REST APIs provide a high degree of flexibility making it prevalent across the web.</p> <p class="p">Filter criteria contains filter conditions or queries that are used as policy inputs for an authentication policy.</p> <p class="p">You can configure the default Global Blocking Policy or create a custom API access policy according to your security requirements. For example, you can create a custom API access policy that allows only OAuth 2.0 authentication type from a specified range of IP addresses. Authentication requests of other authentication types and access requests from IP addresses other than the specified IP addresses are denied.</p> </div> </body></html></div>
