Harness's Security Testing Orchestration (STO) module automates API security testing within the DevOps pipeline to address vulnerabilities, including those outlined in the OWASP Top 10, thereby integrating security into the development lifecycle and enhancing DevSecOps maturity. As APIs become increasingly central to modern software development, the importance of a robust API security testing strategy has grown, especially given the rise in API-related cyberattacks. API security testing involves identifying vulnerabilities to prevent attacks and ensure APIs meet their defined specifications, focusing on potential issues like authorization bypasses and data exposure. Harness's methodology emphasizes continuous testing as part of the development cycle, combining automated tools with manual testing to address both common and business-specific vulnerabilities, and involves steps such as scoping, mapping attacks, and automating testing processes to keep pace with software delivery. The strategy highlights the necessity of ongoing testing and adaptation to maintain API security, supporting the organization's broader security posture as APIs play a crucial role in applications and digital transformations.
