Applications that you build on top of APEX are not, by default, magically hacker-proof. Even tight platforms such as APEX have several security concerns. In APEX, these concerns usually center around three main areas: authentication, authorization, and vulnerability exploits.

Authentication refers to the process of checking if the user has rights to access (log in to) the application. This is usually done through a username-password challenge. Authorization is the process of specifying access rights for each user to a particular resource in the application. For instance, an authorization scheme may permit a user to view a report but not to delete it. Finally, security vulnerability exploits—events like SQL injection ...
