Definition
A group is a collection of users, computers, or other resources that are managed as a single unit. This allows administrators to assign permissions, policies, and access rights to the entire group at once, rather than individually to each member. Groups simplify administration and enhance security by ensuring consistent application of rules across multiple entities. For instance, a 'Marketing Team' group might be granted access to specific shared drives and applications. This differs from individual user accounts, which manage permissions on a per-user basis. Understanding groups is crucial for domains like identity and access management found in Security+ and CISSP certifications.
