Implementing Zero Trust Security: A Practical Guide

## What is Zero Trust? Zero Trust is a security framework that requires all users, whether inside or outside the organization's network, to be authenticated, authorized, and continuously validated. ## Core Principles 1. **Never Trust, Always Verify** - Every request must be authenticated 2. **Least Privilege Access** - Users only get access to what they need 3. **Assume Breach** - Design systems as if attackers are already inside ## Implementation Steps ### Step 1: Identity Verification Implement strong identity verification for all users and services: - Multi-factor authentication (MFA) - Service mesh for service-to-service communication - Short-lived credentials ### Step 2: Micro-Segmentation Break your network into small, isolated segments: - Network policies in Kubernetes - VPC security groups - Application-level firewalls ## Conclusion Zero Trust isn't a product—it's a philosophy. Start small, iterate often, and build security into your culture.
