.Net Secure Coding Camp | Attacking and Securing .Net Web Apps (for .Net Core 6)|System Source

Attacking 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.

Please note this class uses the latest version of .Net Core / Version 6.

Working in a dynamic, lab-intensive hands-on coding environment students will learn to:

Ensure that any hacking and bug hunting is performed in a safe and appropriate manner
Identify defect/bug reporting mechanisms within their organizations
Work with specific tools for targeted vulnerabilities
Avoid common mistakes that are made in bug hunting and vulnerability testing
Understand the concepts and terminology behind defensive, secure coding including the phases and goals of a typical exploit
Develop an appreciation for the need and value of a multilayered defense in depth
Understand potential sources for untrusted data
Understand the consequences for not properly handling untrusted data such as denial of service, cross-site scripting, and injections
To test web applications with various attack techniques to determine the existence of and effectiveness of layered defenses
Prevent and defend the many potential vulnerabilities associated with untrusted data
Understand the vulnerabilities of associated with authentication and authorization
Detect, attack, and implement defenses for authentication and authorization functionality and services
Understand the dangers and mechanisms behind Cross-Site Scripting (XSS) and Injection attacks
Detect, attack, and implement defenses against XSS and Injection attacks
Understand the risks associated with XML processing, file uploads, and server-side interpreters and how to best eliminate or mitigate those risks
Understand techniques and measures that can used to harden web and application servers as well as other components in your infrastructure
