Zero trust
Zero trust is a security model built on the assumption that no device, user, or network segment should be trusted by default, including ones already inside a traditional network perimeter -- every request must be authenticated, authorized, and verified on its own merits, continuously, rather than once at the network's edge. This is a direct response to the failure mode of older "castle and moat" designs, where anything that got past the firewall was then implicitly trusted to reach internal systems. In practice, zero trust shows up as per-request identity verification, least-privilege access scoped narrowly to what's needed, and replacing direct network-level access, like exposing RDP or a VPN to a whole subnet, with brokered, identity-aware connections to individual resources.
