Example Concept: Zero-trust architecture involves segmenting the network, enforcing strict identity verification, and continuously monitoring for threats. Start by identifying critical assets and data flows, then implement micro-segmentation to isolate these assets. Use multi-factor authentication (MFA) and least privilege access controls to ensure that users and devices are verified before accessing resources. Continuously monitor network traffic and user behavior for anomalies using a Security Information and Event Management (SIEM) system to detect and respond to potential threats.
