6.6 Configure Role-Based Access Control (RBAC)
Role Based Access Control (Role Based Access Control, RBAC) is a feature within PCCU32 that allows
an administrator to designate roles and control access levels to various applications and processes in
the flow computer. The G5 and newer flow computers and NGC devices support RBAC security files.
Each security file is configurable for the specific device type.
When designing an RBAC security system, consider all required user-access to the system. Create the
users and an administrator and assign a default role to each.
RBAC security configuration restricts or disables any unapproved applications and functions for the
current user. Restricted applications and restricted functions are not visible on the PCCU32 navigation
tree. The Send button is also grayed out on applications with read-only functionality.
