We have an ASP.NET webform site that is getting hit with hundreds of attacks daily. So it has forms that do allow query string and we do allow that but we have several people that are running thousands of scrips to exploit this ability. The are hitting our server at an unbelievable rate and this is causing the site to crawl. Simply put we need to take all precautions we can from being hacked and running unauthorized scripts. We need someone familiar with c# ASP.Net webforms.

I briefly go through the problem you mention, but one thing I want to know here that the script you mention that user running thousands of script what type of script is this? Is this any task that user performs or anything else? And also I want to know that your several users how to use this web form, is there any authentication for each user or not? Scripts are hitting our server at an unbelievable rate and this is causing the site to crawl. Its may be due to the sql injection attack. If it then needs to prevent it from your site. I also prevent it in one of my Asp.net site. 1>To do this I Used parameterized queries (SqlCommand with SqlParameter) and put user input into parameters. 2> I didn't build SQL strings out of unchecked user input. 3>I didn't build a sanitizing routine that can check user input for every kind of malformedness. Edge cases are easily forgotten. Checking numeric input may be simple enough to get me on the safe side, but for string input I just used parameters. 4>I Check for second-level vulnerabilities that are I didn't build SQL query strings out of SQL table values as these values consist of user input. 5>Atlast I Used stored procedures to encapsulate database operations. I already develop many web form projects with Asp.net, Asp.Net MVC, Core, framework 4.7 etc. Faced with many issues like this. If you can share your project by sharing your screen with me through TeamViewer I can give you better suggestions on it. Ping me for discussion.
