Role-Based Access Control (RBAC) in Salesforce Government Cloud manages user permissions and data access. It involves defining roles, profiles, and permission sets. Roles determine access levels and follow a hierarchical structure, with higher roles inheriting permissions from lower ones. Profiles define user capabilities within Salesforce, and permission sets extend these capabilities for specific tasks.
To implement RBAC, create roles based on job functions, configure profiles for necessary access, assign permission sets for extra permissions, and set up a role hierarchy for data visibility. Use sharing rules for specific access needs.
Best practices include granting minimal required permissions (least privilege), regularly reviewing roles and profiles, auditing user activities, and providing training on RBAC. Effective RBAC ensures secure, efficient management of user access and data.
