What is one method to secure a Liferay application?

Implementing role-based access controls is a foundational security measure for Liferay applications. This method allows you to define and manage permissions based on user roles, ensuring that only authorized users have access to certain functionalities and content within the application. By assigning specific roles, such as administrator, editor, or viewer, you can tailor access rights to meet business requirements and protect sensitive information.

This approach is crucial in a collaborative environment like Liferay, where multiple users might need varying levels of access to perform their tasks effectively. It minimizes the risk of unauthorized access and potential data breaches by allowing precise control over who can view, edit, or manage specific resources.

While other choices such as application-level encryption and restricting IP addresses can enhance security in particular contexts, role-based access controls provide a comprehensive framework for managing user permissions and protecting the overall integrity of the application. Maximizing server performance, while important for ensuring that the application runs smoothly, does not directly address security concerns.
