Azure identity and access management considerations

Most architectures have shared services that are hosted and accessed across networks. Those services share common infrastructure and users need to access resources and data from anywhere. For such architectures, a common way to secure resources is to use network controls. However, that isn't enough.

Provide security assurance through identity management: the process of authenticating and authorizing security principals. Use identity management services to authenticate and grant permission to users, partners, customers, applications, services, and other entities.

Checklist

How are you managing the identity for your workload?


  • Define clear lines of responsibility and separation of duties for each function. Restrict access based on a need-to-know basis and least privilege security principles.
  • Assign permissions to users, groups, and applications at a certain scope through Azure RBAC. Use built-in roles when possible.
  • Prevent deletion or modification of a resource, resource group, or subscription through management locks.
  • Use Managed Identities to access resources in Azure.
  • Support a single enterprise directory. Keep the cloud and on-premises directories synchronized, except for critical-impact accounts.
  • Set up Azure AD Conditional Access. Enforce and measure key security attributes when authenticating all users, especially for critical-impact accounts.
  • Have a separate identity source for non-employees.
  • Preferably use passwordless methods or opt for modern password methods.
  • Block legacy protocols and authentication methods.

Monitor the communication between segments. Use data to identify anomalies, set alerts, or block traffic to mitigate the risk of attackers crossing segmentation boundaries.
