Zero Trust Architecture = A security model where no user or device is trusted by default, whether inside or outside the network, and access is given only after continuous verification.
Zero Trust = “Never trust, always verify”
🏗️ Core Principles of Zero Trust Architecture
Verify Explicitly – Authenticate and authorize based on user identity, device, location, app, and risk.
Use Least Privilege Access – Give users the minimum required access, with Just-in-Time (JIT) and Just-Enough-Access (JEA).
Assume Breach – Always monitor, log, and segment networks to contain damage if attackers get in.
📌 How Your List Maps to Zero Trust Pillars
- Identity → Strong Identity Control (Entra ID, MFA, PIM)
- Devices → Device Compliance (Intune, Defender for Endpoint)
- Access → Adaptive Conditional Access
- Network → Segmentation & Edge Protection (Azure Firewall, NSGs, WAF)
- Applications → Runtime & App Controls (Defender for Cloud Apps, GitHub Security)
- Data → Data Protection (Purview, Encryption, Priva)
- Monitoring → Continuous Threat Detection (Sentinel, Secure Score)
- Infrastructure → Hardening (Arc, Managed Identities, Private Endpoints)
- APIs → API & Private Connectivity (Defender for APIs, APIM)
- Governance → Telemetry & Compliance (Secure Score, JIT Access, Audit)
Zero Trust is no longer optional—it’s the backbone of modern cloud security.
Microsoft’s security ecosystem (Entra ID, Intune, Sentinel, Defender, Purview, etc.), organizations can build a resilient security posture that protects identity, data, applications, and infrastructure end-to-end.
