The configuration set in the web.xml file as indicated by the tag set to CONFIDENTIAL suggests that Oliver, the Server Administrator, is aiming to ensure that all data transmitted between the client and the server is done over an encrypted channel. This is a common security practice to protect sensitive data from being intercepted or tampered with during transmission. Here’s how the setting works:
Enforce HTTPS: The CONFIDENTIAL transport guarantee enforces the use of HTTPS, which encrypts the entire communication channel.
Protect Data: By using HTTPS, not only are the session cookies protected, but all request and response data, including headers and parameters, are encrypted.
Comply with Security Standards: This setting helps in complying with security standards and regulations that mandate encryption of sensitive data in transit.
References: The EC-Council Application Security Engineer (CASE) JAVA documentation and learning resources emphasize the importance of secure data transmission. The use of the CONFIDENTIAL setting in the web.xml file aligns with the best practices for securing web applications deployed on servers like Tomcat12. Additionally, the Java Servlet Specification provides guidelines on how to configure transport guarantees in the deployment descriptor (web.xml) to ensure secure data transmission.
