Course Overview

Exploring 2021 OWASP Top Ten is a seminar style course designed for web developers and technical stakeholders who need to produce secure web applications.  Our web app security expert will share how to integrate security measures into the development process.  You will also explore core concepts and challenges in web application security, showcasing real world examples that illustrate the potential consequences of not following these best practices.

This course will walk you through how to recognize actual and potential software vulnerabilities and implement defenses for those vulnerabilities.  You will explore most common security vulnerabilities faced by web applications today, examining each vulnerability from a coding perspective through a process of describing the threat and attack mechanisms, recognizing associated vulnerabilities, and, finally, designing and implementing effective defenses.

Guided by our application security expert, you will explore how to:

  • Ensure that any hacking and bug hunting is performed in a safe and appropriate manner
  • Identify defect/bug reporting mechanisms within their organizations
  • 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
  • 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

Need different skills or topics?  If your team requires different topics or tools, additional skills or custom approach, this course may be further adjusted to accommodate.  We offer a wide variety of application security, programming and other related topics that may be blended with this course for a track that best suits your needs.  Our team can help design the course or learning path that best meets your needs and skills goals.
