Zero Trust Architecture

Introduction

Imagine a high-security building where passing the security guard at the front door doesn't give you free reign to wander into every office. Instead, you need to swipe your badge at every single door, elevator, and file cabinet you encounter. This is the essence of Zero Trust Architecture. In the digital world, it means that no user or application is trusted by default, even if they are already inside the network. If you are looking to understand the basics of ZTA without getting lost in jargon, you’ve come to the right place. Let’s explore how this security model works and why it’s the future of cyber-security. 

Zero Trust checks for identity every time.

Main pillars of Zero Trust :-

• Identity and Access Management (IAM)
• Device trust 
• Network segmentation
• Application-level access
• Continuous Monitoring
• Least Privilege  

Traditional security model assumes that anything inside corporate model was trusted.This model fails when attacker gets inside the network and finally gets access to all critical systems.

Main rule to follow for implementing ZTA :-

• Never Trust, Always verify
• Least Privilege, Minimum access
• Monitor continously 

Implementation :

Implementing Zero Trust is a continuous journey and it cannot be done overnight.

1. Identify critical assets to protect.
2. Understand how data flows within the network.
3. Implement micro network across critical data.
4. Create Zero Trust Policy and define who can access what.
5. Continuous monitoring of logs traffic
