How to Make Your Dot Net Application Secure?

With our increasing digital dependence, the cyber threats have got more real over the past decade and they are likely to increase over time. It hereby calls for more secure development practices so that your applications which are very critical to your business remain devoid of vulnerabilities to the maximum possible extent. Therefore, we are going to discuss about the best practices that our team of highly skilled ASP.NET Specialists follow to maintain integrity throughout the development of dot net applications. Read on and secure your dot net applications in the following four ways:

Encoding the data to mitigate XSS

When data is fetched outside the trust limit, it is recommended that you always encode the data while processing or sending. This enables you to make scripts used in the cross-site scripting (XSS) to remain inactive and averts its execution. However, the type of encoding differs based on the non-trusted data you need to handle. With regard to .NET framework, Microsoft provides the AntiXSS library which equips dot net specialists with advanced encoding methods.

ASP.NET team forbids EnableViewStateMac=false

MAC stands for Message Authentication Codes in this context and it is a cryptographic code generated by the server and affixed to the _ViewState hidden form field. The MAC makes it sure that the client has not tampered with these fields. By default EnableViewStateMac=true and by setting this value to false you were making your application vulnerable to cross-site scripting. However, since the release of ASP.NET 4.5.2 it forbids applications from setting this insecure switch to address the issue head-on and prevent potential remote code execution attack.

Basic HttpBinding vs. wsHttpBinding

It is very crucial for you to know that if you expose the Windows Communication Foundation (WCF) services through basic HttpBinding, the transmitted messages will appear as plain text and intruders can easily trap and manipulate them. Instead you can transport the messages in an encrypted format by using wsHttpBinding and avert unauthorized access to the same. However, our web development experts recommend always hosting services under an SSL Layer.

Sanitizing the URLs

To enable preventive security measures in an application you may implement many techniques but it is critical to prevent malicious data from entering your website. As most of the cyber attacks happen while the query string passes through the URL, defining a common place in order to whitelist the URL would be a better security practice. Thus cleaning the URLs with a set of whitelisted characters would ensure that all others apart from this set are discouraged.

It is very critical for you to make your .NET application secure and we can be your partners in protecting your intellectual property assets. We are an ASP Dot Net Development Agency committed to development best practices in order to minimize security vulnerabilities.
