Question:How AngularJS handle the security? 
AnswerAngularJS provide following built-in protection from basic security holes:
1. Prevent HTML injection attacks.
2. Prevent Cross-Site-Scripting (CSS) attacks.

Question:What are Modules in AngularJS? 
AnswerAngularJS modules are containers just like namespace in C#. They divide an angular app into small, reusable and functional components which can be integrated with other angular app. Each module is identified by a unique name and can be dependent on other modules. In AngularJS, every web page (view) can have a single module assigned to it via ng-app directive.

Creating an AngularJS module <script type="text/javascript">
//defining module 
angular.module('myApp', []); 
//OR defining module which has dependency on other modules 
angular.module('myApp', ['dependentModule1', 'dependentModule2']); 
</script>
