading zone, which holds the venue keys, talks to venues and sends fills to research; parameters come back only through chapter 16’s reviewed path; nothing from the corporate zone or the internet reaches it directly.
