Course Overview

Securing Java Web Services is a lab-intensive, hands-on JEE security training course, essential for experienced enterprise developers who need to produce secure JEE-based web services. In addition to teaching basic programming skills, this course digs deep into sound processes and practices that apply to the entire software development lifecycle.

Designing, implementing, and deploying secure services presents unique challenges.  In addition to dealing with all of the vulnerabilities and attacks associated with web applications, web services must address business-oriented concerns such as authentication, authorization, non-repudiation and others.  The complicating factor is that all measures must be implemented within the constraints of standards and high-level s of inter-operability.

In this course, students thoroughly examine best practices for defensively coding JEE services, including XML processing.  Students will repeatedly attack and then defend various assets associated with fully-functional web services.  This hands-on approach drives home the mechanics of how to secure JEE web services in the most practical of terms.

Security experts agree that the least effective approach to security is "penetrate and patch".  It is far more effective to "bake" security into an application throughout its lifecycle.  After spending significant time trying to defend a poorly designed (from a security perspective) web application, developers are ready to learn how to build secure web applications starting at project inception.  The final portion of this course builds on the previously learned mechanics for building defenses by exploring how design and analysis can be used to build stronger applications from the beginning of the software lifecycle.

PCI Compliant Developer Training

This secure coding training addresses common coding vulnerabilities in software development processes. This training is used by one of the principle participants in the PCI DSS. Having passed multiple PCI audits, this course has been shown to meet the PCI requirements.  The specification of those training requirements are detailed in 6.5.1 through 6.5.10 on pages 55 through 59 of the PCI DSS Requirements 3.0 document dated November, 2013.  This is not "checklist mentality" training as it integrates demonstrations, code flashes, and hands-on labs for vulnerabilities, defenses, and best practices in secure development lifecycle (SDL).

Prerequisites

Familiarity with Java and JEE is required and real world programming experience is highly recommended.  Ideally students should have approximately 6 months to a year of Java and JEE working knowledge.
