What is JAAS

JAAS (Java Authentication and Authorization Service) is a standard Java library that allows users to authenticate and authorize access to protected resources in Java applications. It provides a framework for developers to implement different security mechanisms, making it easier to manage user identities and permissions in their applications.

// Example of JAAS Configuration LoginContext loginContext = new LoginContext("MyLoginModule", new CallbackHandler() { public void handle(Callback[] callbacks) throws IOException, UnsupportedCallbackException { // Handle user input for authentication } }); loginContext.login(); // Authenticates the user // Check user roles and permissions after authentication
