API Security encompasses a set of measures, practices, and techniques aimed at protecting APIs, data, and resources from unauthorized access, data breaches, tampering, misuse, or exploitation by malicious actors, hackers, or attackers. API security controls include authentication (e.g. OAuth, JWT), authorization (e.g. RBAC, ABAC), encryption (e.g. SSL/TLS), input validation, parameterized queries, rate limiting, audit logging, threat modeling, security testing (e.g. penetration testing, fuzzing), and compliance with security standards and best practices (e.g. OWASP API Security Top 10, PCI DSS). API security ensures the confidentiality, integrity, and availability of API services and data assets, safeguarding against common security threats, vulnerabilities, and risks in API ecosystems.
