Zero Trust Architecture

Zero Trust Architecture (ZTA) is a cybersecurity approach based on one core principle:

"Never trust, always verify."

Traditional security assumed that users or devices inside the corporate network could generally be trusted. Zero Trust removes that assumption. Every user, device, application, and request must be continuously verified, regardless of whether it's inside or outside the network.

Core Principles of Zero Trust
Verify every request – Authenticate and authorize every user and device before granting access.
Least privilege access – Give users only the minimum permissions needed to perform their tasks.
Assume breach – Design security with the expectation that attackers may already have access to part of the environment.
Continuous monitoring – Continuously evaluate user behavior, device health, and network activity instead of relying on a one-time login.
Microsegmentation – Divide networks into smaller segments so attackers cannot move freely if they gain access.
