Learning Outcomes - What You Will Learn

Core skills and competencies gained across our Application Security training programmes.

✓ Understand the principles of application security and how to build security into software from the design and development stages

✓ Identify common application vulnerabilities, attack surfaces, security weaknesses, and risks in modern software

✓ Apply OWASP Top 10 principles to identify, exploit, assess, and prevent common web application vulnerabilities

✓ Develop secure web applications using practical secure coding techniques and security controls

✓ Write more secure Python, Java, JavaScript, ASP.NET, and PHP applications

✓ Apply secure coding practices to authentication, input validation, access control, data handling, error handling, and other critical application security areas

✓ Identify and address security risks specific to Python applications used by data analysts, quantitative analysts, and data-focused teams

✓ Understand how insecure code and application vulnerabilities can be exploited and apply practical techniques to reduce attack risk

✓ Use practical security testing and attack simulation techniques to understand how applications may be targeted in real-world scenarios

✓ Build application security into development processes and create software that is more resilient against cyber attacks

Application Security Training for Every Role

Courses matched to your role, technology stack, and application security responsibilities.

🧑‍💻 Software Developers

Learn practical secure coding techniques for web applications and the languages you work with, including Java, JavaScript, Python, ASP.NET, and PHP. Identify common vulnerabilities and build security into applications from the start.

🌐 Web Application Developers

Understand the most common web application security risks and learn how to identify, exploit, and prevent vulnerabilities using practical techniques based on the OWASP Top 10. 

🐍 Python Developers & Data Professionals

Develop secure Python applications and understand security risks relevant to data analysts, quantitative analysts, and other professionals working with Python-based data and analytical environments.

🏗️ Solutions Architects & Technical Leads

Understand application security at the architecture and design level. Identify weaknesses early, establish appropriate security controls, and support development teams in building more resilient applications.

🔒 Security Engineers & Application Security Professionals

Strengthen practical application security capabilities through hands-on secure coding, vulnerability analysis, OWASP techniques, and cyber attack simulation.

🧪 QA, Testing & Security Teams

Learn how vulnerabilities can be identified and exploited, understand application security testing approaches, and work more effectively with development teams to address security weaknesses.

👔 Engineering Managers & Technical Leaders

Develop a practical understanding of application security risks and the techniques development teams can use to reduce vulnerabilities, improve secure coding practices, and build security into the software development lifecycle.

Whether you're a developer securing your own code, a data professional working with Python, a security specialist assessing applications, or a technical leader responsible for software security, this course group provides a practical learning pathway across secure web development, secure coding, Python security, OWASP Top 10, and cyber attack simulation

What Delegates Say - Testimonials

For this section, I would not create new testimonials unless you have verified JBI testimonials specifically for these Application Security courses. It's better for SEO and trust to use genuine feedback from the individual course pages rather than generic invented quotes.

For example, the Java/JavaScript course currently includes delegate feedback describing the course as a useful security refresher with practical resources, and the OWASP course includes feedback about its practical and intermediate-level coverage.

Application Security Training teaches developers, security professionals, architects, testers, and technical teams how to identify, prevent, and manage security vulnerabilities in software and web applications. JBI's Application Security training covers secure development practices, secure coding, OWASP Top 10, Python security, and practical cyber attack simulation.
The courses are suitable for software developers, web developers, application security professionals, cybersecurity specialists, solutions architects, QA and testing professionals, DevOps teams, data analysts, quantitative analysts, and technical leaders responsible for application security.
Depending on the course, delegates can learn how to identify common application vulnerabilities, apply secure coding techniques, protect web applications, address OWASP Top 10 risks, write more secure Python, Java, JavaScript, ASP.NET and PHP code, and understand how applications can be attacked and defended.
Secure Web Application Development focuses on building web applications with security incorporated throughout the development process. Training covers practical approaches to identifying vulnerabilities and implementing appropriate security controls to reduce application security risks.
The OWASP Top 10 is a widely recognised awareness document covering important categories of web application security risks. JBI's OWASP Top 10 Practical Web Application Security course provides practical training in understanding, identifying, exploiting, and mitigating common web application vulnerabilities.
Yes. JBI offers dedicated Python security training covering secure Python development as well as a specialised course for data analysts and quantitative analysts who use Python in their work.
Yes. The Application Security group includes a dedicated Python Security for Data Analysts & Quants course. It focuses on security considerations relevant to professionals using Python for data analysis, quantitative analysis, and related activities.
The Application Security training portfolio includes dedicated secure coding courses covering Java, JavaScript, ASP.NET, PHP, and Python. The exact topics and security techniques vary according to the individual course.
Secure coding is the practice of developing software in a way that reduces security vulnerabilities and protects applications, systems, and data from attack.
