About this course

About this course

Course Overview

Modern organisations rely heavily on web applications, and attackers exploit their weaknesses daily.

As AI tools accelerate software development, code is being generated faster than ever before. Yet every line, human-written or AI-generated, still carries risk. This instructor-led course gives participants the knowledge and practical experience to recognise vulnerabilities, understand how exploitation works, and assess potential impact.

Aligned with the latest OWASP Top 10 2025, the course provides an in-depth exploration of each key risk, illustrated through demonstrations and guided labs.

Participants will learn how attackers think, how vulnerabilities are introduced, and how to recognise and validate them — preparing teams to collaborate effectively with developers and security engineers in future remediation work.

AI may change how we build applications, but not the need to understand how they break.

Why Take this Course?

  • Reduce risk by building security into every stage of your software lifecycle.

  • Identify vulnerabilities and misconfigurations before they reach production.

  • Improve compliance with frameworks like ISO 27001, PCI DSS, and NIST SSDF.

  • Gain hands-on experience in exploiting and remediating real-world vulnerabilities.

  • Learn directly from an internationally recognised instructor with deep industry experience.

Learning Objectives

After completing this course, participants will be able to:

  • Use the OWASP Top 10 as a reference for identifying, testing, and remediating web security issues.
  • Identify each category of the OWASP Top 10 2025, describe how vulnerabilities are exploited and the impact of exploitation.
  • Assess and prioritise risks introduced by both human-written and AI-generated code.
  • Demonstrate how exploitation occurs through hands-on labs.
  • Analyse each stage of the Secure Development Lifecycle (SDL) and its role in preventing vulnerabilities.
  • Collaborate effectively with development and security teams to ensure vulnerabilities are remediated before production.
  • Apply learned knowledge to validate code for security soundness.

Who Should Attend this Course?

  • Web developers and DevSecOps engineers.
  • Testers and QA professionals validating AI-assisted or human code.
  • Security analysts, auditors, and penetration testers.
  • IT managers and product owners accountable for application assurance.

Pre-requisites: Basic understanding of web technologies (HTTP, HTML, Javascript). Basic coding experience required.

Format

Our Web Application Security Essentials course offers a dynamic, hands-on learning experience led by internationally recognised instructors. Combining real-world examples with interactive sessions, it balances theory and practice to help participants understand how web vulnerabilities arise and are exploited.

You will begin by exploring common web application vulnerabilities before gaining access to a purpose-built lab environment containing the bugs and coding errors discussed in class. This provides an ideal, safe setting to observe and exploit these vulnerabilities using open-source tools and techniques, bridging the gap between theory and real-world practice.

This practical approach builds the confidence and analytical skills needed to identify and assess security risks effectively. Sessions encourage active participation, group discussions, and collaboration, allowing you to share insights and learn from peers across disciplines.
