In today's digital landscape, security is paramount, especially within cloud environments like Azure. The critical importance of safeguarding data, applications, and infrastructure against ever-evolving threats cannot be stressed enough. To ensure that resources are valid, secure and available, customers must have strong security measures in place.

This blog explores the significance of security in Azure environments and provides an overview of native as well as third-party security tools available to improve an organization’s Azure security stance.

Top tools for Azure security

Azure offers a wide range of security tools, addressing key areas such as identity and access management (IAM), data protection, network and application security, compliance management, and threat detection. 

While data protection techniques encrypt sensitive data and implement access rules, IAM helps implement the principle of least privilege. Meanwhile, network and application security solutions help defend against dangers like DDoS attacks and intrusion detection, and threat detection solutions leverage advanced analytics to quickly identify and address security problems. Lastly, compliance management tools simplify regulatory adherence. 

We’ll be reviewing some of the tools that address these key areas, offering insights into their functionalities and advantages.

Identity and access management (IAM)

Microsoft Entra ID (formerly Azure Active Directory) acts as a centralized IAM solution for user identities, ensuring all access requests go through a unified system in Azure. It offers the following features and benefits for securing workloads in Azure.

Fine-grained access control 

The identities in Microsoft Entra ID can be used to implement fine-grained access control via role-based access control (RBAC). Following the principle of least privilege, users can restrict access to resources with both built-in or custom roles. 

Single sign-on 

If you’re already using other identity management services, you can integrate these with Microsoft Entra ID using federation, linked sign-on, or passwords. The federation options include OpenID Connect (OIDC), SAML, and OAuth, ensuring a seamless experience for users.
