Zero trust
An architecture where no user, device, or request is trusted by default. every request is authenticated and authorized regardless of origin. Replaces the older 'castle-and-moat' model where inside-the-network implied trust.
How this shows up at NCAE
The competition image trusts nothing by default. every cron, SSH key, and service access should be justified. Even your own teammates' IPs shouldn't be implicitly trusted on services that don't need it.
