Securing Web Applications | Latest OWASP Top Ten and Beyond (TT8120)

Learning Objectives

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.

This course combines engaging instructor-led presentations and useful demonstrations with valuable hands-on labs and engaging group activities. Throughout the course you’ll:

• Grasp defensive, secure coding concepts and terminology, including the understanding of exploit phases and goals.
• Explore the 2021 OWASP Top Ten (latest edition) as well as several additional prominent vulnerabilities.
• Master the first axioms in security analysis and addressing security concerns across all web applications.
• Learn how to perform ethical hacking and bug hunting in a safe and appropriate manner.
• Identify and utilize effective defect/bug reporting mechanisms within your organization.
• Learn how to avoid common pitfalls in bug hunting and vulnerability testing.
• Develop an appreciation for the value of a multilayered defense strategy.
• Understand potential sources of untrusted data and the consequences of improper handling.
• Comprehend the vulnerabilities associated with authentication and authorization mechanisms.
• Learn how to detect and mitigate threats to authentication and authorization functionalities.
• Understand the mechanics and threats of Cross-Site Scripting (XSS) and Injection attacks, and how to defend against them.
• Comprehend the risks associated with XML processing, software uploads, and deserialization, and learn mitigation strategies.
• Familiarize yourself with security tools, hardening techniques, ongoing threat intelligence resources
• Optional / Bonus: Exploring AI in Web Application Security

Audience

This is an overview-level course ideally suited for web developers, software engineers, system administrators, and other technical stakeholders who are involved in the design, development, or maintenance of web applications. Security professionals looking to deepen their understanding of web application vulnerabilities and defense mechanisms would also greatly benefit. Moreover, project managers and leaders who wish to ensure their teams are following best practices for secure application development will find this course valuable in shaping their strategic direction.

Pre-Requisites
