Application Security Essentials: Web, API & Mobile Pentesting

In today’s digital landscape, applications span across web, APIs, and mobile platforms — and each introduces its own set of security challenges. This comprehensive course is designed for beginners and aspiring security professionals who want to build a solid foundation in modern application security and penetration testing.

You’ll start with web application security, exploring key concepts, common vulnerabilities like those in the OWASP Top 10, and the dangers of information disclosure. From there, you’ll dive into API security, gaining a deep understanding of API types, architecture, and how to perform effective API pentesting using tools like Postman — all backed by hands-on lab setup guidance.

The final part of the course focuses on mobile application security, covering both Android and iOS platforms. You’ll learn how mobile ecosystems work, understand their architecture, and get introduced to key components, permissions, and tools used in mobile app pentesting. You’ll also learn how to set up real devices or emulators for practical testing.
