True or False: If a user belongs to multiple security groups, they'll receive the highest permissions from the combination of groups.

The statement is true because in many systems, including those that use role-based access control, a user's permissions are calculated based on the cumulative permissions granted by all of the security groups they belong to. This means that if a user is part of multiple security groups, the highest level of permissions granted to them from any of those groups will be the effective permissions they receive.

This model allows for greater flexibility, as it enables users to have varied permissions based on their role in different areas of the organization. For example, if a user belongs to one group that allows them read access to certain files and another group that grants write access to the same files, the user would effectively have write access because it is the higher permission granted by the combination of groups.

While it is important for users to have the necessary permissions to perform their job functions, it is also critical for organizations to manage and audit these permissions to avoid potential conflicts or security risks arising from overlapping privileges. In this context, factors such as the primary group or the presence of conflicting permissions can complicate the management of permissions, but they do not negate the overall principle that a user will receive the highest permissions from their combined group memberships.
