# API Security Practitioner

> Develop practical API security skills covering OWASP API Top 10, authentication risks, and secure design principles. Learn to defend APIs using mentor-led sessions and practical scenarios focused on testing, hardening, and monitoring.

## Overview

The API Security Practitioner programme is a mentor-led course designed to equip professionals with the skills to identify, assess, and mitigate risks in modern APIs. As APIs become central to digital ecosystems, securing them is critical to protecting sensitive data and ensuring system integrity.

Through practical scenarios, learners will explore the OWASP API Top 10, authentication and authorisation mechanisms such as OAuth and JWT, and common vulnerabilities affecting RESTful and microservices architectures. The course focuses on real-world use cases, enabling participants to understand how attacks occur and how to defend against them responsibly.

Participants will gain hands-on experience with API testing tools, gateway security configurations, and monitoring techniques. By the end of the programme, learners will be able to implement robust API security controls and contribute to secure development and DevSecOps practices.
