SECURING .NET WEB APPLICATIONS (TT8320-N)

In this course, you will thoroughly examine best practices for defensively coding .NET web applications, including XML processing and web services. You will repeatedly attack and then defend various assets associated with a fully-functional web application. This hands-on approach drives home the mechanics of how to secure .NET web applications in the most practical of terms. This workshop is a companion course with several developer-oriented courses and seminars. Although this edition of the course is .NET-specific, it may also be presented using JEE or other programming languages.

PCI Compliant Developer Training: Version 3.0 of the Payment Card Information Data Security Standard (PCI-DSS) and the Payment Application Data Security Standard (PA-DSS) have placed an increased emphasis on information security training and awareness. This class can help meet the annual training requirements for your developers and vendors. 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.
