This time, the information required for authentication is included and all this information is encrypted in the same way we described earlier. Finally, in step 11, we obtain the response that tells us the request has been successfully executed. As you will notice, this is a more secure authentication method, mainly used if you don't want the overhead of full transport security through TLS/SSL encryption. com/restful-java-web-services-security/source-code/ tree/master/chapter02/digest-authentication Authentication through certificates This is a mechanism in which a trust agreement is established between the server and the client through certificates.

Also, it doesn't have anything to do with the access rights the user has. Security research has specified a list of factors that should be verified in order to achieve positive authentication. This list contains three elements, where it is very common to use two of them, but preferably we should use all of them. These elements are the following: • Knowledge factors: This element implies something the user knows, for example, a password, pass phrase, or personal identification number (PIN). Another example is challenge response, where the user must answer a question, software token, or phone serving as a software token.

In the field Media Type, select application/xml and perform a request with a string that contains the XML with the information, as shown in the following text: ReneEnriquez [ 18 ] Chapter 1 4. When we click on the Play button, we should obtain an answer where it shows the created resource URI (hyperlink "http://localhost:8080/resteasyexamples/services/person/1"), as shown in the following screenshot: 5. If we change the URI from the Resource textbox in SoapUI and use the GET method, it will show us the data we just entered, as shown in the following screenshot: Congratulations!
