How to make Filter applicable only to a Module

I have various modules in my Application such as Authentication , Tickets , Reports ---etc . I want to apply Filters only to the Authentication Module and not to any other Modules . I have written a Authentication filter , My question is that , how can i apply this Authentication Filter applicable only to Authentication Module . 

<filter>
   <filter-name>AuthenFilter</filter-name>
   <filter-class>AuthenFilter</filter-class>
   <init-param>
      <param-name>test-param</param-name>
      <param-value>Initialization Paramter</param-value>
   </init-param>
</filter>


<filter-mapping>
   <filter-name>AuthenFilter</filter-name>
   <url-pattern>/*</url-pattern>
</filter-mapping>

What should be under the url-pattern tag so that its applicable only to the AuthenFilter Module

You should map your filter to particular URI, like this:

<filter-mapping>
   <filter-name>AuthenFilter</filter-name>
   <url-pattern>/modules/login</url-pattern>
</filter-mapping>

or

<filter-mapping>
   <filter-name>AuthenFilter</filter-name>
   <url-pattern>/modules/authentication/*</url-pattern>
</filter-mapping>
