In Active Directory Users and Computers "Security Enabled" groups are simply referred to as Security groups. AD has 2 types of groups: Security and Distribution. Distribution (security disabled) groups are for distribution lists in Exchange and cannot be assigned permissions or rights. Security (security enabled) groups can be used for permissions, rights and as distribution lists.

Universal means the group can be granted access in any trusting domain and may have members from any trusted domain.

This event is only logged on domain controllers.
