Want to learn how cybersecurity professionals discover vulnerabilities in APIs and backend services? This practical course is designed to help you understand API security testing from the fundamentals to real-world assessment techniques.

I am a cybersecurity professional with 4+ years of hands-on experience in offensive security, penetration testing, and vulnerability research, with exposure to 50+ security projects across multiple industries. As a Security Analyst in a cybersecurity organization, I bring practical industry knowledge and testing methodologies to help students understand how professional API security assessments are conducted.

What you will learn:

API Fundamentals: HTTP methods, status codes, headers, JSON, REST architecture, and web service communication.
API Reconnaissance: Endpoint discovery, API documentation analysis, and attack-surface mapping.
Authentication Testing: Login mechanisms, session handling, token validation, and JWT security.
Authorization Testing: IDOR, Broken Object Level Authorization (BOLA), privilege escalation, and Broken Function Level Authorization (BFLA).
Input Validation: SQL injection, command injection, XSS-related API issues, and other injection vulnerabilities.
Business Logic Testing: Workflow manipulation, parameter tampering, and unauthorized actions.
Access Control Testing: HTTP method restrictions, role-based permissions, and server-side validation.
Rate Limiting and Abuse: Testing throttling controls and protection against excessive requests.
Sensitive Data Exposure: Identifying excessive data disclosure, information leakage, and insecure error handling.
Security Tools: Practical use of Burp Suite, Postman, curl, and other relevant testing utilities.
Professional Reporting: Writing vulnerability reports with proof of concepts, risk ratings, and remediation guidance.

This class is suitable for college students, beginners, web application penetration testers, developers, and aspiring bug bounty hunters. Basic knowledge of HTTP and web applications is helpful but not mandatory.

Requirements: Bring a laptop, a stable internet connection, and a willingness to practice. Testing will be performed using authorized labs and environments where permission has been granted.

The goal is to help you build practical API security skills, understand industry assessment workflows, and work toward cybersecurity internships and entry-level penetration-testing opportunities.

4 Years of Experience

Cybersecurity professional with 4+ years of hands-on experience in offensive security, penetration testing, vulnerability assessment, and application security. Experienced in assessing and securing web applications, APIs, Android applications, network infrastructure, Linux environments, and Windows/thick client applications. I have worked across 50+ cybersecurity projects for clients from diverse industries, including FinTech, healthcare, medical, sales, enterprise, and other business-critical environments. My experience includes conducting end-to-end security assessments, identifying vulnerabilities, developing proof-of-concepts, validating security impact, and preparing professional technical reports with remediation recommendations. In addition to professional penetration testing, I have approximately 1 year of bug bounty experience, during which I independently discovered and responsibly reported security vulnerabilities affecting various organizations. My bug bounty contributions have resulted in cash rewards, swag, and Hall of Fame recognition from organizations including NASA, Apple, Syncfusion, and several other companies. Core experience includes web application penetration testing (authentication, authorization, access control, injection, XSS, SSRF, file upload, business logic, API security, client-side vulnerabilities, and other OWASP-aligned vulnerabilities), API security testing (REST/JSON APIs, authentication mechanisms, authorization and IDOR testing, token validation, business logic, rate limiting, API abuse cases, and endpoint security), Android security testing (APK analysis, static and dynamic analysis, Android application security, API interception, authentication/authorization testing, secure storage, deep links, SSL/TLS validation, and runtime analysis), network penetration testing (network enumeration, service assessment, vulnerability identification, exploitation validation, and security hardening recommendations), Linux security (Linux privilege escalation, service enumeration, misconfiguration analysis, permissions, exposed services, and post-exploitation security assessment), Windows and thick client security (Windows application and thick-client assessments, authentication/authorization testing, insecure configurations, local security controls, sensitive data exposure, and application-level vulnerabilities), social engineering and phishing assessments (experience with authorized phishing simulations and security-awareness assessments to evaluate organizational resilience against social-engineering threats), and bug bounty hunting (independent vulnerability research, reconnaissance, vulnerability discovery, exploitation validation, responsible disclosure, and communication with security teams). My professional experience combines technical penetration-testing skills with practical understanding of cybersecurity operations and business requirements, allowing me to translate technical vulnerabilities into meaningful business risks and actionable remediation recommendations. This experience has strengthened my ability to think beyond standard security checklists, identify unconventional attack paths, understand application logic, and validate vulnerabilities from an attacker's perspective.
