Zero Trust Architecture
Noun · Security & Infosec
Definitions
A security model that treats every access request as untrusted until identity, device, and context are verified. It shows up in application security, identity, infrastructure, or incident response work depending on the environment. Teams use the concept to prevent abuse, detect adversary activity earlier, or define stronger control boundaries during engineering, testing, and operations.
In plain English: Zero Trust Architecture is the practical security idea behind a control, weakness, or safeguard. It matters because it changes how attackers succeed or defenders reduce risk.
Example: "During the review, the team focused on Zero Trust Architecture after telemetry and testing showed it was the fastest way to reduce exposure, tighten controls, and close a realistic attack path before the next production release."
