Training: Instruction to develop new skills.
Hi Hyung Kim,
Thank you for reaching out to Microsoft Q & A forum.
Both security groups and Microsoft 365 groups can be used for this purpose, but the key distinction lies in their primary functions.
Security Groups:
-Primarily used for granting access permissions to resources like files, folders, or shared devices.
-Often employed in on-premises Active Directory environments.
-Can be used to assign permissions within an organization's network.
Microsoft 365 Groups:
-Primarily designed for collaboration in Microsoft 365 (formerly Office 365) services.
-Includes features for sharing files, conversations, and calendars.
-Integrates with services like Exchange, SharePoint, and Teams.
While both types of groups allow you to manage permissions, the context of the question might be emphasizing a scenario where the primary purpose is to manage permissions, and in that context, a "security group" the more direct answer.
Whether you need security groups or Microsoft 365 groups depends on the type of access you are trying to set up for your users, and whether any of the limitations mentioned above apply to your scenario.
