In the broadest sense, the security of computer systems encompasses many subjects and techniques, ranging from encryption schemes to availability and disaster recovery systems. However, it is not the goal of this chapter to discuss such a wide range of themes. So, in the following sections we will be addressing these subjects, from both theoretical and practical viewpoints, using ASP. This chapter is complemented by the following chapter, which will focus solely on the OAuth 2. The confidentiality and integrity of transferred information are important security requirements that must be addressed when you are designing and implementing distributed systems. Unfortunately, the HTTP protocol provides little support in this area.

Four Most Used Authentication Methods
NET Authentication is used to protect our applications and websites from unauthorized access and also restrict users from accessing information from tools like postman and fiddler. In this article, learn how to implement authentication using Web API. To access the web API method, we have to pass the user credentials in the request header. If we do not pass the user credentials in the request header, then the server returns unauthorized status code indicating the server supports Basic Authentication. Now, we use the actionContext object to check if the request header is null or not.
Client-side HTTP request with Authorization Header
API security can be complex. With just a few lines of code, Okta can handle all the complicated and time-consuming security elements and let you concentrate on creating a stellar API. Because OAuth 2. With OAuth 2. Second, the client sends a request to the API with that access token and the API verifies it and either authorizes the call or rejects it with a Unauthorized response. NET Core framework to create a.
This article is about OAuth 2. REST Web API is a light-weight essential component of web development in order to share the data across multiple client machines or devices e. Also, we as the owner of the server have no way to verify who is utilizing our REST Web API, whether it's the clients that we have allowed access to or if some malicious user is also using our API s without our knowledge. Let's compare OAuth 2. Today, I shall demonstrate OAuth 2. You can download the complete source code or you can follow the step by step discussion below. The sample code is developed in Microsoft Visual Studio Enterprise. Step 2 Install the following NuGet packages into your project, i.
