What You'll Learn
Advanced Web App Architecture & Threat Modeling
Analyse complex web application components and identify attack vectors through systematic threat modelling.
Secure Input Validation & Output Encoding
Implement robust secure coding practices to prevent common and advanced injection flaws, including XSS, SQLi, and command injection vulnerabilities.
Resilient Authentication & Session Management
Design, implement, and rigorously test resilient authentication mechanisms and secure session handling protocols to prevent unauthorized access.
Comprehensive API Security Testing
Test RESTful and GraphQL APIs for security vulnerabilities, misconfigurations, and business-logic flaws.
OWASP Top 10 In-Depth Exploitation & Mitigation
Study the OWASP Top 10 through controlled exploitation labs and remediation planning.
Professional Security Code Review Techniques
Learn to perform comprehensive security code reviews using a combination of manual analysis, automated SAST tools, and industry best practices.
DevSecOps: CI/CD Security Integration
Understand and implement strategies for integrating automated security testing (SAST, DAST, IAST) into modern DevOps pipelines and CI/CD workflows.
Effective Vulnerability Assessment & Reporting
Conduct vulnerability assessments and write actionable security reports for technical and executive audiences.

- 7
Week 7: Automating AppSec: DevSecOps & CI/CD Pipelines
Integrate dynamic security testing (DAST) and other security checks into CI/CD pipelines using GitHub Actions and other DevSecOps automation tools.
- 8
Week 8: Capstone: Full-Scope Web App Pentest & Portfolio
Conduct a scoped penetration test of a complex web application, document the findings, and prepare a sanitised portfolio extract.
Capstone project
Assess an intentionally vulnerable web application under a written scope and fictional business context
- Combine manual testing, automated scanning, and targeted source review to validate exploitable weaknesses
- Trace each confirmed issue to affected code or configuration and propose a practical secure-coding fix
- Add a lightweight SAST or DAST quality gate and document false positives separately from validated findings
- Deliver a technical assessment, developer remediation matrix, retest notes, and a concise risk briefing
- Show only sanitised code snippets and lab screenshots; do not publish exploit chains, secrets, or deployable vulnerable code
Eligibility & Prerequisites
Eligibility
- Enrolled in or recent graduate of a Cybersecurity, Computer Science, or Software Engineering degree.
- Proficiency in at least one programming language (e.g., Python, Java, JavaScript, C#).
- Strong understanding of web technologies (HTML, CSS, JavaScript, HTTP/S protocols, REST APIs).
- Demonstrable passion for ethical hacking, vulnerability research, and secure software development.
- Excellent analytical, problem-solving, and critical thinking capabilities.
- Commitment to an intensive 8-week program focused on practical, hands-on learning.
Prerequisites
- Completion of intermediate-level courses in web development or software engineering.
- Solid understanding of common web application vulnerabilities (e.g., OWASP Top 10 basics).
- Experience with command-line interfaces and basic scripting.
- Familiarity with web browser developer tools for inspection and debugging.
- Working knowledge of version control systems, particularly Git and GitHub.
- Fundamental understanding of databases (SQL/NoSQL) and network protocols.
Why choose this internship?
Connects web testing with code review and secure delivery rather than treating vulnerabilities as scanner output
Broader than API Security because it covers browser behaviour, server logic, source code, and pipeline controls
Matches junior AppSec support tasks: triage, reproduction, developer guidance, and remediation verification
Creates portfolio-safe evidence through redacted findings, secure-code examples, and CI security checks
Use only designated applications; related progression includes API Security or DevSecOps
