Java Training Overview

This course shows Java web developers how to secure their applications and to apply best practices with regard to secure enterprise coding. Authentication, authorization, and input validation are major themes, and students get good exposure to basic Java cryptography for specific development scenarios, as well as thorough discussions of HTTPS configuration and certificate management, error handling, logging, and auditing.

Perhaps the most eye-opening parts of the course concern common web "hacks," or attack vectors. Students see how easy it is to leave an application unguarded against cross-site scripting (XSS), cross-site request forgery (CSRF), SQL injection, and other attack types -- and learn that it's also easy to fix such vulnerabilities and the importance of a secure development process.

Java Training Prerequisites
  • Java programming experience is essential -- Course "Java Programming" is excellent preparation.
  • Servlets programming experience is required -- Course "Java Servlets"
  • JSP page-authoring experience is recommended but not required
Java Training Learning Objectives

After completing this course, the student should be able to:

  • Generally, be prepared to develop secure Java web applications, or to secure existing applications by refactoring as necessary.
  • Define security constraints and login configurations that instruct the web container to enforce authentication and authorization policies.
  • Guard against common web attacks including XSS, CSRF, and SQL injection.
  • Validate user input aggressively, for general application health and specifically to foil injection and XSS attacks.
  • Configure a server and/or application to use one-way or two-way HTTPS.
  • Apply application-level cryptography where necessary.
  • Store sensitive information securely, hash user passwords, and understand the importance of salting and of using slow hashing algorithms and processes, to maximize the safety of stored credentials.
  • Secure log files and establish audit trails for especially sensitive information or actions.
Server Support: Tomcat

This version of the course works with the Tomcat server. Our Java EE courses are available in variants that support various server products, including Tomcat, GlassFish, JBoss, and WebLogic.

Appendix A. Learning Resources

System Requirements

Hardware Requirements (Minimum) Core i5, 1.8 GHz, 4 gig RAM, 1 gig disk space.
Hardware Requirements (Recommended) Core i5, 2.5 GHz GHz, 8 gig RAM, 1 gig disk space.
Operating System Tested on Windows 7 and 8, Mac OS 10.8. Most exercises are fully portable over operating systems, web servers, and major web browsers. The demonstration of HTTPS-configuration in Chapter 5 focuses on Internet Explorer 10 and Tomcat 8, with brief notes on configuration for other browsers. Browsers continue to evolve rapidly -- especially where security is concerned -- and other configurations desired in the classroom should be tested by the instructor prior to class time.
Network and Security Limited privileges required
Software Requirements All free downloadable tools.
