Understanding Zero Trust Architecture: Enhancing Security with ‘Never Trust, Always Verify’
Zero Trust Architecture (ZTA) is a cybersecurity model based on the principle of “never trust, always verify.” It ensures that every user, device, and data packet is authenticated and authorized before accessing network resources. Key principles include explicit verification, least privilege access, micro-segmentation, continuous monitoring, and encryption. Implementing ZTA can enhance security, reduce data breach risks, and improve access control, though it requires significant infrastructure changes and user education. As cyber threats evolve, integrating AI and machine learning with ZTA will be crucial in securing cloud computing, edge computing, and IoT environments.
