There are several steps involved in defining a role-based access control (RBAC) model:
- Identify the roles that exist in your organization: Start by identifying all the roles that exist within your organization, including employees, contractors, and external partners. Consider the responsibilities and tasks associated with each role and how they fit into the overall organizational structure.
- Define the permissions and privileges associated with each role: Next, determine the permissions and privileges that are necessary for each role to perform their duties effectively. This may include access to certain systems, data, or resources.
- Create a hierarchy of roles: Depending on the size and complexity of your organization, you may want to create a hierarchy of roles to reflect the relationships between different roles and their relative levels of authority.
- Establish a process for granting and revoking access: Decide on a process for granting and revoking access to resources and systems based on role. This may involve creating request forms and establishing an approval process.
- Document the RBAC model: Document the RBAC model in a clear and concise manner, including details on the roles, permissions, and privileges associated with each role, as well as the process for granting and revoking access. This documentation should be made available to all relevant parties.
- Review and update the RBAC model regularly: It is important to review and update the RBAC model regularly to ensure that it continues to reflect the needs of the organization and the roles within it. This may involve adding new roles, revising existing roles, or changing the permissions and privileges associated with a role.
