As applications transition to microservices and API-first architectures, the attack surface shifts significantly. API security testing requires evaluating logical flaws and authorization bypasses that automated scanners often miss.
Modern web applications rely heavily on APIs. However, API security testing requires a fundamentally different approach than traditional web application scanning.
Broken Object Level Authorization (BOLA)
BOLA occurs when an application does not properly validate that the user requesting an object has the permissions to access it. Attackers can manipulate object IDs in API requests to access sensitive data.
WARNING
Automated scanners frequently miss BOLA vulnerabilities because they require an understanding of business logic and multi-user context.
