OAuth was created to be a standardization of several internet protocols, including Secure Socket Layer (SSL), Transport Layer Security (TLS), Hypertext Transfer Protocol (HTTPS) and Access-Control Lists (ACL). An application programmer can implement OAuth through a browser. The browser must include the OAuth plugin or else the application will not work. OAuth is often integrated into HTML pages to provide security.
OAuth allows web browsers to be more secure and offer better security by allowing an application to provide sensitive information to a server where it can then be stored and accessed only with authorization from the user’s browser. OAuth also provides an easy, flexible and convenient authentication process.
OAuth works well for web applications because it allows the application to store information in the server itself. The server does not need to store all the information as it only needs to hold authorization codes that the client has provided. These authorization codes can then be used by the browser to verify the user’s identity before granting them access to the server’s resources. OAuth allows web applications to provide security for sensitive data while maintaining simplicity and security.
OAuth offers security to web servers and enables application developers to securely communicate with the server. Web applications can also be protected using OAuth by limiting unauthorized access by allowing only authorized users to have access to the server.
Application developers can create OAuth compatible libraries that can be used by a browser as well as on a server. Web applications that support OAuth allow web browsers to use the authorization information the server provides instead of relying on the user’s password to prove their identity. OAuth allows applications to use an extension mechanism to provide additional security for web applications.
Application developers are encouraged to learn more about OAuth as it is the future of application security. OAuth is used by many large companies such as Google, Facebook and Microsoft, and is being developed by many smaller companies.
Web developers should keep in mind that OAuth requires a little more programming effort than traditional authentication methods like username and password or smart card. However, the application’s security level may be enhanced with the use of an OAuth plugin. Once the application developer creates an OAuth plugin, they may be able to use this mechanism to enhance the security of the application by making changes in the code that are not immediately noticeable.
OAuth also provides additional security by allowing third-party applications to provide access to a web application. For example, if the developer of a site uses Java for their website, they may be able to provide OAuth tokens for third party applications such as Joomla and Drupal to be used on the website to allow users to log into the application. Using OAuth, developers may be able to provide third-party users with access to their application even when the web site is not running. OAuth may be used with the use of a JWT, which is a standard XML format used to encode security and authorization information between the browser and the server.
There are a number of ways that an application can provide OAuth security. One method is to use a secret key, another is to include an X-X-KEY-PEER attribute on the security header of a web page and the last method is to have a cookie with an application-identifier attribute.
When a user clicks on an OAuth link, his browser will send the request to the server requesting a token and this request is handled by the server on behalf of the user. Once the server receives the request, the server will process it and send back the requested resource to the browser to the application. The OAuth token contains a list of the user’s private security details such as username and password. Once the user logs on to the application the user’s browser is given authorization to access the requested resource.
