Microsoft Entra Security Groups

Microsoft Entra Security Groups are used to manage access to resources for multiple users at once. Instead of assigning permissions individually, administrators can assign access to a group and add users to that group. This simplifies access management and improves security by ensuring consistent permission assignments.

What are Microsoft Entra Security Groups?

Microsoft Entra Security Groups are collections of users used to assign permissions to resources such as applications, SharePoint sites, and Azure services. When permissions are assigned to a security group, all members of the group automatically receive the same access.

How Security Groups Work

Typical workflow:

1. Create a security group
2. Add users to the group
3. Assign permissions to the group
4. Users inherit access automatically

This reduces the need to manage permissions for each user individually.

Key Features of Microsoft Entra Security Groups

Security Groups vs Microsoft 365 Groups

Feature	Security Groups	Microsoft 365 Groups
Purpose	Access management	Collaboration
Email & Mailbox	❌	✔
Teams Integration	❌	✔

Security groups are primarily used for permission control, while Microsoft 365 groups are used for team collaboration.

When to Use Security Groups

Use security groups when:

• You need to assign access to applications or resources
• You want to manage permissions centrally
• You need dynamic membership based on user attributes
• You want to simplify access management at scale

Conclusion

Microsoft Entra Security Groups provide a scalable and efficient way to manage access permissions across users and resources.

By using security groups, administrators can simplify identity management, reduce manual effort, and ensure consistent access control across the organization.
