With the increase in Internet usage and the number of web applications, various security threats have also multiplied. The number of attacks on various web-based applications has increased rapidly over the past decade.

Therefore, web application developers must be aware of best practices to protect their applications. Let me explain some security measures that help protect a .NET application. Try these four ways to maintain integrity throughout the development process.

Sanitize the URL

A developer has many techniques to enable security prevention within an application. However, it is more important to prevent bad data from entering your website. Most security attacks occur when query string values ​​are passed through the URL. The best security practice is to define a common place to whitelist the URL.

Clean up the URL with a set of whitelisted characters and remove all the bad ones. So I wouldn’t encourage characters other than the whitelist set. Remember that blacklisting is not a fail-safe method as a hacker can easily get through it.

How will you encode the data?

While processing and sending, we must always encode the data in the response obtained outside of the confidence boundary. Remember that the type of encryption varies depending on the handling of untrusted data. Encrypting the data causes XSS scripts to remain inactive. Prevent it from running. Microsoft now provides the AntiXss library, which equips a developer with sophisticated coding methods.

Securing service calls

It is important to know if you are exposing WCF services through basic HttpBinding. However, the transmitted message will appear as plain text. Intruders will be able to catch the request and easily stimulate them. You can use wsHttpBinding to transport the messages in an encrypted format. This will prevent unauthorized access to the transmitted data. Regardless, it is always better to host services under an SSL layer.

Turn off the ViewStateMAC

It will create a security hole in the .Net application as soon as you turn off ViewStateMAC. It happens if you use ViewState in your web pages. Intruders will find this easy to intercept. They will read the 64-bit encoded values ​​and modify the values ​​to exploit your website and compromise the security of any user. If you turn it on, it ensures that your ViewState values ​​are encrypted, but also performs a cryptographic encryption using a secret key.

It is important to gain control over your .Net application by building strict security walls. As security attacks are increasing in frequency and severity, we must act diligently. The result of each attack varies depending on the scenario. Because we want to protect our customers’ intellectual property rights, protecting their assets will also help us to ensure our company’s reputation.

The procedures discussed in this article for securing .Net application development can help protect and minimize security vulnerabilities in the future.
