OWASP API Security Top 10 mitigation strategy using an OIDC/OAuth-compliant server

The OWASP API Security Top 10 is a comprehensive list highlighting the most critical security risks to APIs. In this article, we will take a deep dive into how a robust OIDC/OAuth-compliant server can provide effective strategies to augment solutions to address many of the vulnerabilities listed in the OWASP API Security Top 10. Here’s what to look for in a provider and how to approach with strategic solutions for each vulnerability.

1. Broken Object Level Authorization (BOLA):

Occurs when an API endpoint exposes an object, and the application does not properly enforce access controls, allowing unauthorized users to access or modify that object. For example, An API endpoint allows users to access any account by changing the account ID in the request.

Proposed solution strategy: Secure Resource Access with OAuth Scopes

* Implement OAuth Scopes and Resource-Based Permissions: Utilize OAuth scopes
  and resource-based permissions to restrict user access to authorized
  resources only.

* Fine-Grained OAuth Scope Capabilities: Utilize dynamic or wildcarded scopes,
  such as getAccounts.<account-id>, to define precise authorization requests.

* Employ rich authorization request (RAR) objects, specifying details like
 { "type"…
