Secure ASP.NET core applications


Security is a vital aspect of any web-based application. If your goal is to build a secure web application, a good understanding of ASP.NET will undoubtedly come in handy. In this context, security revolves around ensuring that data does not fall in the wrong hands.

The elements of security regarding web applications include restricting access to certain data, user identification and verification and safeguarding information transmission. ASP.NET core is arguably the best tool for securing your applications.


Why Choose ASP.NET core?

ASP.NET allows developers the freedom to manage and configure security settings according to their requirements. The process to achieve an appropriate security configuration is straightforward because ASP.NET core has features that can:

  • manage authorization
  • oversee data protection
  • enforce HTTPS
  • manage CORS

With these features at your disposal, you can build secure ASP.NET core applications that will keep hackers at bay.


Best Practices

Although ASP.NET is tremendously secure, you cannot live anything to chance. As a result, you will still need the activities surrounding your application. So how can you secure your applications?

Cross Scripting

Cross-scripting attacks are some of the most common threats to web applications.  One of the ways to evade them is to ensure your database only has validated data. On top of that, use predominantly regular scripts on the server-side and the client-side of your application. You can get one of the best ASP.NET Core applications on Virto Commerce.


Use HTTPS and SSL.

Also, you want to make sure that you are using HTTPS and SSL. This is because the security provided by  SSL safeguards information well. It is nearly impossible for anyone to bypass it. Besides that, HTTPS can also help protect your ASP.NET adequately.

Update Your Libraries and Framework.

Whenever you want to work on a project, stay away from older frameworks and libraries. The goal is to ensure that hackers don’t have anything familiar to work with. Well-established tricks and exploits cannot help them to breach up-to-date frameworks and libraries as easily as for unpatched systems.

Cross-Site Request Forgery (CSRF)

Cross-site request forgery is another common threat to web applications.  In this kind of attack, a malicious website sends spoofed requests to the user. Anti-forgery tokens help to thwart such attacks. Normally, users will request these tokens and the server will send them. The tokens are either stored in the cookies or in the header.

Clear cookies when logging out.

Applications generate cookies from the browser we use. If you leave these cookies intact, you give hackers an advantage. They can use these cookies to access the application and pertinent data. This threat is referred to as Session Fixation Attack.

Advantages of ASP.NET Core

Once you learn the best practices of ASP.NET Core, you build secure applications for your business. The framework is faster than its counterparts. Also, it is an open-source framework with over100,000 contributors.

ASP.NET core works on Windows, Linux, Docker and macOS. This offers unrivaled flexibility to users no matter which of these operating systems they prefer.

If you have been wondering about which framework is more secure for your applications, you can never go wrong with ASP.NET Core.
