Technical guide to support the development of secure restful apis

This study investigates five critical vulnerabilities from the OWASP Top 10 API Security Risks - 2023 (OWASP, 2023) - API2:2023 (Broken Authentication), API4:2023 (Unrestricted Resource Consumption), API5:2023 (Broken Function Level Authorization), API8:2023 (Security Misconfiguration), and API10:2023 (Unsafe Consumption of APIs). The investigative methodology adopted includes an experimental study, utilizing mixed methods (quantitative and qualitative) for data collection and analysis processes. It presents a practical approach to mitigating these issues through the development of a technical guide and an experimental API. The research emphasizes actionable solutions validated through industry feedback and vulnerability testing, providing a valuable resource for secure RESTful API development.
