How many security groups must be included in an intersection security group?

In Workday, an intersection security group is designed to combine the security permissions of two or more existing security groups. The main purpose of this type of security group is to grant access or permissions that are defined by the intersection of the member groups. Therefore, a minimum of two security groups is required to define the intersections effectively.

Each of these groups contributes a set of permissions that are collectively recognized only when a person is a member of all the groups being intersected. This structure allows for more granular and precise control over data access and security settings, ensuring that only the right individuals have access to sensitive information.

While a security group can be created with the intersection of more than two groups, it is critical to have at least two to fulfill the requirement, making the choice of two the only correct option.
