How to define security requirements for your OSS project

This installment of GitHub Security Lab's series on the OWASP Top 10 Proactive Controls emphasizes the importance of establishing security requirements for open-source software (OSS) projects to enhance security posture. It highlights that defining security needs is crucial even before coding begins, as it sets a baseline for compliance and fosters a security-focused mindset. The OWASP Application Security Verification Standard (ASVS) is presented as a valuable resource, offering a catalog of security requirements and verification criteria categorized into 14 domains, which can be tailored to specific project needs based on relevance and risk level. The article provides an example of filtering these requirements for a node library to perform URL parsing, demonstrating how domains like threat modeling and validation can be selectively applied. It also outlines the three risk levels, from basic to high assurance, to help developers incrementally build security measures. The piece concludes by assuring that using ASVS simplifies the process of identifying security needs, with future posts set to explore verification methods through static and dynamic analysis.
