Zero Trust Architecture

Zero Trust Architecture (ZTA) is a cybersecurity framework that assumes no implicit trust for any user, device, or network component, regardless of location. It enforces strict identity verification, least-privilege access, and continuous monitoring for all resources. This approach shifts security from perimeter-based defenses to a model where every access request is treated as potentially hostile.

Also known as: ZTA, Zero Trust, Zero Trust Model, Zero Trust Security, Zero Trust Framework

Why learn Zero Trust Architecture?

Developers should learn Zero Trust Architecture to build secure applications in modern environments like cloud, remote work, and IoT, where traditional network perimeters are ineffective. It's essential for compliance with regulations (e.g., GDPR, HIPAA) and protecting sensitive data from insider threats and external breaches. Use cases include securing microservices, APIs, and hybrid cloud deployments.
