Introduction
Security is the most critical consideration in any cloud deployment. Microsoft Azure provides a comprehensive suite of security services and tools, but security is not automatic — it must be deliberately designed, configured, and maintained. This blog covers the Azure security best practices that Ozy Solutions recommends for building a Zero Trust cloud environment.
What Is Zero Trust and Why It Matters for Azure
Zero Trust is a security philosophy based on the principle of never trust, always verify. Traditional perimeter-based security assumed that everything inside the network could be trusted. Zero Trust assumes breach — every access request is treated as potentially hostile regardless of where it originates. This approach is particularly well-suited to cloud environments where the traditional network perimeter no longer exists.
Identity as the New Security Perimeter
In a Zero Trust Azure environment, identity is the primary security control. Microsoft Entra ID (formerly Azure AD) provides the identity platform. Every access request must be authenticated and authorized before it is granted. Multi-factor authentication should be required for all users, especially administrators. Conditional access policies evaluate device compliance, user risk, sign-in risk, and location before granting access to applications.
Network Security in Azure
Network segmentation and micro-segmentation limit the blast radius of any security incident. Azure Virtual Networks provide isolation boundaries. Network Security Groups and Azure Firewall control traffic flows between network segments. Azure DDoS Protection defends against volumetric attacks. Azure Private Endpoints eliminate public internet exposure for Azure PaaS services, one of the most impactful security improvements organizations can make.
Data Protection and Encryption
All data in Azure should be encrypted at rest and in transit. Azure Storage Service Encryption protects data at rest using Microsoft-managed or customer-managed keys stored in Azure Key Vault. Azure SQL Database transparent data encryption protects database files. All Azure services use TLS for data in transit. Customer-managed keys in Azure Key Vault provide the highest level of control over encryption.
