Access group

An access group is a cybersecurity and Identity & Access Management (IAM) mechanism that logically bundles users, applications, or devices requiring the same set of permissions to specific digital resources within an organization. Instead of assigning permissions individually to each user or entity, administrators grant them collectively to the group, which automatically applies those rights to all its members. This approach dramatically improves administrative efficiency, reduces configuration errors, and strengthens security by enabling consistent enforcement of the principle of least privilege.

Access groups serve as a critical control for managing who can perform what actions on which assets—from network shares and databases to cloud services and critical infrastructure. Their effective implementation simplifies audit processes, supports regulatory compliance, and helps prevent unauthorized access, privilege escalation, and data breaches across complex IT environments. By centralizing authorization management, access groups enable organizations to scale their security policies systematically as their user base and technological landscape grow.
