Introduction to Data Integrity and Confidentiality in Java EE web applications

Data integrity is the process of verifying if data is transmitted without corruption or modification, thus making sure that the data received at the receiver end is in fact the same message sent by the sender.  Confidentiality is the process of maintaining data privacy wherein we secure the communications channel, to make sure the data is not accessed in its original form by a third party by eavesdropping.

Confidentiality and data integrity are related to securing the communications channel.

What will happen if you specify transport guarantee as INTEGRAL or CONFIDENTIAL without configuring certificates?

In the response for first request to a non secure url, you will get a redirect url to a new https url, as you can see from tcpmon capture:

What will happen if you use FORM authentication without configuring a login page?

You will get an error: HTTP Status 500 - No login page was defined for FORM authentication in context.

What will happen if you use CLIENT-CERT authentication without configuring certificates?

You will get an error: HTTP Status 401 - No client certificate chain in this request.

[Demo] Basic and Digest Authentication using Apache Tomcat server Part 2 - Looking into the transmitted password data from client to server

This is the second part of the demo on Basic and Digest Authentication using Apache Tomcat server. We have already created the setup, did necessary configurations within web.xml and tomcat’s tomcat-users.xml, and finally exported it as a war, deployed it into tomcat and tested the basic and digest authentication.
