How to create a security group in Microsoft 365?

Security groups in Microsoft 365 are collections of users, devices, or other groups that allow admins to manage permissions and access to resources efficiently. They help admins streamline management by assigning permissions collectively rather than individually. This approach enhances security, simplifies administration, and ensures that policies & settings are applied consistently across multiple users or devices.

Are Security Groups Essential for Organizational Security?

No, but security groups are highly recommended to manage permissions, ensure consistent access rights, and reduce the risk of errors when handling large numbers of users or devices. Follow the steps described below using the Entra admin center or the PowerShell to create security groups in the Azure Active Directory.

Create a Security Group Using Microsoft Entra Admin Center

Log in to the Microsoft Entra admin center and navigate to Identity»Groups»All groups»New group.
By default, Security is selected in the Group type field. Next, enter a name for the group and provide a description.
If you want to assign roles to the security group, switch the Microsoft Entra roles can be assigned to the group toggle to Yes. Once this setting is enabled, the group's eligibility for role assignment becomes permanent and cannot be reverted.
Select the Membership type based on your preference:
- Assigned: This option enables you to manually assign members to the groups.
- Dynamic user: Using this option, you can automatically assign membership based on user attributes, such as department, location, etc.
- Dynamic device: With this option, you can automatically assign membership based on device attributes, such as operating system, device type, etc.
Select the owners for the group by clicking the No owners selected link in the Owners section.
Add members to the security group by selecting the No members selected option in the Members section.
Review your settings and click Create to create the group.

Add a Security Group Using PowerShell

Connect to the Microsoft Graph PowerShell using the cmdlet below.

Connect-MgGraph -Scopes "Group.ReadWrite.All", "GroupMember.ReadWrite.All"

Use the New-MgGroup cmdlet below to create a new security group.

New-MgGroup -DisplayName "<GroupName>" -MailNickname "<MailNickname>" -Description "<GroupDescription>" -SecurityEnabled -MailEnabled:$False

To add members to a group, use the New-MgGroupMember cmdlet with the Group ID and the User ID.

New-MgGroupMember -GroupId "<SecurityGroupID>" -DirectoryObjectId "<UserID>" 
#Make sure to replace <SecurityGroupID> and <UserID> with the appropriate values before executing the command.

Note: You can use the Get-MgUser cmdlet to retrieve the User ID.

Use the New-MgGroupOwner cmdlet to add owners to a specific security group.

New-MgGroupOwner -GroupId  "<SecurityGroupID>" -DirectoryObjectId "<UserID>"

Enhance security group tracking in Microsoft 365 with AdminDroid’s detailed insights, overcoming the limitations of Azure AD audit logs and the need for additional filtration.

By applying a simple filter where GroupType equals SecurityEnabled in the created groups report, you can monitor all security group creations effortlessly.
This allows you to see details such as who created the group, when it was created, the group name, and more, saving you time and effort while maintaining oversight.

Handy Hint: Save your customized view using the 'Save as view' option to quickly access the report without applying filters each time.

How to manage Microsoft 365 licenses and admin roles using security groups?

While Microsoft 365 security groups simplify administrative tasks by centralizing management, they are especially useful for assigning group-based licenses and managing admin roles. These tasks are crucial for various departments such as Sales, Marketing, and IT which often need different Microsoft 365 licenses. This approach not only saves time but also ensures that employees have the necessary resources and permissions, enhancing organizational efficiency.

Assign Licenses for Security Groups via the Microsoft 365 Admin Center

Log in to the Microsoft 365 admin center and navigate to Billing»Licenses to view all available licenses in your organization.
Select the license you want to assign for the security group(s).
In the License details section, locate the Groups tab and choose Assign licenses.
In the flyout pane, search for the respective security groups and add them to assign licenses.
Click the Assign button located at the bottom of the pane.

Note: When assigning licenses to a group, ensure that any service plans with dependencies on other service plans are also assigned. If the dependent service plan is not assigned to the specific group, the assigned license will be disabled.

Assign Admin Roles to Security Groups in Microsoft 365 Admin Center

Navigate to the Teams & groups»Active teams & groups»Security groups in the M365 admin center.
Select the security group to which you want to assign a role.
Under the General tab, locate the Roles category.
Note: This option is available only if the group is enabled for role assignments.
Click Manage roles and select the required roles after opting for Admin center access.
Finally, click the Save Changes button to save your configurations.

