API Security
- API security is critical because APIs (Application Programming Interfaces) are the backbone of many modern applications and allow for communication between different software components.
- Hackers can target vulnerabilities in APIs to gain access to sensitive data, execute malicious code, or even take over entire systems.
- API security breaches can have severe consequences, including financial losses, damage to reputation, and legal liabilities. Ensuring the security of APIs is crucial for protecting organizations and their customers from cyber threats.
OWASP API Security Project
- The OWASP (Open Web Application Security Project) API Security Top 10 list provides a framework for identifying and addressing common API security risks.
- Recently, OWASP announced the first release candidate for the API Security Top 10 - 2023
