The Open Worldwide Application Security Project (OWASP) is a nonprofit organization dedicated to improving software security. Through resources, tools, and guidance, OWASP supports developers, application architects, and security professionals in building secure applications. One of OWASP's most well-known contributions is its Top 10 list of the most critical web application security risks. This list helps organizations focus their security efforts on the latest threats and vulnerabilities.

However, as software ecosystems increasingly rely on APIs (Application Programming Interfaces), OWASP has expanded its focus. APIs, which enable communication and data exchange between different software systems, are the backbone of modern enterprises. With API-driven implementations exploding across cloud, on-premise, and edge environments, securing APIs has become more crucial than ever. To address this, OWASP introduced the API Security Top 10—a comprehensive guide detailing the most critical security risks facing APIs.

OWASP API Top 10 (2023 )

The OWASP API Security Top 10 highlights the most significant risks to APIs in 2023:

  1. Broken Object Level Authorization (BOLA)

  2. Broken Authentication

  3. Broken Object Property Level Authorization

  4. Unrestricted Resource Consumption

  5. Broken Function Level Authorization

  6. Unrestricted Access to Sensitive Business Flows

  7. Server Side Request Forgery (SSRF)

  8. Security Misconfiguration

  9. Improper Inventory Management

  10. Unsafe Consumption of APIs

With the rise of API-related attacks, these vulnerabilities present significant risks. According to a recent report ¹, 61% of attacks in the past year were authentication-based, highlighting the importance of robust API security practices.

Addressing API Security with Corsha

Corsha takes an identity-first approach to API security. By dynamically tracking machine identities and enforcing multi-factor authentication (MFA) for every API request, Corsha helps mitigate risks outlined in the OWASP API Top 10. Below is a breakdown of how Corsha helps organizations defend against specific vulnerabilities.

Why OWASP API Security Matters

As APIs become more prevalent, they introduce unique vulnerabilities that must be prioritized by organizations. The OWASP API Top 10 serves as an important guide for understanding and mitigating API security risks. By addressing the security concerns identified in the Top 10, organizations can prevent data breaches, service disruptions, and other damaging attacks.

OWASP has announced plans to release the OWASP Top 10: 2025 in the first half of next year, further updating its guidance on the most critical web application security risks. To learn more about the OWASP API Top 10 and the OWASP API Security Project, visit OWASP API Security.
