What is Zero Trust?
Zero Trust is a security framework based on the principle of "never trust, always verify." Unlike traditional perimeter-based security, Zero Trust assumes no user, device, or network should be automatically trusted—even those inside the corporate network.
Core Principles
The three pillars of Zero Trust are: verify explicitly (always authenticate and authorize based on all available data), use least privilege access (limit user access with just-in-time and just-enough-access), and assume breach (minimize blast radius and segment access).
Implementation Roadmap
Start by identifying your protect surface—the critical data, assets, applications, and services (DAAS) that need protection. Map transaction flows, architect your Zero Trust network, create policies, and monitor continuously.
Key Technologies
Zero Trust implementations typically include identity and access management (IAM), multi-factor authentication (MFA), micro-segmentation, endpoint detection and response (EDR), and security information and event management (SIEM).
Measuring Success
Track metrics including reduction in security incidents, time to detect and respond to threats, and user experience impact to measure Zero Trust effectiveness.
