Understanding Zero Trust on Linux

Zero Trust Architecture

NIST SP 800-207 defines Zero Trust as a security model that eliminates implicit trust and continuously validates every stage of a digital interaction.

Core Principles

1. Verify explicitly: Always authenticate and authorize based on all available data points

2. Least privilege access: Limit user access with Just-In-Time and Just-Enough-Access

3. Assume breach: Segment access, verify end-to-end encryption, and use analytics to detect threats

Implementation on Linux

LIBUX implements Zero Trust through integrated identity, device attestation, and network policy enforcement.
