API Security

API Security is the specialized practice within cybersecurity focused on protecting Application Programming Interfaces (APIs), the critical communication pathways that allow different software applications to connect and share data. As APIs expose application logic and sensitive data, they have become a primary attack vector for malicious actors seeking to exploit vulnerabilities such as broken authentication, excessive data exposure, injection flaws, and improper asset management. The discipline involves implementing robust policies, authentication, authorization, and traffic management controls to prevent data breaches, unauthorized access, and denial-of-service attacks, ensuring the integrity and confidentiality of the services foundational to modern web, mobile, and microservices architectures.
