Group-based access control allows access to system resources based on predefined groups, rather than individual users. The concept groups different users or attributes such as roles, departments or levels of authority into one group, so it is easier to manage and control access to resources based on a particular set of users.
Users are assigned to a specific group based on their attributes, roles or responsibilities. Access control lists (ACLs) are created based on these groups, specifying access permissions to various resources like applications, files or databases. When a user is added to a particular group, they automatically receive the access rights and permissions associated with that group.
With group-based access control, administrators can easily manage permissions for large numbers of users by grouping them based on their access requirements. Access can also be easily revoked or modified by removing users from a group or changing the group’s permissions. This approach reduces the complexity of managing individual user permissions and ensures that users only have access to the resources they need to complete their work.
