What component is used to secure an API in Anypoint Platform?

The correct choice for securing an API in Anypoint Platform is API Manager. API Manager serves as a key component for overseeing and managing APIs within the Anypoint Platform, allowing users to implement various security policies and access controls effectively.

When it comes to securing APIs, API Manager offers capabilities such as applying security policies that define how data is shared and accessed. It enables authentication and authorization mechanisms, ensuring that only authorized users and applications can interact with the API. By using the API Manager, developers can configure security settings like OAuth 2.0, Basic Authentication, API key validation, and IP whitelisting, among others.

In contrast, while the API Gateway does play a role in managing API requests and enforcing some level of security, it primarily focuses on routing and processing API calls rather than being the primary component for defining security settings. The Security Center is intended for monitoring security compliance and threats rather than directly securing APIs. Access Control Lists (ACLs) are used for fine-grained access control but are typically implemented through the API Manager rather than as standalone components for security in Anypoint Platform.
