Common ASP.NET Application Security Flaws

For highly secure ASP.NET Web applications, such as Internet banking sites, you may want to implement a more secure solution for user authentication than the user name and password combination. You can use client-side digital certificates to verify the identity of the user. In addition, you can map client-side digital certificates to Windows accounts on the server if necessary.

There is a wide array of attacks that ASP.NET web applications need to protect against but most security holes are due to flaws in the following:

Authentication... makes easier for attackers to reveal the User’s credentials, or worse to dig down the application’s authentication altogether. The secure password policy, brute force attacks and password hashing are the part of authentication mechanism.

Authorization… Allowing logged-in users to perform actions without authorization verification. This can possibly be ensured with all ASP.NET web pages in a consistent manner.

Data validation… is all about trusting data submitted by the User and then acting upon it. It is generated by the lack of data consistency throughout the web, and failing to encode the data sent to the server.

App configuration… is about using some default configuration on the application and hosted server. Different applications require different configurations but the focus of this section is on those that fall under the responsibility of the web developer.
