What Is Zero Trust Security?
By Karthick Selvam · Published
Zero trust is a security approach that assumes no user or device is trusted by default, even inside the network.
In this article
Core principles
Verify explicitly, use least-privilege access, and assume breach.
In practice
Strong identity and MFA, device health checks, micro-segmentation, continuous monitoring and access decisions per request.
Why it emerged
Cloud services and remote work weakened the idea of a trusted internal network.
Getting started
Begin with identity: MFA everywhere, conditional access and removing standing admin privileges.
Frequently asked questions
Is zero trust a product?
No. It is an architecture and set of principles implemented with many tools.
