What is application framework?

A web application framework is software that is designed to support the development of dynamic websites, web application and web services. The framework aims to alleviate the overhead associated with common activities performed in web development. Frameworks are built to support the construction of internet applications based on a single programming language, which augment the capabilities of a specific language, to native-language programmable packages built around a specific user application, such as Content Management systems, some mobile development tools and some portal tools.

How application frameworks become useful for CMS?

In web application frameworks, content management is the way of organizing, categorizing, and structuring the information resources like text, images, documents, audio and video files so that they can be stored, published, and edited with ease and flexibility. A content management system (CMS) is used to collect, manage, and publish content, storing it either as components or whole documents, while maintaining dynamic links between components.

How application framework work for security purpose?

Some web application frameworks come with authentication and authorization frameworks that enable the web server to identify the users of the application, and restrict access to functions based on some defined criteria. Drupal is one example that provides role-based access to pages, and provides a web-based interface for creating users and assigning them roles.
