Knew the concept but fumbled the delivery a bit.
Start with a clear, concise definition of zero trust as a security model that assumes no implicit trust and verifies every access request. Then, connect it to system design principles by explaining how it influences architecture decisions, such as micro-segmentation and continuous authentication. Finally, discuss trade-offs like increased complexity and latency, and how to mitigate them.
Pro tip: Relate zero trust to Amazon's leadership principles, such as 'Customer Obsession' (protecting customer data) and 'Insist on the Highest Standards' (security), to show cultural alignment. Also, mention that zero trust is not a product but a mindset shift, demonstrating maturity.
Provide a clear definition: a security model based on 'never trust, always verify,' assuming no implicit trust regardless of network location.
Outline key principles: least privilege access, micro-segmentation, continuous verification, and assume breach.
Describe how zero trust impacts architecture: identity-based access, encryption in transit and at rest, and monitoring/analytics for anomaly detection.
Address challenges: increased complexity, potential latency, and operational overhead, and how to balance security with performance.
Give concrete examples, such as implementing zero trust in a microservices environment or using AWS services like IAM and VPC.
