Zero Trust Architecture

About

Zero Trust Architecture (ZTA) is a security strategy that assumes no entity—user, device, or application—should be trusted by default. It emphasizes continuous verification and access controls to prevent unauthorized access. This approach contrasts with traditional security models that rely on a defined network perimeter, where entities inside the network are often trusted implicitly. Zero Trust requires real-time risk assessments and least-privileged access to ensure that only verified and authorized entities can access resources. Key principles of Zero Trust include continuous verification, limiting the blast radius in case of a breach, and applying context-aware policies. It involves multifactor authentication, microsegmentation, and environment-agnostic security to protect resources across diverse environments, such as cloud and hybrid networks. Zero Trust enhances security by eliminating implicit trust and focusing on explicit identity-based trust, making it particularly effective in modern digital landscapes with remote work and cloud services.
