API security

API security plays an important role in protecting sensitive data by enforcing access controls, authentication, and encryption on the API traffic and ensuring that only authorized entities can access and transmit confidential information securely.

NetScaler allows you to secure the API traffic by validating the incoming API traffic against the imported API specification. An API specification defines the design of an API, including endpoints, methods, parameters, and data formats.

Perform the following configuration to secure the API traffic:

Starting from NetScaler release 13.1 build 53.x, you can protect the authentication and VPN endpoint URLs hosted by NetScaler using a built-in API specification. NetScaler checks the URL traffic to ensure that it is not a potential attack. By default, this feature is disabled. For information on how to enable it, see Authentication methods.

Note:

The Web App firewall protection for authentication and Gateway endpoint is not supported on Linux based CPX and BLX deployments.
