How can you manage user permissions for portlets in Liferay?

In Liferay, user permissions for portlets can be efficiently managed through the Control Panel by navigating to the "Roles" and "Permissions" sections. This method allows administrators to define and assign specific roles to users, which in turn dictate what actions those users can perform within the portal, including accessing and interacting with various portlets.

Using the Control Panel provides a user-friendly interface where permissions can be configured without the need for coding or direct database manipulation. This approach is scalable and maintains the integrity of the permissions system, as it leverages Liferay’s built-in mechanisms for user role management. By utilizing roles, administrators can easily assign permissions in bulk, making it practical when managing large user bases or multiple portlets.

The other approaches, such as modifying the database directly, using an external user management system, or coding permissions into each portlet, pose significant challenges. Direct database modifications are risky and can lead to system instability or data corruption. An external user management system may require additional integration work and could complicate the permission management process. Furthermore, coding permissions into each portlet is inefficient and does not take advantage of Liferay's robust permission management features, making it harder to maintain and update permissions across different portlets.

Thus, the most effective