How to update Microsoft 365 security groups with dynamic memberships?

Dynamic membership in security groups allows you to automatically manage the membership based on user or device attributes. This is achieved through rules that define the criteria for group membership. For example, you can create a rule to automatically add all users from a specific department or with a certain job title to a security group.

Reasons to Use Microsoft 365 Dynamic Security Groups

Automated Management: Reduce administrative overhead and ensure group memberships are always up-to-date based on predefined criteria.
Consistency and Accuracy: Eliminates human error by consistently applying rules to all users or devices that meet the specified criteria.

Steps to Update Dynamic Group Membership

Sign in to the Microsoft Entra admin center.
Navigate to Identity»Groups»All groups and select Add filter. Set the Group type filter to Security and click Apply to list all the security groups.
Then, select the security group for which you want to change the membership type to dynamic.
Go to the Properties tab and set the Membership type to Dynamic user.
Note: If a group is enabled for assigning Microsoft Entra roles, its membership type cannot be changed to dynamic.
Select the Add dynamic query option and create dynamic rule(s) using the dynamic query builder. To create more than five queries, use the ‘Edit’ option and construct the membership rule queries in the Rule syntax box.
After configuring the rule with the required operators, click Save.
Click Save again on the Properties page to apply the dynamic membership changes.

Once saved, the membership type is immediately updated in the group list. Microsoft first removes all existing members and then adds the group members based on the dynamic rule created.

How to create device groups in Microsoft 365?

Device groups in Microsoft 365 are collections of devices that are grouped together to simplify management tasks, such as applying policies and access controls. These device groups in Intune are essential for admins as they streamline resource management and ensure consistent application of compliance policies across all devices in an organization.

Why Use Security Groups for Device Groups Management?

Only security groups can be used to create device groups in Azure Active Directory. Microsoft recommends using them for device management to fully leverage their potential in security and access control. Here’s why:

Device Membership: Security groups are the only Microsoft 365 group type that allows devices to be members.
Access to Applications and Resources: As security groups control access to applications and resources, adding devices to a security group ensures that only those devices can access specific resources or applications.

In contrast, Microsoft 365 groups (formerly Office 365 groups) are primarily designed for collaboration and do not support device membership. They are better suited for managing access to shared resources like email, calendars, SharePoint document libraries, and more, but not for device management.

Create Device Groups in Microsoft 365

Log in to the New Groups page in the Microsoft Intune admin center.
The group type is set to Security by default, so you can proceed to enter a name and description for the group.
Choose the Membership type as Dynamic device. Then add owners under the Owners section by clicking No owners selected.
Then, add dynamic device members to the group with the Add dynamic query option.
On the Dynamic membership rules page, configure rules using the rule builder or rule syntax text box. Note that the rule builder allows you to create up to five rules only.
Click Create to finalize the device group creation.

By following these steps, you can create device groups in Intune, allowing you to manage and secure your devices efficiently.

How to limit OneDrive access to only specific security groups?

Want to ensure that only the right people in your organization can access OneDrive? Limiting OneDrive access to specific security groups is an excellent way to control who can access the broadly shared OneDrive files. For example, you can prevent guest users from accessing OneDrive content, even if they had access before, ensuring sensitive information stays within the intended audience.

To restrict OneDrive access and sharing, you’ll need one of the following licenses.

Microsoft SharePoint Premium - SharePoint Advanced Management
Office 365 E5/A5
Microsoft 365 E5/A5

Restrict OneDrive Access to a Security Group

Open the Access control page in the SharePoint admin center.
Click on OneDrive access restriction to open the respective flyout pane.
Enable the Restrict OneDrive access only to users in specified security groups checkbox.
In the Add security groups field, search for and select the groups you want to allow access to OneDrive.
Click Save, and then confirm by clicking OK in the confirmation box.

Once you apply this restriction, users outside the specified security groups won’t be able to access their OneDrive or any shared content, even if they’re licensed. The policy takes effect as soon as the users try to access their OneDrive or open a file.

Important Note: Users not in the selected security groups may still see OneDrive files in search results if they have direct permissions. However, they won’t be able to open them without being part of the approved groups. Make sure all required users are included in your security groups before implementing the policy to avoid disrupting workflows.
