+    	<question>Will Spring Security take care of all my application security requirements?</question>
+    	<answer>
+    		<p>Spring Security provides you with a very flexible framework for
+    			your authentication and authorization requirements, but there are many other considerations
+    			for building a secure application that are outside its scope. Web applications are
+    			vulnerable to all kinds of attacks which you should be familiar with, preferably before you 
+    			start development so you can design and code with them in mind from the beginning. 
+    			Check out the <a href="http://www.owasp.org/">OWASP web site</a>
+    			for information on the major issues facing web application developers and the countermeasures
+    			you can use against them.
