Zero Trust

Zero Trust Model 🔒

"Never trust, always verify." The Zero Trust Model assumes that threats exist inside and outside the network. Every access request must be verified, authorized, and continuously monitored—regardless of location or device.

---

🔹 Core Principles

✅ Verify Every Access Request – No implicit trust, even for internal users.
✅ Least Privilege Access – Grant only the minimum required permissions.
✅ Micro-Segmentation – Divide networks to prevent lateral movement.
✅ Continuous Monitoring – Detect unusual behavior and revoke access if needed.
✅ Multi-Factor Authentication (MFA) – Require multiple verification steps.

---

🔹 Real-World Implementations

🔹 MFA for All Users – Require extra verification for logins.
🔹 Role-Based Access Control (RBAC) – Limit access based on job roles.
🔹 Device Trust Verification – Allow only approved devices to connect.
🔹 Micro-Segmentation in Kubernetes – Restrict pod-to-pod communication.
🔹 Cloud Security (AWS/Azure) – Use Identity and Access Management (IAM) with Zero Trust policies.

🔹 Benefits

✅ Prevents Unauthorized Access – Stops attackers from exploiting trust.
✅ Reduces Attack Surface – Restricts access across the network.
✅ Mitigates Insider Threats – No one gets access by default.
✅ Enhances Compliance – Meets GDPR, HIPAA, and ISO 27001 standards.

🔹 Implementation in Cloud & DevOps

🔹 Use IAM roles & RBAC for granular access control.
🔹 Enable network policies in Kubernetes for micro-segmentation.
🔹 Deploy Identity Providers (IdP) like Okta, Azure AD, or AWS IAM.
🔹 Enforce endpoint security before allowing access to cloud resources.
