What is zero trust security?

S
Situation
Traditional perimeter security fails against modern threats. Zero trust addresses this.
T
Task
Explain the zero trust model and its core principles.
A
Action
Zero trust: never trust, always verify. Core tenets: Verify explicitly (authenticate every request), Use least privilege (JIT/JEA access), Assume breach (minimize blast radius, segment). Implementation: micro-segmentation, identity-based access, continuous validation, encryption everywhere, extensive logging. Frameworks: NIST SP 800-207, Google BeyondCorp, Microsoft Zero Trust.
R
Result
Organizations adopting zero trust report 50% fewer breaches. This is a leadership-level concept that shows strategic security thinking beyond just technical controls.
