Security Features of ASP.NET

The security needs for an organization are governed by their business needs, domain etc. Apart from it the application now days can be accessed from various platforms and devices. There is a big boom of social networking applications as well where the services are exposed to public over internet. The users prefer to use their social networking ids for authentication and authorization. All this is leading to security vulnerabilities and there is tremendous need for building applications that are not only highly secure but also provide seamless and simplistic behavior to the target user accessing the application from any device.
Over the years ASP.NET has provided features like form authentication along with membership and roles to implement security in web applications. With the changing needs of authentication such as using external login credentials, providing two factor authentications or using claims for authentication Microsoft has introduced ASP.NET identity framework that provides all these features out of the box for implementing the security needs of the application.
ASP.NET identity is based on OWIN authentication middleware for securing the web applications. ASP.NET Identity can also be used to support multiple storage mechanisms such as Relational Databases, No SQL, and Azure Storage etc. It provides social logins for providers like Facebook, google etc. and claim based authentication. Some of the other features include two factor authentication, account lockout, account confirmation, password reset etc. All in all ASP.NET Identity provides a complete framework for building secure web apps, phone or hybrid applications.
ASP.NET Identity provides some very robust features to address our security concerns within web applications. It provides an enhanced mechanism to manage the user credentials and ensuring that credentials are securely persisted in our data stores. It can be used to implement claim based authentication and authorization within our applications which is very important if we are creating distributed applications that require users to be authenticated from multiple devices such as web, mobile, tablets etc.
With features like social login and two-factor authentication it is a perfect fit for modern day web applications that need such features to be integrated within the application for simplistic login behavior and at the same time be highly secure against vulnerabilities. It also provides the developers a great framework that can be customized according to their requirements, can cater to variety of data stores and they don’t need to write a provider from the scratch for implementing security.
