Course Overview
TopAttacking and Securing .Net Web Applications is a lab-intensive, hands-on .Net security training course that provides unique coverage of .Net application security. In this course, students begin with penetration testing, hunting for bugs in .Net web applications. They then thoroughly examine best practices for defensively coding web applications, covering all the OWASP Top Ten as well as several additional prominent vulnerabilities (such as file uploads, CSRF and direct object references). Students will repeatedly attack and then defend various assets associated with fully functional web applications and services. This hands-on approach drives home the mechanics of how to secure .Net web applications in the most practical of terms. The course ends with an extensive discussion of what a mature application security presence would provide to the developers within an organization.
A key component to our Best Defense IT Security Training Series, this workshop is a companion course with several developer-oriented courses and seminars. Our bug hunting class introduces penetration testing , illustrating how hackers probe and exploit our applications. Our developing secure software class introduces various security measures that can be applied through the software lifecycle. The combination of ethical hacking, secure coding, and secure lifecycle training provides student with the complete experience in application security. This course merges these classes with a specific .Net orientation. Although this edition of the course is Java specific, it may also be presented using Java, NodeJS or other programming languages.
Course Schedule
TopTarget Audience
TopThis is an intermediate-level programming course, designed for experienced .Net developers who wish to get up and running on developing well defended software applications. Real world programming experience with .Net is required.
Course Objectives
TopStudents who attend Attacking and Securing .Net Web Applications will leave the course armed with the skills required to recognize actual and potential software vulnerabilities and implement defenses for those vulnerabilities. This course begins by developing the skills required to fingerprint a web application and then scan it for vulnerabilities and bugs. Practical labs using current tools and techniques provide students with the experience needed to begin testing their own applications. Students also gain a deeper understanding of how attackers probe applications to understand the runtime environment as well as find potential weaknesses. This course the introduces developers to the most common security vulnerabilities faced by web applications today. Each vulnerability is examined from a .Net perspective through a process of describing the threat and attack mechanisms, recognizing associated vulnerabilities, and, finally, designing, implementing effective defenses.
Practical labs reinforce these concepts with real vulnerabilities and attacks. Students are then challenged to design and implement the layered defenses they will need in defending their own applications. There is an emphasis on the underlying vulnerability patterns since the technologies, use cases, and methods of attack as constantly changing. The patterns remain the same through all the change and flux.
This “skills-centric” course is about 50% hands-on lab and 50% lecture, designed to train attendees in secure web application development, coding and design, coupling the most current, effective techniques with the soundest industry practices. Our instructors and mentors are highly experienced practitioners who bring years of current "on-the-job" experience into every classroom.

Course Content
TopPlease note that this list of topics is based on our standard course offering, evolved from typical industry uses and trends. We’ll work with you to tune this course and level of coverage to target the skills you need most. Topics, agenda and labs are subject to change, and may adjust during live delivery based on audience interests and skill-level.
