This 2025-focused whitepaper revisits the OWASP API Security Top 10 (2023) and explains why common controls like WAFs and API gateways often miss API-specific abuse because they lack business context and behavior baselines. It walks through risks such as broken object and function authorization, broken authentication, property-level authorization gaps, resource exhaustion, sensitive business-flow abuse, SSRF, security misconfiguration, weak API inventory management, and unsafe consumption of third-party APIs, pairing each with typical impacts and examples. It positions Salt Security’s approach as continuous traffic analysis that learns normal API behavior, detects anomalies, and helps block and remediate attacks with real-time context and insights.
